Member of the human species.

It's morally relevant because we say it is. Everyone believes it's morally
relevant, including you, questioning it is simply disinformation.

There is only one definition.

A few animals lack the inherent abilities of other members of their species,
they are still members of that species. Failure to possess the qualities of
one's species is ad hoc, arbitrary or accidental, not a logical approach.
The proper measure is qualities which members of a species possess by
default, not qualities which rare individuals are missing.

That's a perverse view which nobody actually holds. Even ARAs and vegans
dismiss whole species of animals based on dissimilarity to humans.
