What are the dangers in the Paleolithic?

Other cavemen, volcanoes, poisoned crops, and dangerous animals such as the armadillo (Used to be a ferocious carnivore) and dangerous sea creatures (sharks).

More to the point, disease & accidents.

Dangerous animals? Yes as they were hunters, but quite where the reference to armadillos and their supposed past comes form, I cannot imagine! Sharks?

Perhaps, but not very likely and only a threat to those living on coasts whose waters are home to the dangerous species.

Volcanoes? Maybe, but only to those living near active volcanoes!

Other "cavemen"? Probably only a very few Palaeolithic people lived in caves, because caves suitable for habitation are fairly rare, but we can surmise with no supporting evidence that these people could have been as quarrelsome as humans are now!
