      Not species, genes. Species is a socially constructed concept. Selection operates at the level of individual genes which are the fundamental transmissible units.

      Bacteria even carry out horizontal gene transfer via the exchange of plasmids between cells!

      I wonder if decreased reproduction in developed countries is the result of evolutionary forces from long ago. It seems like most animals are the opposite, and have more offspring during times of plenty.
