Question

3. Do you think that group selection affects evolution of natural populations? Why or why not? Your answer should use the JM Smith and/or Kerr et al papers that we discussed in class.

Answer 1

Group selection is a phenomenon in which one of the individuals group evolve into ne w group different from other group or the group containing the mutant type may be die out in the course of evolution. Group selection is a process in which one individuals look out for the rest of offspring’s in the group for any predators threat at the expense of its own energy to raise the offspring’s. In the due course as the healthy offspring’s survival rate is higher the deleterious mutant type are eliminated and pure phenotypes offspring are survived while the harmful genotypes are removed from the group leading to evolution where new phenotypes is evolved from healthy population with removal of mutant genes.

Group selection promote the evolution as naturally fit organisms are evolved and survived minute changes at the alleles are observed called as microevolution.
