Before I get into it, just know the pictures just serve as visual representations, not actual pictures
Okay so anyway, evidence for this theory is the following:
THE FACT THAT HUMANS ARE SO HAIRLESS:
Only two kind of habitats give rise to hairless animals, an aquatic one and a one below the ground (a naked mole rat for example)
.The suggestion that humans have become hairless to prevent overheating has been rendered false because hair can act like a defense against the sun.
This is why camels retain their fur even in the hot dessert environment.
OUR FAT CELLS
We have ten times the number of fat cells as expected in an animal our size. Only two types of animals have large fat cells: hibernating and aquatic ones.
In hibernating it’s seasonal fat, but in aquatic it’s all year round. It’s unreasonable to think that we evolved this feature in land because large fat pockets would have just slowed us down.
Primate babies are always born slender, but human babies start to develop fat even before birth.
WALKING ON TWO LEGS
So we’re the only mammals that have developed bipedalism. This is a surprise, because walking on 2 legs vs. walking on 4 legs is very disadvantageous. It’s slower, unstable, our organs are vulnerable to damage.
One theory is that if our habitat was flooded, we’d have to walk on two legs to keep our heads above the water.
The only animal who has ever evolved a pelvis like ours, the swamp ape, used this method.
We have conscious control over our breathing. Ever other land animal doesn’t. Mammals like dolphins and seals also conscious control because it tells them how deep they are going to dive and they can estimate how much air they need to inhale.
Our body is so wasteful of salt and water. Think of tears and our way of sweating. Other land mammals don’t have this. Water mammals do however.
Okay anyway I hope you learned something.

Okay, there are a handful of things wrong with this.
- "Loss of body hair" - We haven’t lost our body hair. It’s small and fine, yes, but humans still have the same amount of hairs as Chimpanzees.
- Bipedalism - It’s misleading to say that it’s disadvantageous. It’s actually more advantageous in many aspects. It allows us a more efficient gait, requiring far less effort to remain upright while walking. All we have to do is stabilize the muscles to keep our joints ‘locked’ so we don’t fall over. It also allows us to run incredible distances which is extremely advantageous while hunting. Most animals can outrun us over short distances, yes, but they tire much sooner so as long as you don’t give up or lose the trail, you will catch up eventually.
Also, to say that bipedalism is slower is simply not true. Humans are slower than many other animals, sure, and we happen to be bipeds. But many, many other animals are both bipedal and very fast. In fact, many reptiles switch to running on two legs when they have a need…a need for speed.
- Sweating - Is not wasteful at all. Yes, we lose salt and electrolytes through our sweat but we also rid ourselves of a tremendous amount of heat. Humans can stand temperatures up to 55 °C/131 °F and remain there for a matter of hours before succumbing to hyperthermia. Because of this, humans are able to withstand the midday heat in many of the hottest parts of the world while most everything else needs to lay down in the shade and pant constantly or else they die of heat. This can play a big role in hunting as well. While we can stroll about in the most intense heat of the day, other predators that would, otherwise, run us off or kill us, are restricted to their shady retreats. They simply cannot expend the energy to come after us, giving us all the prey in the world unable to fight or flee.
- "Swamp Ape" -More commonly, Skunk Ape. According to the US National Parks Service, the Skunk Ape does not exist. It is a creature who’s existence has yet to be verified, much like Bigfoot.
Though this may be referencing the long-extinct Oreopithecus. But I haven’t found anything actually referring to it as the “swamp ape”, only a link at the top of the Skunk Ape Wikipedia article saying “"Swamp ape" redirects here. For the Miocene primate, see Oreopithecus.” I also haven’t found much of anything linking it’s pelvis to that of the human other than that it allowed it to walk on two legs, though that is hardly cause to call it the same as other primates have developed similar pelvises.
- Subcutaneous fat - Humans are in no way unique in the ape family for our subcutaneous fat.
From what I can see, this is essentially information digested and regurgitated a little differently several times over, stemming from writer (not anthropologist) Elaine Morgan’s books inspired by Alister Hardy’s Aquatic Ape Hypothesis which, it should be noted, is not regarded with much faith in the scientific community, as it is unsupported by the evolutionary fossil record.
