Does "atomized selves in thrall to our self-interest" mean "Does "selves that are atomized and servile to our self-interest"?

Context:

Clearly, our selfish and selfless interests do not always conflict. In fact, the well-
being of others, especially those closest to us, is one of our primary (and, indeed, most selfish) interests. While much remains to be understood about the biology of our moral impulses, kin selection, reciprocal altruism, and sexual selection explain how we have evolved to be, not merely atomized selves in thrall to our self-interest, but social selves disposed to serve a common interest with others.
