Take, for instance, the curious phenomenon of goosebumps
This isn’t just a random occurrence. Our mammalian ancestors had a way of dealing with cold temperatures. Goosebumps helped them increase their surface area to retain heat. When we’re cold, a muscle attached to our arm hairs contracts, making the hairs stand upright and creating bumps on our skin.
While this response no longer serves a significant purpose in our lives today, it still reminds us to grab a coat on a chilly day. We can observe modern mammals engaging in this biological instinct, such as a pigeon puffing up its feathers to stay warm on a cold winter day. If that isn’t evidence of evolution, what is?
But there is one trait that clearly shows proof of evolution: The most compelling evidence lies within our arms, specifically in our tendons. One tendon, which has gradually phased out in 10-15% of the human population, highlights that humans are still evolving.
