Good day from a new member.

Hi there, welcome

Thanks for sharing your story.

The explanation for morality through evolution is essentially very simple:

1) Our ancestors survived better when working together than acting alone. Organised hunting was efficient, as was protection from others.

2) Therefor, any slight deviations which caused us to "care" about our group and not just ourselves gave a survival advantage, and so more opportunity to reproduce.

3) Fast forward millions of generations, and natural selection would focus on and refine this "caring" to the point where it becomes full blown empathy.

4) Once you have empathy, hurting others is like hurting yourself, and so the natural inclination is not to do it.

PS: There are very good online essays here going into much more detail. (Not by me, but proper people.)

I also have links to many other resources on my website here.
