Humans have modified other species over generations by
and breeding individuals that possess desired
traits
.
Darwin proposed
selection
as the mechanism driving evolution.
Drug resistance in bacteria and viruses such as
HIV
are probably due to
and
for individual organisms that possess the resistance.
anatomical structures, such as the
among mammals, provide evidence of common
ancestry
with modifications.
Comparative
reveals
anatomical
not visible in adults.
Unrelated species that occupy similar ecological
may look similar by
evolution
.
Darwin's theory of evolution predicts
forms during the evolution of species, and this is supported by
records
.
Homologous characteristics derived from a common
can be used to establish evolutionary
relationships
among organisms.
