Hard to discern the implication

Fascinating.


Click for the thread.

This tweet in particular raises a question I am not sure I have ever considered.



If, in ancient times, half or more children died near birth, it introduces the idea of disjoint populations.

Today we expect, in developed nations, less than one in a hundred children born to die soon afterwards.

In Classical Greece, taking Aristotle at face value, 50 of one hundred die.

So my question is whether there is some systemic variance between those who die and those who survive? Or is it close to random selection?

More a thought exercise than anything else. It is hard to discern the implication, especially since the transition to low child mortality is so recent.
