Which statement describes an effect of natural
selection on a species?
(1) it favors the survival of certain members
of the species and results in a change in
the proportion of individuals with highly
adaptive traits.
(2) it provides feedback mechanisms for members
of a species and results in a change in the
proportion of individuals with homeostatic
controls.
(3) it leads to reproduction with other species,
increasing the number of different adaptations.
(4) it increases competition between populations
that occupy different niches, increasing the
chance of extinction of the less-adapted
