Not only is what you say correct, but from a biological/scientific point of view race does not exist.
In fact there is as much genetic variety within a “race” as there is between races.
There are obvious differences (skin color being most readily apparent, but there are others – eye shape & other facial features, for example) but these are very superficial (like eye or hair color within a race), leading to race as a social construct with no significant scientific basis.
Do your own search to find many articles such as:
Long established scientific fact is that all human beings originated from one area of the world (Africa as it is now known) which means we ALL have the same ancestry. Only those moving to latitudes further from direct sun lost melanin to become “white”.
There is really only one race – the Human Race…
