>>13625974All animal eggs are pretty much the size of the baby they house, so a human egg would still need to be a huge, human baby sized egg. That would be almost twice the size of an ostrich egg.
Women already have difficulty birthing babies despite the baby being flexible. Now imagine giving birth to a rigid, giant egg.
The female pelvis would need to be much bigger.
But yeah, from an efficiency standpoint, laying an egg and not having to carry a baby for 9 months where you can't do almost anything productive would be much better.
