Is race real or a socisl construct?

Although there is physical differences between Asian, African, European etc.. would you say there is strong biological evidence that there are different races or do you think it's a social (man made) idea to segregate humans into groups in order to create dominion over each other and so creates rascism? Do you think we can stop having races whilst still celebrating culture and history?
