Document Summary
Descent with modification: darwinian view of life: evolution: 2 main ideas. I: 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 to survive in specific environment. Pre-darwinian theory of evolution: lamarck, use & disuse, bodies of living organisms are modified through the use or disuse of parts (giraffe picture) Inheritance of acquired characteristics: these modification are inherited by offspring, these ideas turned out to be wrong. Individuals in a population vary in their heritable characteristics a: organisms produce more offspring than the environment can support. Individuals that are well suited to their environment tend to leave more offspring than other individuals: over time, favorable traits accumulate in the population. How can this be explained: a few drug resistant viruses were present at the start of treatment and natural selection increased their frequency.
