There are many different species of mostly the same animal… That differ only in the slightest details…
But humans despite evolving separately for a very long time are still the same species regardless of the race.
In: Biology
Species are usually defined as organisms that could breed and positive viable offspring that can itself procreate. Humans can obviously do that despite our differences, so we’re definitely the same species.
However, it can get tricky. Horses and donkeys can produce mules that are sometimes fertile. On the other end, some species are genetically perfectly able to procreate, but don’t with certain members who have different pigmentation out different mating calls (eg grasshoppers). If they could breed but don’t, are they the same species? I guess it depends on how you want to define the term and for what purpose.
