Recently, researchers uncovered a genetic clue about why humans have no tails. They identified a so-called jumping gene related to tail growth that may have leaped into a different location in the genome of a primate species millions of years ago. And in doing so, it created a mutation that took our tails away.
Why did humans evolve to not have tails?
The researchers hypothesize that 20 million years ago, a random human ancestor was struck by the TBXT gene mutation and passed the tailless trait to its offspring for several generations. Eventually, humans evolved with this mutation which is why we don't have tails.
Around 25 million years ago, our ancestors lost their tails. Now geneticists may have found the exact mutation that prevents apes like us growing tails – and if they are right, this loss happened suddenly rather than tails gradually shrinking.
