Did humans come from the seas instead of the trees ?

3. why do anthropologists have such paradigm anxiety?

They're even more vicious than linguists about their grand theories.

People who proposed Neanderthal/Homo Sapiens Sapiens inbreeding were mocked for decades too.

I get scholarly disagreeing, if people are respectful about it. But the vociferousness of these attacks on other theoretical positions strikes me as odd in a field where by definition entire theories hinge on a particular (and random) discovery of a fossil (and can change with a new finding.) It seems like if one's theoretical position could be that quickly discredited, one might be a little more humble about it.

That said, I remember reading The Aquatic Ape and parts were intriguing and parts seemed oversold, but it did always raise some questions that didn't seem adequately addressed by other theories.

But I'm a layperson, so I'll refrain from judgment.
