Document Summary

How does hiv cause aids? (immune system, t cells, patern of infecion) (p. 8) Why is hiv fatal? (short-sighted evoluion, collapse of immune system, new coreceptor) 32 allele and hiv resistance, regional diference. Adding selecion to hwe (change allele frequencies and genotype frequencies) Fruit ly adh locus (ethanol vs. control selecion) Selecion on recessive/dominant alleles (lour (soapberry bugs) (p. 40) beetles. Vesigial organs (kiwis, snakes, humans at structural, chicks developmental, cmah gene in humans molecular) (p. 42) Fossil record: exincion (irish elk), law of succession (armadillos), transiional forms (archaeopteryx, basilosaurus, ambulocetus) (p. 44) Age of earth, geologic imescale, radiometrics -60. Evoluion of lower colour in snapdragons (p. 78) Evoluion of beak shape in inches (p. 80) Natural selecion acts on individuals, but consequences occur in populaions. Ns acts of phenotypes, but evoluion consists of changes in allele frequencies. New traits can evolve, even though ns acts on exising traits (corn oil content, panda thumb) Natural selecion does not lead to perfecion (mosquito ish)
