Evolutionary psychology

• What is survival of the fittest?

  the ones who have the genes that make them survive in an environment are more likely to reproduce and pass on the genes – the genes are naturally selected
• What is the genome lag?

  genes are far behind environment in evolving - environment is constantly changing - genes take ages to evolve
• What is the fight, flight and freeze response

  response to a threat in an environment

  fight - confront threat

  flight - run away

  freeze - stay still and don't move

  activated by sympathetic division of the ANS

  False FFF responses can be triggered by anxiety -stops body from being able to stop the false reactions
• Environmental evolutionary adaptation

  Mind and behaviours adapt to fit in with the environment - apes evolved from 4 to 2 legs as they were hunters and it made them better for their job
• Strengths ?

  women have a greater role in the workplace and are less dependent on men - love for love not just convivence to stay alive
• Weaknesses?

  Evolutions of characteristics was said to have stopped 10,000 years ago but the gene to digest milk was selected and passed on less than 10,000 years ago

  Gender bias - FFF response explains men's response to a threat but not a women's - disadvantage to women ancestors - they were protecting offspring - biased towards men's behaviour
