This brings to mind an interesting passage from _tribes of
california_, by powers. He had the impression that there was a
preponderance of girls among the children of whites and indians in
california. Could that be evidence of limited fertility for white-
indian hybrids? If so, that would be the only evidence I know of
indicating sufficient genetic distance between human races to approach
a speciation event.

(Note: male fetuses are less developmentally robust, and are subject
to higher rates of spontaneous abortion in adverse conditions.)
