It's quite simple, dear Dane - race is a social term rather than a biological one. Don't be deluded by what your eyes see but, like that old cliche says, "it's the inside that matters".

The rejection of race and the rise of "population" and "cline"
At the beginning of the 20th century, anthropologists questioned, and eventually abandoned, the claim that biologically distinct races are isomorphic with distinct linguistic, cultural, and social groups. Then, the rise of population genetics led some mainstream evolutionary scientists in anthropology and biology to question the very validity of race as scientific concept describing an objectively real phenomenon. Those who came to reject the validity of the concept, race, did so for four reasons: empirical, definitional, the availability of alternative concepts, and ethical (Lieberman and Byrne 1993).
The first to challenge the concept of race on empirical grounds were anthropologists Franz Boas, who demonstrated phenotypic plasticity due to environmental factors (Boas 1912), and Ashley Montagu (1941, 1942), who relied on evidence from genetics. Zoologists Edward O. Wilson and W. Brown then challenged the concept from the perspective of general animal systematics, and further rejected the claim that "races" were equivalent to "subspecies" (Wilson and Brown 1953).
One of the crucial innovations in reconceptualizing genotypic and phenotypic variation was anthropologist C. Loring Brace's observation that such variations, insofar as it is affected by natural selection, migration, or genetic drift, are distributed along geographic gradations; these gradations are called "clines" (Brace 1964). This point called attention to a problem common to phenotypic-based descriptions of races (for example, those based on hair-texture and skin-color): they ignore a host of other similarities and difference (for example, blood type) that do not correlate highly with the markers for race. Thus, anthropologist Frank Livingstone conclusion that, since clines cross racial boundaries, "there are no races, only clines" (Livingstone 1962: 279). In 1964, biologists Paul Ehrlich and Holm pointed out cases where two or more clines are distributed discordantly -- for example, melanin is distributed in a decreasing pattern from the equator north and south; frequencies for the haplotype for beta-S hemoglobin, on the other hand, radiate out of specific geographical points in Africa (Ehrlich and Holm 1964). As anthropologists Leonard Lieberman and Fatimah Linda Jackson observe, "Discordant patterns of heterogeneity falsify any description of a population as if it were genotypically or even phenotypically homogeneous" (Lieverman and Jackson 1995).
Finally, geneticist Richard Lewontin, observing that 85 percent of human variation occurs within populations, and not between populations, argued that neither "race" nor "subspecies" were appropriate or useful ways to describe populations (Lewontin 1973). Some researchers report the variation between racial groups (measured by Sewall Wright's population structure statistic FST) accounts for as little as 5-7% of human genetic variation2. However, because of technical limitations of FST, many geneticists now believe that low FST values do not invalidate the suggestion that there might be different human races (Edwards, 2003).
These empirical challenges to the concept of race forced evolutionary sciences to reconsider their definition of race. Mid-century, anthropologist William Boyd defined race as:
a population which differs significantly from other populations in regard to the frequency of one or more of the genes it possesses. It is an arbitrary matter which, and how many, gene loci we choose to consider as a significant "constellation" (Boyd 1950)
Lieberman and Jackson (1994) have pointed out that "the weakness of this statement is that if one gene can distinguish races then the number of races is as numerous as the number of human couples reproducing." Moreover, anthropologist Stephen Molnar has suggest that the discordance of clines inevitably results in a multiplication of races that renders the concept itself useless (Molnar 1992).
Alongside empirical and conceptual problems with "race," following the Second World War evolutionary and social scientists were acutely aware of how beliefs about race had been used to justify discrimination, apartheid, slavery, and genocide. This questioning gained momentum in the 1960s during the U.S. civil rights movement and the emergence of numerous anti-colonial movements worldwide.
In the face of these issues, some evolutionary scientists have simply abandoned the concept of race in favor of "population." What distinguishes population from previous groupings of humans by race is that it refers to a breeding population (essential to genetic calculations) and not to a biological taxon. Other evolutionary scientists have abandoned the concept of race in favor of cline (meaning, how the frequency of a trait changes along a geographic gradient). (The concepts of population and cline are not, however, mutually exclusive and both are used by many evolutionary scientists.)
In the face of this rejection of race by evolutionary scientists, many social scientists have replaced the word race with the word "ethnicity" to refer to self-identifying groups based on beliefs in shared religion, nationality, or race. Moreover, they understood these shared beliefs to mean that religion, nationality, and race itself are social constructs and have no objective basis in the supernatural or natural realm (Gordon 1964).

Let's analyse the argument, nonetheless:
| quote: | The races have come to be through natural selection, and the reason why evolution didn't leave us all as one race is that for thousands of years human kind evolved in isolated groups with very little sexual intermingling taking place and under different circumstances imposed by nature (1).
Now, these groups did not only differ in the surroundings they lived in, they also differed in culture. Each culture imposes a specific valuation of some abilities (e.g. in some cultures, the ability to dance is highly valued, in others the ability to concentrate for long periods of time). This culturally imposed valuation means that some individuals are more successful in living within that culture than others, and hence are less prone to being outcast, suicide, and rejection by possible procreation partners (2). Hence, over time the treasured abilities of a culture will manifest itself in the population, whereas those that the culture rejects are eliminated (3). Thus, if subject X is of race Y, that allows one to have an expectation of the abilities of X, which is racism. (4) |
1: You see, you can't build a theory on something whose existence you can't prove now, can you? However, for discussion's sake, I'm replacing "race" for "nationality" in order not to stop here. These differences didn't necessarily appear out of natural selection, but rather could come out of temporary isolation and/or higher incidence of certain genes that don't play an important role in the environment that group of individuals live (e.g. Narrow eyes aren't useful for Native Brazilians - check my avatar -, even though their ancestors might've increased their chance of survival by having them in a windy/snowy region). Different individuals naturally don't agree 100% on anything, so there's no reason why two different nationalities would need to share all characteristics. That's why you've got different groups.
2: Such cultural/social "code of laws/needs" does exist, as can be seen even in the smallest communities (even here). Nothing to see here.
3: Not really. No culture is static and, thanks to those who don't fit into the cultural standards, it can be adapted. That's why there's xenophobia in rigid cultures.
4: Not true. An English-blooded person born in Cambodia, raised by Cambodian adoptive parents, won't be as different from a Cambodian (culture wise, physical needs wise, ...) as another Cambodian, so races don't really matter.
What does exist is ethnocentrism, in which a group perceives itself as superior to others based on subjective values.
