Humans aren’t particularly good at hurting each other when unarmed. No claws, or anything to use as a weapon.

For thousands of years we’ve specialized and advanced ways of using our bodies natural strengths and weaknesses to defend or attack each other.

Hypothetically, if there are aliens that are ‘big brain’ fragile body types, like us, would they have tried to master ‘hand to hand’ combat?
