Document Summary
Without speciation, there would be no tree of life. There is no consensus regarding which species concept is the best. None are perfect, each have their own problems. Why does it matter whether two populations are one species, or two: african elephant and asian elephant are two, different species. One is smaller, ear shape is different. Other cases it can more arbitrary: other than the african elephant, another type of elephant species live in. Not very widespread, live in congo and surrounding areas. Body is smaller, tusks are shorter and different color. Live in small families, compared to large herds. Live in forest, compared to african elephant which lives in open areas: both elephants considered members of same species. Therefore there was no special conversation status for these smaller elephants. African elephants were not endangered, but the other kind was. When we considered both of these the same species, they were not considered endangered.
