Document Summary
Recall the human leukocyte antigen (hla) group or major. Section 1: essential facts and ideas about evolution. Phylogeny- a pattern of divergence of distinct evolving lineages from common ancestors. Formed on the basis of structural similarity or on the basis of similarities in early development or on the basis of similarities in dna sequences. Darwin"s finches underwent adaptive radiation into a variety of forms occupying ecological niches that wouldn"t normally be available to a finch (like the "vampire finch") Descent with modification was already being used to explain the gradual change in appearance of species in the fossil record before darwin revealed his theory. This variation may affect an individual"s ability to survive and reproduce. The circumstance in which natural selection may be expected to produce evolutionary change is when ecological demands change. Additive microevolution can lead to large evolutionary changes.
