The human brain did no grow larger and gain intelligence until it ate meat. anyone ever ask this question? What di man need in order to survive winters before we had 24-7 availability to fresh vegetables though the winter, that they did not have? Go ahead, try to survive through a winter as a hunter gatherer without eating meat. Good... when the SHTF they will drop like flies because they are idiots.
Problem.
Chimps eat meat.
Often still alive and screaming meat.
If meat was going to cause the brain to suddenly grow larger and gain intelligence then Chimps should be up there right along with humans.
But they are not.
And like most people you confuse vegan (a totally stupid new fad diet) with vegetarian (a balanced diet that dates back thousands of years).
The human brain did no grow larger and gain intelligence until it ate meat.

Do you believe that the first human or humans was/were conceived by, borne by, and born to, non-human primates?
You appear to be articulating a tenet of the Theory of Evolution, so I thought I’d ask for clarification.
