Debunking Corner - The Top Ten Daily Consequences of Having Evolved

From here;


From hiccups to wisdom teeth, the evolution of homo sapiens has left behind some glaring, yet innately human, imperfections

Natural selection acts by winnowing the individuals of each generation, sometimes clumsily, as old parts and genes are co-opted for new roles. As a result, all species inhabit bodies imperfect for the lives they live. Our own bodies are worse off than most simply because of the many differences between the wilderness in which we evolved and the modern world in which we live. We feel the consequences every day. Here are ten.

1. Our cells are weird chimeras 
2. Hiccups 
3. Backaches 
4. Unsupported intestines 
5. Choking 
6. We're awfully cold in winter 
7. Goosebumps don't really help 
8. Our brains squeeze our teeth 
9. Obesity 
10 to 100. The list goes on. 
I have not even mentioned male nipples. I have said nothing of the blind spot in our eyes. Nor of the muscles some of use to wiggle our ears. We are full of the accumulated baggage of our idiosyncratic histories. The body is built on an old form, out of parts that once did very different things. So take a moment to pause and sit on your coccyx, the bone that was once a tail. Roll your ankles, each of which once connected a front leg to a paw. Revel not in who you are but who you were. It is, after all, amazing what evolution has made out of bits and pieces. Nor are we in any way alone or unique. Each plant, animal and fungus carries its own consequences of life's improvisational genius. So, long live the chimeras. In the meantime, if you will excuse me, I am going to rest my back.
