I remember one of my first lectures in anatomy at uni, the lecturer was talking about the palmaris longus and how it was commonly used as a climbing muscle, but as we evolve further away from apes, fewer and fewer humans have this muscle as we just don't use it anymore. The lecturer said "so all you religious, creationist nuts out there - do this test to see if you have it or not, and try and tell me evolution isn't real HA-HA-HA" heaps forcefully![]()
