Document Summary
40 mc - class, text - 15-point short answer from class material ch 1-3 + introduction. Darwin- confronted lots of variation; no idea of its source. Darwinian evolutionary theory- competition for scarce resources (survival of the fittest) Egg came before the chicken: hen = protoplasmic superstructure that allows for the production of another egg. Fitness doesn"t really matter because if you do not reproduce you are not being included into the new gene pool (not carrying genes to the next generation) The egg is the only answer in relative to darwin but chicken is just the transfer of the genes. A"s genes cannot get into b"s pool different species) Example a= cats and b= dogs, a cannot be in b also. (two. Mule is a non-overlapping strain because is cannot reproduce. A"s genes can get into b"s pool- hybridization. Mut different strains = breeds of dogs.
