Once again, facts that are plain as the nose on your face to us are major new discoveries to liberals.
I wonder how much money these people make for concluding the obvious. Sounds like a great gig.
Cain killed Able and had offspring to spread his DNA. Able, no so much so. Oh, and I need $100,000 in grant money for arriving at that conclusion.
Our prehistoric ancestors were as violent as humans today
This subject has been controversial. The long childhood of humans has reduced species intra tribal violence. However, inter tribal violence seems more prevalent than many other species. Monogamy has benefits within a tribe reducing competition for females.
They were?? Wow, these people are brilliant...for idiots.
The only thing that has changed, people can be killed much faster and en masse.
Let's hope that doesn't become a thing.
The whole thing was covered in Genesis.

Well, of course they were, and we have film evidence to prove it!
And Cain talked with Abel his brother: and it came to pass, when they were in the field, that Cain rose up against Abel his brother, and slew him.
Genesis 4:8
The earth also was corrupt before God, and the earth was filled with violence.
Genesis 6:11
Gather unto me all the elders of your tribes, and your officers, that I may speak these words in their ears, and call heaven and earth to record against them. / For I know that after my death ye will utterly corrupt yourselves, and turn aside from the way which I have commanded you; and evil will befall you in the latter days; because ye will do evil in the sight of the LORD, to provoke him to anger through the work of your hands.
Deuteronomy 31:28-29, Moses speaking
It is widely acknowledged that monopolisation of the legitimate use of violence by the state significantly decreases violence in state societies, the paper explains.
Studies of modern hunter gatherer societies and ones in the past century showed MUCH higher murder rates, 10-30X that of civilized society.
The myth of the noble, peaceful savage is just that - a myth.
Fifty five years ago I read of an archeological dig in which they unearthed the skeleton of a prehistoric man. Firmly lodged in the backbone was a flint spear tip.
Yeah! A bit part of the “Leftist meme” was that man was inherently good if left to their own devices, ignoring the fact that civilization has to be pounded into most people.
American Indian peace and harmony here!

“The scalping victims considered in this study came from the Southeast, the Midwest, and the Southwest.
The Midwest is by far the region with the largest sample, estimated at between 400 and 500 scalped individuals. However, most of these victims came from Crow Creek Canyon, the site of a large-scale massacre involving a minimum of 486 individuals (Gregg et al 1981).
The excavators report that not only were almost every person scalped, but they also were mutilated and dismembered, and many of their hands and feet appear to have been removed and taken as trophies.”

Interesting mention of the taking of hands and feet as trophies. In Burke’s book ON THE BORDER WITH CROOK he mentions how they the troops and their Shoshone allies had attacked a hostile Cheyenne camp, and in that camp they found a bag of hands cut from Shoshone babies.
The Shoshone allies took the bag, and spent the entire night weeping and wailing over it.
Try "Original Sin". You can read all about it in the "Book of Genesis".
I’ve often said that war is man’s natural state, and that peace is only the exception that proves the rule.
History is little more than a study of mankind’s repeated conflicts.
Who are you going to believe, a guy wearing make-up and lacy drawers sitting around sipping wine or the evidence of your lying eyes?
I always wondered why anyone with two brain cells to rub together took Rousseau seriously.
