BIO 322 Exam 1 Questions and 100% Correct Answers

If chimpanzee and human genomes differ only about 1.3% at the level of DNA base pairs, how can we explain dramatic differences in appearance, behavior, cultures, and so on between humans and chimps?Important difference exist in the expression of the genes in the humans and chimps The primary process responsible for the adaptive modifications that occur in populations of organisms over geological time isNatural Selection The wing-ed-ness of a bat wing and hummingbird wing are probably products ofconvergent evolution Synapomorphies are very important traits in phylogeny inference. Which of the following statements is correct?Synapomorphies are derived traits inherited from a common ancestor. AND Synapomorphies help identify monophyletic groups. The uses of phylogenies include all EXECPT?Showing natural selection in action Phylogenetic conservatism isProbably the result of complex systems of genetic expression becoming coadapted and so imburdened as to prevent subsequent mutations that would change conservative features from being beneficial Which source(s) of data do evolutionary biologist use to test their hypothesis?Molecular data, Morphological and behavior data, Data from the fossil record. (all are correct) Darwin's hypothesis of common ancestry with branching descent explainsThe history and patterns of life's diversity, the hierarchical patterns of similarity observed in nature, varieties need within species, nesting within genera (all are correct) Considering the phylogenetic evidence that feathers evolved prior to flight, what might have been the original function of feathers?Facilitating tactile sensation, waterproofing, heat reaction, shielding from sunlight. (all of these are possible functions) How can we explain the exquisite complexity of some complex traits, such as the vertebrate eye?Intermediate stages of complex traits were functional and selected
