There is a risk here of confusing the biological sense of “human” as an taxonomic term (like “canine” or “simian”) and the word’s normative use, as in “human rights”. In the biological sense, ‘human’ refers to the biological species homo sapiens and to be human is to be a member of this biological species. In the evaluative sense, ‘human’ refers to a property that is the basis for having certain moral rights and a particular kind of moral value. Obviously it is not enough to be biologically human to enjoy human rights: human tissue cultures and human cadavers show us that. Is it even necessary to be biologically human to enjoy what we call human rights? There are many candidates for the natural qualities that are the basis for moral rights, but none hinge on a biological designation. So why is it that interventions that “alter the species” “might cause the affected children to be deprived of their human rights”?
