Veganism?

Larger, or more complex?
 
I'm leaning towards more complex, but I don't exactly recall what was stated in the article I was reading.
 
In that case, it's an interesting debate considering that some marine mammals have more complex brains than humans, including orcas... who are primarily carnivorous.
 
I believe with complexity came size. It also created gestional and reproductive problems. Larger heads and a limited amount of space thru which they can pass at birth. Early birth eventually became the 'norm', with most of the development taking place outside the womb. This early birthing required behavior changes in the species in order to remain viable.

I wonder if the gestational time has changed from early early mankind to today?
