What is the science that explains why the issue of an interracial union is able to live?

Question

I am finishing my bachelor's degree and need some help in finding reference material for a report.

I am very surprised that the issue of interracial unions aren't stillborn but this alone supports the hypothesis that regardless of race we are all the same species.

With that said other than interracial issue living what scientific proof supports the idea that the other two races are just as "human" as the human race (Caucasian)?

I have to do a report for my class on the 3 races of man and I want to explain that the ***** and Oriental races are the same species as the human race.

Hmm, good question! Try an anthropology book.

EDIT: LOL, the Jungle Book:)
