Darwin and Evolution Irelyn anderson
EVIDENCE OF EVOLUTION
A birds wing and a horses front limb have different functions but similar structures.
They see inherited from ancestors but have lost all of there functions due to different selection pressures acting on the organism.
Researchers noticed that early developmental stages of many animals with backbones look very similar. The same groups of embryonic cells develop in the same order and patterns to produce the homologous tissues in organisms.
LIFES COMMON GENETIC CODE
Evolution is so basic that by this point the study of evolution might take it for granted. All living cells use DNA and RNA to carry information from one generation to another to direct protein synthesis.
