How our ape ancestors suddenly lost their tails 25 million years …
2021年9月24日 · 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...
Ape - Wikipedia
Unlike most monkeys, apes do not possess a tail. Monkeys are more likely to be in trees and use their tails for balance. While the great apes are considerably larger than monkeys, gibbons (lesser apes) are smaller than some monkeys. Apes are considered to be more intelligent than monkeys, which are considered to have more primitive brains. [36]
A genetic parasite may explain why humans and other apes lack tails
2024年2月28日 · A new study suggests that apes, including chimpanzees and humans, lack tails because a genetic parasite altered a gene important for tail development when the group diverged from other...
Why Don't Humans Have Tails? | Smithsonian
2024年3月6日 · Scientists have long suspected that apes evolved their upright posture and bipedal movement in part because they no longer had tails, per the new study. Walking upright, in turn, could have...
On the genetic basis of tail-loss evolution in humans and apes
2024年2月28日 · An insertion of an Alu element into an intron of the TBXT gene is identified as a genetic mechanism of tail-loss evolution in humans and apes, with implications for human health today.
Losing their tails provided our ape ancestors with an evolutionary ...
2024年3月3日 · Tail loss occurred in our ape ancestors at the same time as the evolution of a more erect back and, in turn, a tendency to use only two of the four limbs to support the body.
Why don't humans have tails? A genetic mutation offers clues
Somewhere around 20 million or 25 million years ago, when apes diverged from monkeys, our branch of the tree of life shed its tail. From Darwin’s time, scientists have wondered why — and how — this happened. Now, researchers have identified at least one of the key genetic tweaks that led to this change.

How humans lost their tails — and why the discovery took 2.5
2024年2月28日 · Unlike most monkeys, apes — including humans — and their close extinct relatives don’t have tails. Their coccyx, or tailbone, is a vestige of the vertebrae that constitute a tail in other ...
A mobile DNA sequence could explain tail loss in humans and apes …
2024年2月28日 · Insertion of a short DNA sequence into a gene that controls tail development could explain tail loss in the common ancestor of apes. An alternatively spliced gene contributed to tail loss...
