Xia said, however, that other genetic changes may also play a part in losing tails. 不过,夏说,其他基因变化也可能是导致尾巴脱落的原因之一。 Another mystery: Did having no tails help these ape ancestors – and eventually, humans – survive? Or was it just a chance mutation in a populatio...

It's a commonly held belief that the origins of the human tail lie in the ancestors of humans. Scientists believe that humans eventually adapted out of needing tails and so no longer grow them. Some scientists, however, have recently speculated that vestigial tails are linked with abnormalities ...
So the claim by many evolutionists is that sometimes human babies are born with “perfectly formed, even functional tails” which are obvious ‘throwbacks’ to the tailed condition of their evolutionary ancestors.As alluded to earlier, they claim that the ‘vestigial’ genes for these tails ...
Millions of years after the ancestors of human beings evolved to lose their tails, a research team at Japan's Keid University have invented a robotic one that they say could help unsteady elderly people keep their balance.^{2}Dubbed Arque, a grey one-meter device tail, is similar to the...
How would Lamarck have explained the gradual shift from whales ancestors with front limbs to the whales of today that have fins? Why was it an evolutionary advantage for humans to lose the tails that monkeys have? If human genetic manipulation were possible, ...
根据倒数第三段的This could mean that our early ancestors developed consonant sounds while hanging around in the trees,too. "There's a growing sense that our dependency on trees was much larger and deeper than we think," says Lameira.(这可能意味着我们的早期祖先在树上闲逛时也学会了辅音。
Around 7 mya, a group of great apes known asHomininibranched off from the other great apes. This group contained the ancestors of humans together with the ancestors ofchimpanzees(our closest living relatives). Animals such asArdipithecus– a chimpanzee-like animal that lived around 5 million year...
This advanced motor skill enables orangutans make consonant-like sounds, argues Lameira. This could mean, that our early ancestors developed consonant sounds while hanging around in the trees, too. “ There’s a growing sense that our dependency on trees was much larger and deeper than we think...
