It's about keeping yourself attached to the carer initially in your life, so that that carer is nearby and responds to your needs, because a newborn baby, an infant is helpless without a carer nearby.
And therefore crying is the evolutionary response to actually saying.
cement that attachment to your carer.
And then as time goes on, th this attachment idea continues, that it becomes part of
That comfort that you need from people who are close to you who are going to protect you.
And then as you get older, well, it may well be as simple as when you get older, there may not be an evolutionary reason for it.
It may just be a vestige of that early crying.
