APPENDIX TO LIFE
The appendix gets a bad rap. We think it’s a body part that can get affected and cause appendicitis. However, the appendix has good bacteria to get rid of the frenzied activity in the digestive system.
SUPERSIZED MOLECULES
Everything is pretty much made of molecules. However, the biggest molecules come from our chromosomes. Each cell has 23 pairs of chromosomes, which features a single, very long, molecule of DNA.
ATOM COUNT
Although these can’t be seen by the naked eye, adults are made up of 7 octillion atoms. Geez, that’s a big number!
FUR LOSS
While you may take this as a grain of salt, we actually have the same number of hairs on our bodies as a chimpanzee. Our hairs are so fine, that’s practically invisible. There isn’t much clue as to why we don’t have protected fur.
Some say it was to ward off ticks and lice or to sweat easily when moving into hotter territories. Like Russian foxes that ended being docile due to nurture, we’ve developed finer body hair and small mouths like an infantile ape.
GOOSEBUMP EVOLUTION
Interestingly enough, Goosepimples are a remnant of our evolutionary predecessors. For regular animals, it would be the tiny muscles around the base of each hair tense, pulling the hair more erect. As a result, the due would fluff up the coat and makes it a better insulator.
With a decent covering of fur, this would fluff up the coat. Also, that bristle feeling would be a way to look bigger and more dangerous.
However, our hairs are too fine to get that bulk effect. We just feel the sensation of our hair standing on end.
