BIO318Y5 Lecture Notes - Lecture 5: Parasitic Disease, Parasitoid, Electronic Assessment
Document Summary
Last lecture: fitness of both males and females are on different levels. Behavioural and other adaptations in different populations can lead to population divergence even in sympatric populations. Given the social biology of cuckoos, however, sympatric speciation is unlikely. Don"t memorize every term in the textbooks except the ones we use a lot in class. Two definitions: adaptation: a trait that increases the fitness of it"s bearer and that evolved for that specific role (versus effect, adaptive phenotype: occasionally extends beyond the organism concept of the extended phenotype. Spider making webs as an extended arm to catch and to run away. Fox poles whiteness is an adaption to running; poles did not evolve to deal with snow; example of fitness enhancing effect. Parasites manipulating hosts: hypothesis testing and the culture of science, self correcting and self critical, sexy science , parasite manipulating hosts and using as their own phenotype, cadidid.
