Chapter 9 Flashcards
individuals and species vary in form and structive, physiology and behaviour. Influenced by our genotypes
variation
idea that variation in species is heritable in its path from one generation to the next. Variation exists and it’s inherited.
Heritability
due to high numbers of individuals, successful species will compete for sources; only so many mates, only so much food
competition
due to competition, some mates will produce more offsrping than others.
natural selection
when species become adapted to their enviroment
adaptations
3 components of adaption
Domain-specificity: adaptions must solve particular problems in particular domains/circumstances
Functionality - adaptions must serve a purpose

quality - invest time/resources into child
parental investment
