Document Summary
Descent with modification: a darwinian view of life (ch. 22: what is evolution and adaptation (2 main ideas, evolution: two main ideas, change over time of the genetic composition of a population, decent of modern organisms with modification from preexisting organisms, evolutionary adaptation. Accumulation of inherited characteristics that enhance organisms ability: pre-darwinian theory of evolution to survive in specific environments, lamarck (turned out to be wrong) Use and disuse: bodies of living organisms are modified through the use of disuse of parts. Inheritance of acquired characteristics: evolution by natural selection, these modifications are inherited by offspring, darwin and wallace developed the theory independently. 2: within a few weeks of treatment_____ drug 3tc a patients hiv population consists entirely of 3 tc-resistant viruses. Figure 22. 15: homologous structures: vertebrate embryos, all vertebrates share similar developmental genes. 3: differences arise by some genes being switched on or off at varying times during development(figure.
