20. The theory of natural selection does not depend A Heritability B. Purpose C. Reproductive success 21. Phylogeny illestrates A Common ancestry. B. Genetic drift. D. Variation C. Natural selection 2. Which of the following is an example of a convergent trait? The shared five-digit character state in tetrapod vertebrates The multiple hemoglobin genes in the jawed vertebrates The triangular dorsal fin in sharks and dolphins All the above would be considered convergent traits. D. Particulate inheritance. Phylogenetic trees may be used to display relationships among which of the following C. Species D. All the above B. Genes Cells Characters are referred to as being homologous if They evolved independently in two taxa because of a common environment. They were acquired through horizontal gene transfer. They are similar because they were inherited from a shared ancestor They evolved as the result of a gene duplication event.

According to the theory of natural selection, A. adaptations beneficial in one habitat should generally be beneficial in all other habitats. B. different individuals occupying the same habitat will adapt to that habitat through the same genetic changes. C adaptations beneficial at one time should generally be beneficial during all other times.
