What is the evolutionary advantage of a tail?

Tails are part of the evolutionary package for many mammals. For dogs and cats, tails help provide balance and offer an additional means of communication.

What are the advantages of a lack of a tail?

As it happens, the upright stance with no tail, which is good for moving in trees, is also good for leaving trees and walking on the ground. With a few adjustments, this enabled early humans to walk and jog over grassland and take up an entirely new way of life.

Why did humans evolve to lose tails?

As dogs show, tails are useful for visual communication, slapping away flying insects and other functions. Adult apes, including human ancestors, took the tail loss process a step further, Sallan said, “losing the remaining bony tail for better upright movement.

Why do you think it was evolutionarily advantageous for apes and humans to lose their tails?

As such, the loss of the tail can be seen as an adaptation to a particular environment, which allowed our ape ancestors to leave trees and walk on the ground. With some adjustments, early humans could not only walk but jog over the grassland.

What would happen if humans had tails?

Tails would play a role in how humans maintained balance, depending on how long they were. In addition to the regular vulnerabilities, there is the added danger of someone being able to grab the tail and deliver serious pain and harm by disjointing it. It would be similar to having a finger broken.

Would humans benefit from a tail?

No, tails have no purpose in modern humans today.

What evolutionary change led to modern humans having back sore or back problems?

The identification of an ancestral vertebral shape that influences the occurrence of a common spinal disease in humans also supports the idea that the relatively quick evolution of bipedalism may have had a substantial impact on modern human health.

What’s the purpose of tails?

Many land animals use their tails to brush away flies and other biting insects. Some species, including cats and kangaroos, use their tails for balance; and some, such as monkeys and opossums, have what are known as prehensile tails, which are adapted to allow them to grasp tree branches.
