Projectile weapon injuries in the Riparo
Tagliente burial (Veneto, Italy) provide
early evidence of Late Upper Paleolithic
intergroup conflict
The dates are too young - 17Kya to 15.5kya - for
the neanderthal scenario but old enough to suggest
warfare, raids, etc. Neanderthals may not have
had the reproductive replacement capcacity to
compensate for population losses. In such conflicts
it not unusual for the women of attacked groups
to be taken alive which could explain admixture
of genes.
