Document Summary
Beak size and robusticity: peppered moths, antibiotic resistance, multidrug-resistant tuberculosis (mdr tb, methicillin-resistant staphylococcus aureus (mrsa, ex: when penicillin became available during wwii it was considered a medical miracle. Evolution (changes in allele frequencies: production and distribution of genetic variation, natural selection. Microevolution small scale adaptive changes within a population found below the species level. Macroevolution large scale adaptive changes within a population found above the species level. Deme (population community of individuals from which mates are selected share gene pool all the genetic population. Hardy-weinberg equilibrium: predicts allele distribution in a population under ideal conditions ideal conditions: large population everyone has equal opportunities to find a mate, no genetic mutations. Influences on allele frequencies: mutations- a change in the dna sequence, naturally occurring mutations and induced. Approximately 5 substitutions per billion nucleotides per year. Decrease in genetic diversity: founder effect- a small number of individuals separate themselves out of a large population they start a new colony.
