What else can I help you with?
The structure of the forelimb of a bird is similar in structure to that of the forelimb of a mammal suggesting that both descended from a common ancestor What is this similarity an example of?
Homologous structures - the forelimb structures are anatomically similar and were derived from a common ancestor; however, they have evolved completely different uses. This provides evidence for divergent evolution or adaptive radiation.

What is a sentence using ancestor?
Example sentence - I discovered my ancestor was from England.
What does common ancestor mean?
AnswerA common ancestor means that two of more animlas are descended from the same individual. You and your second cousin have a common ancestor in one of your great grandparents; you and your sister have a common ancestor in you mother. AnswerIt means that the species involved evolved from the same ancestor. Contrary to popular belief, evolution does not follow a single path. It is more like a tree branching off in different directions. For example, the pterodactyl and modern birds both have a common ancestor in the archaeopteryx. Whereas each came from a pteranodon, they both evolved into different niches in the environment and thus developed differently.
Can you give an example of a sentence using the word ancestor?
My favorite ancestor came to my graduation ceremony!
Who is someone from whom you are a descendent?
someone from whom you are a descendant is called ancestor. Example: my ancestors built this country.
Name an ancestor of homo sapiens?
Homo sapiens have many ancestors. One likely ancestor, for example, is Homo heidelbergensis.
Does hopi ear candling stimulate wax production?
As vertebrates evolved, the same bones were sometimes put to different uses. Yet the bones are still seen, their presence betraying their evolutionary past. For example, the forelimbs of vertebrates are all homologous structures, that is, structures with different appearances and functions that all derived from the same body part in a common ancestor. You can see in figure 22.15 how the bones of the forelimb have been modified in different ways for different verterbates. Why should these very different structures be composed of the same bones? If evolution had not occurred, this would indeed be a riddle. But when we consider that all of these animals are descended from a common ancestor, it is easy to understand that natural selection has modified the same initial starting blocks to serve very different purposes.
Are all people who have descended from a common ancestor legal relatives?
Whether persons are "legally related" depends on the purpose for which the relationship is being measured, as well as the particular jurisdiction. For example, in New York the furthest relationship considered in the area of estates (intestacy in particular) is the first cousin once-removed. So, persons who are all descended from a particular person can all be legally related in some instances. But if the ancestor in question is further back than a great-grandparent, not each of the descendants is going to be a legal relation of each of the others (though some, of course, will be).
