Will you ever evolve to have tails again?In: Human Anatomy [Edit categories] |
[Edit] |
Answer
It is unlikely that humans will ever evolve tails again. Tails help to improve the balance of primates using an above-branch climbing locomotion, and other animals using quadrupedal locomotion techniques. Given that we're bipedal and are likely selected to remain so, it is unlikely that we'll re-evolve a tail unless the environment that we're adapting to changes dramatically. Even if the genes controlling the growth of a tail were to mutate, it would take the additive effects of more than a single mutation to cause a human to have a tail again, and so such genetic changes would likely be lost before they were even observed.
