#9: We’re Animals At the End of the Day
The similarity in the number of hairs on the human body compared to chimpanzees is proof of our shared evolutionary history. While it may not be obvious, we humans indeed possess roughly the same density of hair follicles as our primate relatives. The key difference lies in the texture and length of the hair.
Human hair is considerably shorter and finer than that of chimpanzees, reflecting the changes that occurred during our evolution. This adaptation allowed our ancestors to better regulate body temperature through improved sweat gland function, a critical advantage in the hot savannas where early humans lived. So, while we may not be as visibly hairy as chimpanzees, the traces of our shared ancestry are still present.
