PSYCH 3F03 Lecture Notes - Lecture 2: Phylogenetic Tree, Special Creation, Ontogeny
Document Summary
Learn 2 major principles of lamark"s theory of evolution (and understand why they"re flawed) Learn and describe 3 major criteria required for ns to occur. Learn the difference between ultimate vs proximate mechanisms, and the 4 questions" of behaviour. With our modern biological findings, we know that these 3 points are inaccurate. Inheritance was understood back then, but its mechanisms were not. Variation provides the raw material" for evolution heritability: the process of parents passing on their heritable genetic material to their offspring. But: only some variations are inherited characteristics influenced by the environment are not. We know that genes are the mode of all inheritance: for phenotypic variation to involve, has to be responsible by the genetic material. To answer these questions, came up with the theory of ss: a mode of ns in relation to sex (i. e. reproductive success) Alfred wallace: independently and simultaneously conceived a theory of evolution by ns.
