Document Summary
Lecture 1: introduction to evolutionary biology: important people, dobzhansky. Fruit fly geneticist: made fruit fly the model organism for genetics. Provided the first theory of natural selection and evolution: concepts. Ult)mate (cid:523)(cid:498)why questions(cid:499)(cid:524: defines the genetic & physiological processes, defines the biological & adaptive function of a responsible for a characteristic trait. M)croevolut)on (cid:523)(cid:498)evolutionary mechanisms(cid:499)(cid:524: experimental and process-based, analyses theoretical models through lab and field experiments, defines the genetic and evolutionary tools needed for evolutionary change, uses various organisms to study natural selection, speciation and adaptation at the population-level. Macroevolut)on (cid:523)(cid:498)evolutionary history(cid:499)(cid:524: non-experimental and pattern-based, compares data from several sources including morphology, genomics and biogeography, uses phylogenetics (common ancestry) to define the evolutionary relationships between organisms. Same data gathered from the several species. (cid:498)what happens in closely related species(cid:499): observational. Describes and quantifies using nature patterns (ex. Observing the organism in its environment: experimental. Requires an experiment and statistical analysis to create a system to address a hypothesis.
