There is only one type of human on earth!
How long till races vanish? Someone alive in 300 yrs has more than 1,000 ancestors alive today (assuming a roughly equal length of generation). If people continue to move and mix even on a modest scale, it is highly unlikely to meet a purely caucasian, asian, african or other being after a few hundered years.
Proud to stem from Charlemagne (approx. 747-814 AD), the famous ruler of Europe? In his generation everyone alive now has a theoretical 2 to the power of 50 ancestors, over a million times world population then. Everyone of European descent has a great many lines that make him/her descendant of Charlemagne.
There is one type of human on earth. All people living in the future, if any, will be common descendants. For conflicting parties, the thought might instill a desire to overcome their differences far enough to jointly secure the future.
Whether all intelligent beings that give rise to civilizations in the future are of human descent is a rather different question. What happens when machines surpass human cognitive power is rather unclear.
