Counterpoint: pregnancy proceeds until it hits a hard metabolic limit, and the global differences in pelvic structure imply birth canal is not the limiting factor https://www.ncbi.nlm.nih.gov/m/pubmed/30146522/ …pic.twitter.com/RPSbJWkw25

so it's not until you break the pelvis just to get out there but until the baby is too much of a vampire for the mother to bear? we still get higher perinatal mortality than close relatives, but can believe it's not *the* factor

another fave paper on this is how our babies are fatty not to keep warm (other species with this problem don't solve it like that) but to get energy reserves to develop the brain post-birth http://cyber.sci-hub.tw/MTAuMTAxNi9zMTA5NS02NDMzKDAzKTAwMDQ4LTU=/10.1016%40s1095-6433%2803%2900048-5.pdf …pic.twitter.com/SMFc6vUyOX

Smol brain: fat as insulator Literal big brain: fat as energy store
