Animal Slavery

[John V]

As indicated in my last post, that it is pro-survival is a necessary but not sufficient condition to make something moral.

If biological factors are not sufficient to justify an action as moral, then they're not necessary for this discussion, which regards justifications.

What the other conditions which are also necessary is left unspecified, and at this time can only be grappled for with intuition and philosophy.

Which is what we were doing in the first place. This is the philosophy section after all.

Because evolutionary psychology and biological evolution operate at the level of species due to genetic compatibility.

This is off-topic, but anyway, you would need to support this. While some people do think that evolution can operate at the species level, some disagree, and no one to my knowledge thinks this is the only or typical unit of selection. Selection at the gene or individual level is generally thought to be more important, and groups may be the unit of selection in some cases.
