Without any of the /pol/ garbage, how have biologists convinced themselves that only there's only one species of an organism numbering in the 100s of billions, who have spent tens of thousands of years living in drastically different climates and environments.

It's not necessarily exclusive to black people, it's ridiculous to think that for example, Native Americans and Middle Easterns are the exact same despite all the thousands, if not millions of variables between the environment they adapt to.

It feels like if any animal had consistent differences in color, skeletal structure, and even chemical composition, we'd easily be separating them into groups.
