In the context of biology or ecology, a "population" is defined as being a collection of organisms of the same species

A species is a collection of organisms of the same species.

A family is a collection of organisms of the same species (although I have my doubts about that aunt...)

Your point is not clear to me.

If you define a species as the set of all such organisms, then a "population" is a subset of that set.

And a set is a subset of itself.

I don't really see where you are going with this. Yes, all the members of a species could qualify as being a "population" - expecially if they all lived in the same place.

However, that doesn't make species selection into a special case of group selection under the Wikipedia definition.
