Question

Can anybody explain what the principle of common descent is?

Answer 1

Well this term is new to me but, what i can see it is a group of organisms share common descent if they have a common ancestor.It arises during speciation, in which new species are established from a single ancestral population. Organisms which share a more recent common ancestor are more closely related.
