So my friend says that....

[tump13b]

2 of my friends say that in 200 years all the races will have mixed into one race.

They think that since now people can get around the world so much easier that in 200 years, which is roughly 8 generations everybody would have mixed and there won't be seperate races anymore but just one race.

Can someone help me out and say that this is complete BS?

Thanks haha

Well I mean the actual sums for this are quite confusing (for me, at least), but your friend's 'BS' assumes random mixing and that travel makes the human population heterogenous.

Which it isn't and doesn't, of course.
