That is co-evolution.
Of the 17 known species of penguins, only two of them actually breed on Antarctica. For more information, see the related link.
There are many more than two species related to the kangaroo. The kangaroo family comprises over 60 members, including the following species:wallabywallaroopotoroorat-kangaroo (not kangaroo rat)bettongquokka
It is called symbiosis. For more information about symbiosis, see the Related Links.
Evolutionary relationships are traced in the classification of organisms. For classification of organisms, we look for similarities among organisms which allows us to group them. The more characteristics two species will have in common, the more closely they are related. It indicates that more closely two species are related, the more recently they would have had a common ancestor. Thus, classification of species is in fact a reflection of their evolutionary relationship.

No. Yoshis and Birdos are two completely different species.
it means the species shared a common ancestor in the recent past
A factor that tends to cause species to change can be one of two things. It can be either climate change or an invasive species.
ancestors
The description of synapomorphies (A derived trait shared by two or more species that is believed to reflect their shared ancestry) is important in the work of systematics (taxonomy) because then the systematists can know how the two or more species is related.
Same genus or closely related species.
