My analysis: The average caveman had to be alert to guard against predators. the women could sit by the fire and chat, knowing they were protected.
The hairy cavemen said: 'Kill! Lion! Kill Tiger! Kill Bear!
The women around the fire said: 'I love your garlic necklace dear, and the way you do your hair...we have plenty of food this year, here have some more dried deer, and how has Grong been treating you, hmmm?
After the threads we've been on, I thought it was time for some humor! ;o)
Oh baloney...after the lions and tigers and bears ate the men folk...then women killed the lions, tigers, and bears and served them up in a gamey souffle...with a nice chianti and fava beans.
