Depends on the age, sex and species of these two generally-named animals.
No. Generally, one species gives rise to two new species by geographic and reproductive isolation. Separate species mating at best gives nonviable hybrids.
Yes, he has two sisters.
Two organisms belong to the same species even if they are seperated by a geographical barrier, as long as they can mate and produce fertile offspring!
True owls are one of the two generally accepted families of owls - the other being "barn owls". The barn-owls' main characteristic is the heart-shaped faces. True owls tend to have large heads, short tails, cryptic plumage.and round facial discs around the eyes. They also differ from the barn owls in structural details relating in particular to the sternum and feet. The toes and tarsi of true owls are feathered in some species, and more so in species at higher latitudes
Through evolution. There are two main kinds of evolution which are gradualism and punctuated equilibrium. In gradualism, natural selection slowly removes unfavorable traits for the environment that the species is living in. After many years the different habitats will result in two species. This same theory is true for punctuated equilibrium except that in p.e. there is a sudden burst of change followed by a dormant state of evolution for the species.
