Race: Biological Reality or Social Construct?

Race was once thought to be a real biological kind. Today the dominant view is that objective biological races don't exist. I challenge the trend to reject the biological reality of race by arguing that cladism (a school of classification that individuates taxa by appeal to common ancestry) provides a new way to define race biologically. I also reconcile the proposed biological conception with constructivist theories about race. Most constructivists assume that biological realism and social constructivism are incompatible views about race; I argue that the two conceptions can be compatible.
