I never realized that so many body parts were obsolete! Tendons, wiggling ears, tails! I've heard of kids being born with tails. That's a little bit creepy. Apparently we all had tails at one point, that's why we still have tail bones. The tendon in the arm is interesting. I always thought it was a vein. Turns out it's there to help us swing from trees or something. You'd think I could do a pull up! Bet I could if I had a tail.
