Lana Crosbie A2 EVOLUTIONARY APPROACH SLIDE 2 Key concepts of the Evolutionary Approach. Natural selection- At anytime, the environment exerts selective pressure on individuals..it becomes survival of the fittest...the weak do not survive. Fitness- Extent to which a individuals characteristics allow them to adapt to their environment.

Lana Crosbie A2 EVOLUTIONARY APPROACH SLIDE 3 Key concepts of the Evolutionary Approach cont... Survival is aided by reproduction because this ensures the continuation of genes responsible for fitness. It is the characteristic rather than the individual that is selected by nature. Natural selection occurs when (a) A characteristic appears (b) The characteristic is genetically transmitted (c) The gene is adaptive.

Lana Crosbie A2 EVOLUTIONARY APPROACH SLIDE 4 Key concepts of the Evolutionary Approach cont... Sexual Selection The selection of characteristics that are concerned only with reproductive success. Females are the selectors whilst males compete for her attention. This is because males produce thousands of sperm and invest little in each ‘reproduction’, whereas females invest a great deal as they produce fewer eggs. Therefore females select their mates strategically- Basically she only wants the best and nothing less!!

Lana Crosbie A2 EVOLUTIONARY APPROACH SLIDE 5 Key concepts of the Evolutionary Approach cont... Kin Selection. Passing on ones genes directly (offspring) and indirectly (helping relatives)..the total number of genes passed on through the above equates to inclusive fitness.

Lana Crosbie A2 EVOLUTIONARY APPROACH SLIDE 6 Key concepts of the Evolutionary Approach cont... The Modular Mind. This is explained as ultimate rather than proximate levels of causation. Proximate: Concerned with the here and now. Ultimate: Concerned with (EEA) environment of evolutionary adaptiveness. (How we used to behave, how the behaviour has adapted to now)

Lana Crosbie A2 EVOLUTIONARY APPROACH SLIDE 7 Evaluation of Evolutionary Approach. Not reductionist- It fully considers the meaning of our behaviour. Increases our knowledge of Nature Nurture with discussions on Genes and how they are vulnerable to environmental changes. (X) Maybe argued as reductionist- Behaviour reduced to genetic factors. (X) Ignores cultural influences on our behaviour.

Lana Crosbie A2 EVOLUTIONARY APPROACH SLIDE 8 Methodology used by evolutionary approach. 1.Naturalistic observations 2.Experiments: mainly with non-human animals. 3.Cross cultural studies. 4.Surveys/Interviews Look back at PYA3 notes for more details on these research methods as well as the strengths and limitations.
