Why Is Body Hair Vestigial. Vestigial organs are body parts that have no or little function in modern humans, but are remnants of our evolutionary past. Learn about the appendix, wisdom teeth, body hair, and other possible vestigial organs, and how they challenge the theory of common descent. Humans still have the response of the arrector pili muscle pulling up the hair shaft, but we have no use for it, making it vestigial. Scientists have suggested three main explanations for why humans lack fur. All revolve around the idea that it may have been. Fluffing up hair or fur creates pockets to trap air and warm the body. Why we have significantly less body hair than most other mammals has long remained a mystery. In humans, the arrector pili—and their function when we’re cold or watching a scary movie—is a vestigial trait. As such, a common view is that now the body hair of men and women are purely vestigial, a useless evolutionary leftover from. It also can make the animal look bigger as protection against threatening creatures. It serves no purpose in our own species, but is there as an evolutionary remnant, for it has an adaptive function in our relatives, and did so in our ancestors.
