Sometimes evolutionary biologists have trouble determining if subpopulations of a group of organisms are a single speci or are unique species. African giraffes provide a good example of this. At least six distinct subpopulations of giraf exist, which include Rothschild's, reticulated, West African, Angolan, South African, and Masai. Each has a different pattern of spots on its fur and exists in a different geographi region in Africa. Three of the subpopulations have some overlap in Kenya and Tanzania. What criteria support the hypothesis that giraffes from different subpopulations are unique species? Giraffes from different subpopulations are unable to breed with cach other. Giraffes from different subpopulations face the same selection pressures. Giraffes from different subpopulations are not able to produce viable young. Giraffes from different subpopulations migrate betweem their home regions. Giraffes from different subpopulations experience similar patterns of genetic drift.
