Race is better replaced by populations. Populations are groups of people who grew up in a region back when travel between regions was restricted enough that genetic differences appears. As our world become more connected, populations were grouped based on similar phenotype (not similar genotype) into races. Races do exist in that they are phenotypically similar groupings of population, but they have little value in comparison to populations at the biology level. Sociology level race has more importance because of how society reacted once those races were created (which also means it has an importance in the fields dealing with the history of science). And as the world becomes more globalized, the effects of populations decrease. It isn't gone and has a long way to go before it is gone, but as long as the world stays globalized it will happen. Far into the future, assume humanity achieves long distance space travel, it will likely result in new populations emerging and potentially even different species evolving. But that's so far away that it is best left to science fiction.
