Classification of living things PPT, part three: species and varieties

Horses are divided into wild horses and domestic horses, and domestic horses and many breeds of horses. So, do they all belong to the same species?

A species is a group that shares a common gene pool and is reproductively isolated from other groups. This definition takes the presence or absence of genetic exchange as the main basis for classifying species. Many species of livestock, poultry, and cultivated plants, although morphologically distinct, can interbreed and are therefore merely different varieties of one species.
