“Assuming things are somewhat the same today there would be about 1500 murders in this world daily.”
Yikes! That’s one per minute - just under 1% of all deaths.
That may seem like a lot, but in hunter-gatherer societies of the type we all sprang from, death by homicide is close to 25% of total death rate.
No, I didn't "spring" from one of those, and you might want to ask your anthropology professor for a refund.
The darwinian view: answers for the gullible.
I doubt any of us could comprehend and absorb the stories of 1500 murders a day in our daily news. It would be an endless litany of woe leading to permanent depression for all.
