#anth438 15. The similarities between humans and carnivores is very interesting, and may be based in a a meaty (high quality) diet.

[David Wood @davidwood667]

#anth438 14. The authors controlled for gregariousness (but found it had no effect), but not for other cognitive tasks (extractive foraging)

[David Wood @davidwood667]

#anth438 13. This article supports the energetics explanation for human altricial and encephalized birth as opposed to the OD explanation.

[David Wood @davidwood667]

#anth438 12. They also think efficient walking, and more stable energy intake from cognitive and physiological compensations for seasonality

[David Wood @davidwood667]

#anth438 11. The authors don't think that allocare/provisioning entirely explain bigbabybrains and altricial births.

[David Wood @davidwood667]

#anth438 10. Humans have a ton of allocare/provisioning since we are cooperative breeders. This may explain out short IBI and large brains.

[David Wood @davidwood667]

#anth438 9. In callitrichids, allocare increase fertility. But babies are born very altricial and with small brains because they twin also.

[David Wood @davidwood667]

#anth438 8. Allonursing decrease the interbirth interval and increase fertility. This is a common strategy in platyrrhines.

[David Wood @davidwood667]

#anth438 7. Primates (especially platyrrhines) with more allocare are born more altricial.

[David Wood @davidwood667]

#anth438 6. Direct forms of help (provisioning, carrying, nursing) had a larger effect on brain size than indirect forms (huddling).

[David Wood @davidwood667]

#anth438 5. Species with non-maternal provisioning had bigger brains than species where only thee mother fed the offspring.

[David Wood @davidwood667]

#anth438 4. Primates almost always provide more allocare than protection, while other animals show very little.

[David Wood @davidwood667]

#anth438 3. authors compared 445 types of mammals (primates to carnivores) in brain size, types of allocare and precocial/altricial babies

[David Wood @davidwood667]

#anth438 2. Humans have big brains and a high reproductive rate. These seems to be at odds. Perhaps because of allocare and provisioning?

15. If reproductive suppression is linked to stress, do individuals with stress disorders exhibit amenhorrea? #anth438

14. How can Geladas miscarry on the day a new male takes over? That seems like to fast a response to be from the endocrine system #anth438

[David Wood @davidwood667]

13. If stress doesn't come into play in reproductive suppression of callitrichids what else could the mechanism be? #anth438

[David Wood @davidwood667]

12. The mechanism for this model isn't well understood. More research is needed in the HPG axis and its functioning in situations. #anth438

[David Wood @davidwood667]

11. It would be interesting to see if this model relates at all to Orangutan male bimaturism. #anth438
