The article says, "Thus, from the size of an animal’s neocortex, the
frontal lobe in particular, you could theoretically predict the group
size for that animal". So I did a bit googling and found another article, here
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1626378/ http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1626378/
This one has another interesting point:
"These analyses show that while relative neocortex size is positively
correlated with female group size, it is negatively, or not at all
correlated with male group size. This indicates that the social
intelligence hypothesis only applies to female sociality."
Perhaps after a man gets married with a woman, he could shift much of
his social function of the neocrotex to his female partener, and free
up that part of the brain for some other interesting stuff...
- 2510c39011c5 12y agoAssuming in a typical courting relationship network, a female is being courted by 8 males at the same time, and assuming all those men would devote much of their resources to their courtship and hence would have few resources to spare for other inter-personal relationships, it looks like the neocrotex of the female would need to take on more burden (e.g. more developed) as to take care of those 8 links, than the neocrotex of each man needs to maintain a single link. This may explain why most of the time woman is more adept at dealing with those sociality issues. male_0 male_7 o o | o male_1 \ | / \ | / \ | / \ | / male_6 \|/ female o---------o---------o male_2 /|\ / | \ / | \ male_5 / | \ o | o male_3 o male_4
