Document Summary
Descent with modification: a darwinian view of life. How can we change this race to reflect the process of natural selection: have a tiger chase them, pair the fastest men with the fastest women. 1:44 pm: analogous to natural selection, concept 22. 3 evolution is supported by an overwhelming amount of scientific evidence. Selective breeding of organisms to encourage the occurrence of desirable traits. 22. 13: within a few weeks of treatment w/ 3tc, a patient"s hiv population consists almost entirely of 3tc resistant viruses. How can this be explained: a few drug resistant viruses were present at the start of treatment and natural selection increased in frequency, exhibits mechanism of natural selection, natural selection and hiv resistance. Fossil record: show change in organisms through time, change in types of organisms, past organisms differ from present-day organisms, many species have become extinct, organisms found in def. time periods are very different.
