Document Summary
Slide 1: orchid from madagascar & moth with exceptionally long proboscis: mutualism between the two organism, co-evolution, co-adaptation ! Slide 4: key terms & de nition: tness (also called darwinian tness):! An individual"s relative genetic contribution to the next generation as a result of variability and fertility differences: selective advantage! Some individuals are better at adapting to the environment, thus have a higher. Tness, and able to pass on more genes: adaptation! Noun: any trait that makes an individual tter, and better at surviving and reproducing in a given environment! Verb: an evolutionary process that leads to the origin and maintenance of a certain trait! Slide 5: two types of selections: arti cial selection! Domesticated plant and animals; experimental evolution in genetics! Purposeful, has a goal: natural selection! No certain purpose or goal, a blind mechanistic process with no foresight! Slide #7: types of natural selection on quantitative traits! Average population is the ttest and favoured!
