This is Scientific American - 60 Second Science. I'm Dylan *. Got a minute? The first murder victim in the Bible is Abel, taken out by his brother, Cain. And now we have what looks to be the earliest known homocide to be confirmed by scientists. A new study concludes that human remains¹ found in an archaeological site in northern Spain are from someone bludgeoned to death about 430,000 years ago. The findings are in the journal Plus One. The researchers piece together 52 skull² fragments found in an underground cave. Two holes above the left socket³ are especially diagnostic. A blow that would create either hole would probably be deadly. And the lack of any signs of healing around the holes implies either that the impcats were lethal⁴ or occured after death. The absence of any cut marks on the skull helps rule out postmortem canniablism, a ritual that could cause the observed damage. The dicovery of the body in a cave could mean that the victim was moved there. The find would thus be evidence of ancient burial practices. Unless the murderer was just hiding the body. This exceedingly cold-case crime scene investigation⁵ shows that even before the emergence⁶ of modern humans some 200,000 years ago. Volence and murder were a part of life. The perpetrator's remains remain at large. Thanks for the minute for Scientific American - 60 Second Science. I'm Dylan *.
