Biology

GREYUIT [131]3 years ago

Well, to know the answer to this question, you must know the meaning of vertebrae. Vertebrae are just a connections of bones that make up your backbone. These include about 24 ligaments that make up your spine. So all vertebrae are bones since they are ligaments and other bones that make up, well, your backbone! However, not all bones are vertebrae, because your finger bones, ribs, skull, and other bones in your body aren't part of your backbone.

Hope this helps!

How did the artificial selection practiced by pigeon breeders influence Darwin's theory of evolution by natural selection?
ololo11 [35]

The study of artificial selection by Darwin helped him to establish his theory of evolution via natural selection. One of the animals Darwin examined in detail was the domestic rock pigeon. In the 1850s breeding of pigeons was an ancient past time, thus, Darwin decided to keep and breed the pigeons by himself.  

While studying pigeons, Darwin established scrupulous determinations of their skeletons and wondered at the breeds' distinct colors, behaviors, and proportions. He also observed the patterns of inheritance of various features, and he demonstrated that birds of very distinct breeds can, however, generate fertile offspring. Thus, supporting the theory that they all originated from a single species.

As such they resemble south American anteaters and hedgehogs but are not closely related to them. Instead echidnas descended from an aquatic platypus like ancestor.
