Scientists have long wondered what killed the Neanderthals off. They were bigger than us, had larger brains, and existed in the same places and times as we did, but they died out and we survived. Additionally, there appears to have been little, if any, inter-marriage between us and them. No one knows why, but today, I figured it out.
It came to me because I was doing yardwork. Its a murderously hot day and I’d been out in the hottest part of it cutting grass, trimming bushes, etc. Normally, I don’t sweat much no matter how hot I get, but today, the sweat was just pouring off of me in buckets, getting in my eyes and blinding me.
After nearly slicing my leg off, I went into the house in search of a towel to wipe the sweat off my face so I could see. As I was doing so, I grumbled to myself about why hadn’t we evolved something so that sweat didn’t get into our eyes. Because after all, if you’re in a fight for your life and you can’t see, you’re probably not going to live long enough to pass on your genes. Then, as I stared at myself in the mirror, I remembered that part of the purpose for the brow ridge was to divert sweat from our eyes. So I thought, “Why don’t we have a bigger one?” Then I remembered that the Neanderthals had a larger one. That’s when it hit me!
Larger brow ridge = more sweat. More sweat = more stench. So, by comparison, we humans, no matter how stinky we got must have smelled better than our Neanderthal cousins. It would have also taken less effort for us to clean the stench off of ourselves, thus enabling us to devote more time for things like making babies. Plus, a Neanderthal must have reeked like a dead mule, making it easy for his/her enemies to find them.
This also explains why we rarely intermingled. They smelled bad, so we didn’t want to have anything to do with them.
Of course, since I thought all of this up without the help of a PhD, I’ll never see any Nobel Prizes for it, and knowing my luck, someone will come along with a two sentence post that totally demolishes my theory, but I thought I’d post it so I could bask in the glory of my idea for a few moments.
