Yes, it's incredible, but this nonsense is still repeated over & over.
You succeed in academia by listening to the professor and the regurgitating every word EXACTLY. You do not get good grades by rejecting what you are
told.
In certain instances this makes a lot of sense. You really can't compromise with the laws of physics. You order yourself up a new periodic table. And in any type of math, you do it the right way or you get the wrong anger. So this rigid education system, this punishment of free thinking serves us well...
EXCEPT when you move away from the strictly objective to the subjective.
There is no strict answer for human evolution, our origins, and there isn't even
a solid method for collecting evidence... or determining what is and is not evidence.
What it boils down to is that 1+1=2 is a fact, but in paleo anthropology pretty much everything is an opinion. People collective evidence -- or what we think of as evidence -- and then interpret it.
Even DNA: The labs can determine EXACTLY what it looks like, but there is nothing in this world that tells us how it got that way. Every explanation is mere theory...
If we had left the forests for the savanna or so, we had had a fur protecting us from the sun, no naked skin, no abundant water+sodium-excreting sweat-glands, no thick fat-layers, not flat plantigrade feet, no heel-walking, no
atrophied olfaction etc.etc.etc.
The beauty of Aquatic Ape is that there is room to adapt. Monkeys can eat shell fish, they don't have to first evolve into upright walking tool users. That can come
later. Doesn't have to, but it can.
The savanna nonsense pretty much requires adaptation FIRST. They have to
evolve FIRST, they need adaptations FIRST before they take to the savanna. And, again, aquatic ape provides the answer...
They exploit the sea. There's an over supply of proteins. The sea supports a higher population density. But it also guarantees us a periodic movement
inland in response to conflicts, natural disasters, changing sea level (etc).
The higher your population density, the more vulnerable you are to even short term disruptions of food. So occasionally they followed streams inland, or
they got trapped by rising sea levels or they were driven off by conflict and, BAM, they're in a new environment. They've got an upright stature, bigger brains, tools and they need to innovate to survive...
