Following up on what the others said, I have to wonder what infant mortality rates were like for early human species. If, like Neanderthals and modern humans, there were species coexisting, probably mortality rates were similar given the time context.

We didn’t dramatically cut infant mortality worldwide until the 20th century or so for modern humans.

A big difference is the further back you go, you get a much larger birthing canal and babies carried in a longer term. So we have bigger, older, healthier babys being born easier, with less potential complications.

Yeah but think about how foul society was as it was forming. Population density without medical technology was what was so dangerous. Would be a good approach to look at tribal infant mortality (50% sounds high to me).
