BIO 321 Lecture Notes - Lecture 1: Peppered Moth, Lepidopterology, Phenotype
Document Summary
Industrial melanism in biston betularia was his major focus- studied many butterfly and moth species. Worked with ra fisher on many evolutionary genetic concepts. With fisher helped to esta(cid:456)lish the (cid:510)ea(cid:511)i(cid:511)(cid:480) o(cid:479) (cid:2522)(cid:480)e(cid:511)eti(cid:457) poly(cid:510)orphis(cid:510)(cid:2523) Proposed that polymorphisms in nature were involved with very strong selection on alleles in particular circumstances. Proposed that human blood group polymorphism may be involved in resistance to disease. Abo and rh factor are two of 33 known human blood group polymorphisms. In the other 31, variants are rare but may cause transfusion complications. Definition of fitness: the survival + reproductive success of an individual (can be defined over >1 generation and often use fitness proxies- traits that are positively correlated with fitness) Back in the day: how organisms live in nature (this has become physiological and behavioral ecology) These days- the distribution of species and communities across space and time in the environment. Ecologically important traits = traits important for fitness.
