Option D seems to be most relevant.Let's analyze the options:
A. Neanderthals only hunted in the forests, using thrusting spears - This doesn't guarantee the human intervention/ engagement in the incident.
B. At that time, only humans had developed projectile weapons - they might have developped projectile weapons but it
does not conclude that the person was killed by a fellow primate.C. The Neanderthal's wound was, in all likelihood caused by a thrown spear - other projectile weapons might also be responsible for the wound.
D. At that time only human beings had the type of weapon that would inflict this kind of wound - concentrates on the weapon
which could only be made by human beings back in that time. Correct optionE. Neanderthals and humans often came into contact with each other - so what.
Does not mean the Neanderthal male could be killed by a fello Neanderthal.
Hence, option D.
