Evolution is fascinating, showing connections between all mammals, including humans. Evidence of our evolutionary past is found in early primates, Neanderthals, and modern Homo sapiens. A spectacular spot to see this evidence? “Our own bodies!”

Take goosebumps, for example. When our ancestors encountered cold, goosebumps increased surface area to retain heat. Today, this response only “tells us that we should have packed a coat.”

Another clear sign of evolution is found in our arms, specifically the palmaris longus tendon. This tendon, “linked to an ancient muscle,” has been phased out in over 10-15% of humans. To see if you have this tendon, place your forearm on a table, palm up, and lift your hand. A raised band in your wrist indicates its presence.

Whether you have this tendon or not, it provides a fascinating connection to our evolutionary past. These physical traits, even those appearing unimportant, offer profound insights into our history. “If that’s not evidence of evolution, what is?”
