Its hard to imagine that our large brain came first and the birth canal was an afterthought :))
As the case with dolphins, humans rely on social interactions to survive. The more an animal relies on their caregiver, the more it relies on learning and the less it relies on instincts to survive.
- Sharlin 9y agoThe point is that the pelvis (and birth canal) size couldn't keep up with the increase in cranium size, possibly due to other selection pressures like the requirements of bipedal gait. Human females would need ludicrous hips if we were born more developed.
