The Waterside Hypothesis Requires a Rethinking of Human Evolution

In a 2016 September BBC radio program titled “The Waterside Ape”, Sir David Attenbourough presents new evidence for the waterside theory that have been published in recent years. In the program, they interview free diver Sara Campell who went from a total beginner to a holder of three world records in just eight months, Erika Schagatay who have studied Japanese Ama divers and Bajau divers and compared the data with semi-aquatic mammals and Curtis W. Marean who has discovered dependence on mussels and sea-snails among Homo Sapiens at Pinnacle Point in South Africa at 164 k years ago.

Surfer’s Ear Hard Evidence for the Waterside Hypothesis

A particularly interesting evidence has been formulated by P.H Rhys-Evans and M. Cameron in their article “Surfer’s Ear (Aural Exostoses) Provides Hard Evidence of Man’s Aquatic Past” in 2014 in which they show that aural exostoses have been found not only in old Homo Sapiens fossils but also in Homo Erectus and Homo Neanderthalensis fossils. Surfer’s ear is a bone growth in the ear canal that protects the eardrum from pressure, which is proportional to the time spent in cold water. The bone growth has been found in fossils stretching as far away as South Africa, the Mediterranean and Australia. According to Rhys-Evans this bone growth can only be explained by extensive swimming in cold water.

Critical Response in The Conversation

After the program was released, critics Alice Roberts (Professor of Public Engagement in Science, University of Birmingham) and Mark Maslin (Professor of Paleoclimatology, UCL) wrote a reply in The Conversation with the title “Sorry David Attenborough, we didn’t evolve from ‘aquatic apes’ – here’s why”. In the article, they claim that many of the adaptations that are suitable for an aquatic environment, as for example hairlessness and increased body fat can be explained by a need of cooling down and sexual selection. They also claim that many of our aquatic adaptations evolved on different occasions throughout human evolution, why water cannot be the explanation. Bipedalism, for example, emerged about 6-7 million years ago while our brain started to enlarge about 2 million years ago. They also highlight the flexibility of human behaviour, and they explain later water adaptations as for example the one mentioned in the Pinnacle Point starting at 164 000 years ago, as behavioural adaptability rather than as an inherited way of life.

But why rely on sexual selection? What is attractive in generally what is viable in terms of survival. Hence, if humans started to like hairless bodies and more fatty breasts, it was rather because these characteristics were evolutionary useful, not only that they were considered beautiful. And is it really a problem that different characteristics have evolved on different occasions? The increase of brain size in Homo Erectus is probably much linked to the emergence of deep water Rift lakes that enabled increased feeding from aquatic resources. Hence, the aquatic phase in human evolution was not something that just took place many millions ago right after we left the trees, it has been influencing our evolution till the very emergence of Homo Sapiens.

Misleading and Deep-rooted Criticism against “Pseudo-science” and lack of Fossil Evidence

Bluntly, Roberts and Maslin also criticise the theory for being “pseudo-science” as is does not make any falsifiable predictions, of course irritating many of the researchers outside the area of palaeoanthropology who respectively have found strong evidence for an aquatic past in the fields of for example human physiology, obstetrics and otorhinolaryngology. In a falsifiable experiment, it has also been shown that vernix caseosa, the white substance found coating the skin of new-born human babies is likely to be an adaptation to entering water soon after being born. Further, obviously without listening carefully to the BBC program, Roberts and Maslin also claim that there is no fossil evidence to support the waterside hypothesis even after the discovery of surfer’s ear in Homo Erectus, as well as predation and preparation of very large catfish in Turkana basin at two million years ago, and the fact that literally all well-known fossils as Lucy and Selam have been found in river sediments. Lucy was found next to fossilised crocodile and turtle eggs.

Some of the researchers who participated in the program responded to the criticism from Roberts and Maslin here: A reply to Alice Roberts and Mark Maslin: Our ancestors may indeed have evolved at the shoreline – and here is why…

The Scientific Evolutionary Story of Man is Closely Related to our Belief in Development and Constant Growth

It is sad that the Aquatic Ape/Waterside theory since long has been misunderstood and rejected without further thought. This is also being reflected in other books and magazines dealing with human evolution. Mostly, the savannah or mosaic theory are taken for granted, and forms a basis for further reasoning. This is also the case with the great selling author Yuval Noah Harari, who has written the books Homo Sapiens and Homo Deus. When he talks about our evolutionary past he always relates to the savannah, even though there no longer is any savanna theory out there. Hence, many scholars adapt to the paradigm set by the paleoanthropologists, but which is false. We also have to keep in mind that the concept of human evolution is closely connected to our belief in development and growth. The generally accepted evolutionary story of Homo Sapiens is in fact the scientific creation myth of man, and it repeatedly depicts a human ancestor who were living in a diverse mosaic environment always eager to adapt to new circumstances using an emerging intellect and creativity, and not it’s bodily functions. There is thus a red thread between myth of human evolution and today’s pursuit of constant growth.

The Waterside Theory Requires Another Story of Human Evolution

But the aquatic ape theory tells us another story: here most human characteristics can be explained in relation to a specific biotope: the waterside. However, this idea can’t be accepted by the paleo anthropologists because It implies another creation myth that does not go hand in hand with the idea of development. Hence, by strengthening the waterside theory, the proponents of the theory just make it more inappropriate in the anthropological community. That’s why they compare the theory with the mythological hydra: if you cut off one head, two new ones grow out.

The only solution to this dilemma is to accept the fact that humans during evolution were nothing special. We were not the masterpiece of creation. We were just one animal among others. We ate shellfish that we collected in low tide or by diving. We were walking, wading and swimming long distances along the shore lines. We gave birth to the children in water. And, most importantly, we were not creative engineers, who always came up with new ideas for survival. There was no need for constant invention – because their world was never changing as rapidly it does today. What was important to our ancestors was to learn the techniques of survival that were already in use. What was important to our ancestors was to learn the techniques that were already in use, ranging from tool manufacturing, motor skills and resource utilization. They also inherited a profound knowledge about edible plants and marine resources. As a matter of fact, if we look at the tools used by our human forefathers we can see that they were made in nearly identical ways over long periods of time. The stability and the conservatism in the tool making traditions as for example Oldowan stretching from 2.6 million years BP to 1.7 million years BP, Acheulean stretching from 1.76 million years BP to 100 thousand years BP and Middle Stone Age (MSA) starting around 280,000 years ago and ended around 50–25,000 years ago have been extremely conservative over hundreds of thousands of years. Where were all the innovations? And why did the early group of Homo Sapiens that made it all the way to Israel around 130 – 85 thousand years ago not out conquer the Neandertals? Why were the same caves inhabited alternately by both Homo Sapiens and Neanderthals before Homo Sapiens finally disappeared from the area?

In fact, what distinguished man throughout history was rather an extremely precise handwork, a strict repetition of long series of complex hand movements; or in other words: a repetition of already acquired technology. And not a constant flow of inventions and change.

A New Paradigm Which is not Based on the Idea of Development is Required

We must accept a new paradigm – that humans were not ingenious creators but rather extremely skilled imitators –  and I am convinced that this paradigm will grow in popularity when we fully realise the destructive impact humanity and rationality have on this earth. Soon, the believe in development will not lay the foundation of the scientific creation story of man.

But then, what happened? Why did Homo Sapiens finally change and start to migrate to the most diverse environments? Yuval Noah Harari talks about a cognitive revolution that took place approximately 70 000 years ago enabling us to organize people on a larger scale in relation to a common shared world view. The revolution also led us to manufacture more advanced tools, create more diverse art and hunt on a large scale. Yuval Noah Harari argues that changes in our DNA enabled this change. Again, we can see the strong faith in the connection with human evolution and today’s growth, and the conviction that today’s humans reflects the inner core of our DNA. In other words, the paradigm assumes that we are meant to be geniuses.

But can small changes in brain make that difference? And if so, what was the purpose of our large brains that we had as early as 200 000 years ago despite not creating any visible inventions?

We Must Rethink our Brain and Language

There is, as I see it, only one possible answer to this dilemma. The creative capacity of man throughout most of our evolution was latent. It was a part of our brain and potential, but not utilized. It evolved, but as the other side of the coin. The main function of the growing brain was rather to repeat earlier invented behaviour, not to start the day by coming up with an ingenious idea about luring a big prey. We also must keep in mind that tool management and language are located in the same part of the brain and closely related to each other. Hence, the function of this part of the brain was to cement behaviour and movements, to master the art of reappearance. But when the humans had to leave their tropical environment because of climate change – as in South Africa approximately 100 000 years ago – this language lost its grip and turned creative. In other words, maybe the brain in its essence is anti-development. That, I am sure, will be the paradigm of tomorrow.

Video: Bajo Man Bites an Octopus Between it’s Eyes

I recorded the following video during my trip to Kabalutan, Togian, Indonesia, in February this year. The octopus was caught with a speargun and lured with a fake octopus.

Bajo in Kabalutan still stick to their traditional fishing methods while the waters around them are being depleted by big commercial fishing vessels.

Attending the 2nd International conference on Bajau/Sama’ in Semporna

Between March 23-26 I attended the 2nd International conference on Bajau/Sama’ Diaspora and maritime Southeast Asian cultures in Semporna. It was an interesting conference with skilled scholars who presented papers about long epic songs among Indonesian Bajo (iko-iko), more than 3 000 years old archaeological sites in Semporna and much more.

Presentation on Sama Dilaut Challenges

During the conference, I made a presentation about the contemporary challenges facing Sama Dilaut in both Philippines, Indonesia and Malaysia and discussed possible solutions to the crisis. Sama Dilaut are facing a variety of problems, as for example indebtedness, reduced fish stocks, lack of ID:s and market distortion, and there is no easy fix. You can see my Power Point-presentation from the conference here: Sama Dilaut as Guardians of the Sea. My conference paper will be published later.

Another problem that are facing Sama Dilaut in Sabah are new regulations on use of engines. Many of the smaller engines used to be put inside the boat are now illegal and as a consequence many more Sama people are now using sails than before. The new regulaitons have been in place for little more than a year and has made search for livelihood increasingly difficult for many Sama Dilaut. 

In the conference, archaeologist Dr. Stephen Chia presented findings of old pottery stoves on the archaeological site Bukit Tengkorak that is more than 3 000 years old and has more or less the same appearance as present day pottery stoves made by Sama people. This might mean that Sama people have been living in the area for millennia, or perhaps they did learn the handicraft technique of people who were already living there.

Few Sama Dilaut Attended the Conference

The conference in Semporna was truly international, with Sama people from both from Malaysia, Philippines and Indonesia attending the conference. It was great to see this mixture of culture and language and that the bonds between the Sama groups in the different countries gets stronger. I also came to realize that Central Sinama (widely spoken in Philippines and Malaysia) and Indonesian Bajo are more closely related than I previously thought. I also got to know that there is a quite big Sama Simunul community in London, which I might pay a visit.

However, very few Sama Dilaut did attend the conference. Some Sama people with their roots in Sitangkai attended, but no Sama Dilaut from Zamboanga or Tawi-Tawi. And no one who actually lives on the houseboats today in Semporna was there – and they knew nothing about it.

The conference also attracted other Sama speaking western people from the Philippines, as for example Luke Schroeder, who runs the website It was the first time that so many “Melikan” (westerner) Sinama speakers gathered in Semporna to the local’s great delight.

Traditional Artefacts and Igal Festival

The conference took place in the Tun Sukaran Muesum avenue, where a lot of traditional Sama fishing equipment and musical instruments can be found, as for example different kinds of pana (spear guns) and kuling tangan (a kind of xylophone still played by the Sama). In the evenings, we joined the Igal festival where dance groups from Tawi-Tawi, Semporna, Kota Kinabalu and Manila participated. There was also a competition with two different competition classes, traditional igal and modern igal. A group from Bangaw Bangaw won in the traditional genre.

Facebook Video with more than 400 000 views

After the conference, I stayed in Semporna for almost a week, and I realised that I have become a well-known figure in the area after the release of a Facebook movie from January this year in which I speal Central Sinama – the video now has more than 400 000 views.

During these days, I visited the communities of Labuan Haji, Bangaw Bangaw and Labuan Haji where many Sama Dilaut people without legal papers reside. I also visited some of the outer islands in the region where I met with Sama peoplewho are residing in their houseboats. I was joined by the American film makers Marlena Skrobe and Alice Bungan who are making a documentary about Sama Dilaut.

Famous Sama Girl Identified

Also during this trip, I visited Mabul where I talked to Sulbin, the famous diver who walks on the sea floor in BBC:s movie “Sea bed hunting on one breath”. I asked him about his eardrums and he said that he had broken them for a long time ago “abostak na talingaku”, he said. He also said that it was very painful but that it is easy to harvest the sea floor after it’s done. In Mabul, I also identified the girl who saves her boat and help tourist children in another well-known video on Youtube. The girl’s name is Sial and she still lives in a houseboat outside of Mabul.

Sama Dilaut Photo Book as PDF

Here comes my Photo Sama Dilaut - People of the SeaPhook about Sama Dilaut as PDF: Sama Dilaut – People of the Sea. Over the years, I have distributed approximately 50 copies of the book, which is not for sale but given to people and organizations I meet.

At the moment, I am working on a new updated book that will touch more on Sama Dilaut’s culture and challenges as well as different fishing techniques. It will also contain my most recent photos.

Meeting with AAT Poster Designer Albert Chak in Hong Kong

After the trip to Indonesia I made a short stop in Hong Kong on the way back to Sweden, where I met web designer Albert Chak whom I met in the Human EvolutOLYMPUS DIGITAL CAMERAion conference in London in 2013. He has a great interest in the Aquatic Ape Theory and has made two very informative posters on the matter, after carefully have studied the work of scientists in the field. In two intense days, we discussed different aspects of the theory, as for example it’s health implications and the emergence of speech. We also discussed how we can promote the theory among a larger audience.

My plan is to meet with many proponents of the theory around the world in the coming years as well as baby swimming centres and water birth institutions.



Conference in Semporna on Sama Dilaut

On March 23-27 the 2nd International conference on Bajau/Sama Diaspora and Maritime Southeast Asian Cultures will be held in Semporna, Malaysia. The conference will be about Sama Dilaut culture, sacred places, maritime lifestyle and migration.

I will present a paper on migration in which I discuss two possible solutions on the Sama migration crisis, derived from extensive field trips in Philippines, Malaysia and Indonesia. I argue that the crisis is part of an international problem facing coastal communities throughout the world, and claim that we should reclaim the concept of Sama Dilaut as guardians of the sea. Positive examples can be found in Sampela where Sama fishermen lead a traditional lifestyle within a national park and in Davao were Sama fishermen have been recruited as “Bantay Laut”, with the task of collecting plastic waste and report illegal fishing.



Life of Sama Dilaut – Broken Eardrums, Spear Gun Fishing and Indebtedness

From the end of December 2016 to the beginning of February 2017 I travelled in Philippines, Malaysia and Indonesia where I visited several Sama Dilaut communities. I talked to them about their daily lives, followed fishing and continued to learn the basics of two of their dialects, Central Sinama and Indonesian Bajo.

Noah – one of the last young boys who make a living from spearfishing in Davao

The trip started in Matina Aplaya in the outskirts of the metropolis Davao City in southern Philippines. Fish is on the decline and most people in the village make a living from vending of pearls, second hand clothes and shoes. However, a few families still make a living from the sea, and they are incredible divers.

I have been visiting Matina Aplaya every year since 2010 and I have always been accompanied by Issau and his son Noah. Noah is one of the few boys in the village who has grown up becoming a skin diver along with his father. On daily fishing expeditions, they spear fish and collect sea urchins, sea shells and clams in the coral reefs surrounding the town. It is fascinating to see that Noah has grown up to become a skilled fisherman who contributes to the household with his spear gun.

Zamboanga – Sama Dilaut resettlement after the 2013 fire

In 2013, the outskirts of Zamboanga were struck by a fire that destroyed thousands of houses and displaced thousands of Sama Dilaut and Tausug people. For months, they were living in a temporary camp in a sport arena close to the town centre.

After my visit in Davao, I made a two-day stopover in Zamboanga in western Mindanao before travelling to Tawi-Tawi. I visited some newly constructed villages set up by NGO:s and local authorities exclusively for the Sama, and many of the houses have been built in a traditional way. However, the daily life of many Sama Dilaut in Zamboanga is tough and it is getting harder and harder to make a living from the ocean. Many people are begging in the harbour. Yet others have fled to other cities in the Philippines.

Sitangkai – traditional dance in the Venice of the south

Despite recent kidnapping incidents in the Sulu I decided to travel to Tawi-Tawi in southwestern Philippines. I visited the Sama Study Center and the Marine museum in Tawi-Tawi where I met Rasul M. Sabal, the museum director. He has a keen interest in Sama Dilaut culture and show sincere concern with their challenges.

While in Tawi-Tawi I took the opportunity to pay a visit to Sitangkai along with Rasul M. Sabal and two policemen. Over the last years, very few foreigners have been in the area and I was fortunate to be able to visit the legendary community where thousands of people live in what is called the “Venice of the south” next to a tiny piece of land.

In Sitangkai, Sama elders performed religious dance that is normally performed during the magpai baha’u ceremony, an annual ritual taking place once a year in community (this year it will be held in May and it attracts Sama people from all over Sulu and Sabah). It was great to experience their hospitality and kindness!

I came to know that the interaction between Sabah and southern Philippines is intense despite stricter migration policies on the Malaysian side, and boats are heading between the locations more or less every night. In Sitangkai, I also saw how octopuses were shipped on a large scale to Tawi-Tawi and further to Zamboanga and Manila. However, the production of sea weeds has dropped due to reduced market prices.

Broken eardrums

After Tawi-Tawi, the initial plan was to take a ferry to Semporna, but the ferry company had lost its license so I took another ferry going back to Zamboanga instead. In the harbour of Bongao, more than 20 Sama Dilaut children were diving for coins, displaying great skills.

On the trip back to Zamboanga, I met two Sama brothers from Tawi-Tawi who were on their way to Palawan to join a fishing crew going deep in the South China Sea. They told me that they usually made use of explosives and compressors during these trips, and that the expeditions used to last for about one month. I asked them about their eardrums, and they said that they had broken them. Then, I asked them about their hearing ability, and they told me that their hearing was okay but that they had problems localising sounds. The brothers’ story is interesting since it has been unclear whether Sama fishermen break their eardrums or not. I would say that most the Sama Dilaut divers permanently rupture their eardrums, either on purpose or accidentally, and they take medicine in the case of infection. However, some fishermen do also equalize their ears and some may have hands free techniques for doing so.

When the ferry arrived in Zamboanga day after, the scene changed. Nearly 100 Sama begged for money in the harbour, including elders, and the atmosphere was more tense than in Bongao. It got obvious that life is very difficult in Zamboanga, and it is not surprising that so many Sama Dilaut are now roaming the cities of Manila, Cebu and other Philippine cities.

Meeting with Sulbin on Mabul

After the trip to Sulu, I made a short stop in Semporna where I went to Mabul to meet the Sama community there. I was lucky to meet Sulbin – the diver who walks on the sea floor for nearly two minutes in a widespread BBC production. He told mIMG_0378de that he had just come back from seasonal work in Kota Kinabalu. Hence, also the most skilled fishermen might choose to make a living in the job market rather than make their own fishing trips in the region!

However, in Semporna many Sama Dilaut still live in houseboats and they roam the many islands in search of fish, sea shells, clams, sea urchins and so on. Many of the more traditional Sama have no option but to continue extracting resources from the ocean.

Sama Dilaut spear-gun fishing women Wakatobi

After the short stop in Malaysia, I went on to Makassar in Indonesia where I met up with Professor Erika Schagatay from Mid-Sweden University, for our third trip together. We headed towards the island of Buton in southern Sulawesi where we spent a few days in the village of Topa (the sama village where Erika Schagatay first came in contact with Sama people in 1988). In the village, we followed fishing, talked to the people and made physiological research on Sama divers. For example, we measured the diver’s lung capacity, spleen size and feet size.

After the stay in Topa, we took a ferry to Wangi-Wangi in the Wakatobi island group. We spent one day in Wangi-Wangi before we visited the village of Samepla further out in the archipelago, where we spent four days. Sampela is located more than one hundred meters from the island of Kaledupa and have got attention in several film projects throughout the years, in for example BBC:s series “Hunters of the South Seas” and the movie “The Mirror Never Lies”. During our stay in the village, we joined a group of women spearfishing, and it was fascinating to see their acquaintance with the ocean. We also followed fishing with Tadi, a 70-year-old fisherman who is still an incredible fisherman. He was the most successful fisherman during our trips, outperforming much younger spear gun fishermen. We also got the opportunity to measure Tadi’s spleen, and it turned out that his spleen is much bigger than peoples at the same age and with the same body size, and whom do not make a living from diving. The spleen is a very critical organ for experienced divers, since it consists of a high concentration of blood cells that can be released under pressure.

Also in Sampela, life is getting more and more difficult because of decline in fish. In the community, there is also a problem of indebtedness and large interest rates. Hence, many Sama fishermen are forced to increase fishing efforts despite recent decline in marine resources. Or in other words, they live on resources yet to be extracted.

Sampela is located within the Wakatobi National Park, but nevertheless, too little is done to prevent over-exploitation of the area. Big fishing boats enter the waters even though only small scale fishing methods are allowed. Hence, more must be done to reinforce the park regulations and to protect the area and the people living there.

Kabalutan – a pregnant woman showing great diving skills

My last visit in Indonesia took place in the community of Kabalutan in the Gulf of Tomini, central Sulawesi. Also this community is known from a few TV productions. Here, BBC produced a short documentary about Sama Dilaut with Tanya Streeter in 2007, in which young Sama children dive 12 meters repeatedly displaying great skills. This is also the place where Svea Andersson’s depicts a eight month pregnant woman diving for shell fish in the movie “Sulawesi, the last sea nomads”.

Along with two Sama families, I followed on a pongka fishing trip – a fishingKabalutan Kid 2007 and 2017 - Muspang trip at sea lasting for a few days. We stayed two nights at sea, collecting shell fish and spear-gunned fish. Among those who followed were 17 year old Muspang, the youngest boy in BBC:s movie with Tanya Streeter He is already a father and a great diver. However, I was more impressed by his mother, the same woman that was highlighted in Svea Andersson’s movie. Again pregnant, she was diving up to eight meters in search for shell fish and clams, as well as spear gun fishing. She is one of the last free diving Sama women with great diving abilities; one of the few remaining in not only Kabalutan but most likely in most Sama communities throughout Southeast Asia.

However, the amount of large commercial fish in on the decline also in Kabalutan, and it will be difficult for Sama people to sustain a living at the sea. Shell fish and octopus are still in quite big numbers since they mostly are being extracted using traditional fishing methods including diving, but other fish are rare. Who knows what life will look like after just 10 years when the consequences of coral bleaching and rising ocean temperatures will be much more severe than today?
