some people have tried to use evolution to support racism. people wanting to justify racism claimed that certain groups, such as black people, were inferior. in nature, some animals do "survive" better than others, and it does lead to animals better adapted to their circumstances. with humans groups from different parts of the world, all evolution can say is that each group is probably well suited to its original situation. evolution makes no judgements about better or worse. it does "not" say that any human group is superior to any other.
