|
Species A & B do not share a common ancestor
|
|
|
Species A is younger than species B
|
|
|
Species A & B share a common ancestor
|
|
|
Species A evolved independently of species B for a long period
|
Detailed explanation-1: -If species A and B have very similar genes and proteins, what is probably true? (A) Species A and B shared relatively recent common ancestor .
Detailed explanation-2: -These shared genes are evidence of evolution from a common ancestor and the relatedness of all life on Earth. The shared genes are called homologous genes, or genes which share a common ancestry either between or within species.
Detailed explanation-3: -They found that while many proteins are similarly variable both across and within species, some are more variable between species, providing clues about which proteins might be more important in mammalian evolution. The work may also help researchers understand why some species are more resistant to cancer.
Detailed explanation-4: -Species is a group of organisms that are similar and can reproduce among them selves.It is the smallest unit of classification.All human beings belong to one species. A gene is a unit of heredity.Parents pass on genes to their children.Genes control all charecetrs of an individual.
