From what I've heard, we've run into the (semi-literal) bottleneck of infants having heads that just barely, or that don't, fit through a birth canal.

- paavoova 8y agoIf infants can develop brain mass in the womb, why can't they once born?
- TomMarius 8y agoBrain actually does develop until you're adult, but bones need to calcify and that limits how much it can grow

- culot 8y agoGrow babies in large jars, remove all cranial size limits.
- marsrover 8y agoThis actually happened to my wife. Our daughters head was too big to fit through the birth canal and when she came out (c-section) her head was in the 90th percentile for size. Looks like we can circumvent that bottleneck with modern medicine but then we run the risk of introducing new problems (faulty immune systems and risk to the mother for example)
