Document Summary
Chapter 1: hallmarks of comparative cognition, 1. Experimental procedures: research in cc involves some experimental manipulation, behaviour observed in the wild is moved to lab, also performed in natural habitat despite extraneous variables, 3. Influence: theory of evolution by natural selection: tenets of the theory of evolution by natural selection, 1. Variation: individuals within species display variations in physiological and behavioural traits: 2. Heritability: offspring inherit traits from parents: 3. If physiological traits are shaped by evolutionary pressures, so are cognitive traits. Side effects of adaptations (belly button is byproduct of adaptive umbilical cord: random effects (noise, chance mutations that do not provide any survival and reproductive, speciation advantage. Species: group of animals capable of interbreeding and producing fertile offspring: more than one species can evolve from one common ancestor. Subpopulations of a single species may display a trait that becomes adaptive when environments change.
