eveloution and genetics Flashcards
what is evolution
the process of change over generations in which the characteristics that er inherit are adapted to fit a certain function
what other ao1 evidence can you give to back up evolution
EEA
what is EEA
aggression has evolved to provide an adaptive function
give an example of EEA
that males have evolved to be physically bigger and stronger provides resources for their off spring
in and 8 marker what would be the final two ao1 points based on
epigentics
what would this epigenetics point be split into
males and female
give the males point
have evolved to be more agressive to protect their mate and offspring. this also provides them social status to compete against other males and impress potential mates thus continuing their genetic line
give the epiginetics female point
females have evolved to be less agressive and more nurturing to spend long peroids of time looking after children
who argues aginst the idea of womans lack of agression
BUSSsuggests women are more socially agressive so the they will look less attractive to potential mates and those degrading will look more attractive
what is a weakness of the theory of evolution
it is post hoc
what does post hoc mean
pst hoc assumption rather than proven fact. making judgements on past behaviour looking back and applying this judgement to pressent situations.t/f raises the question of the validity of the theory of aggression
what is the suuporting reasearch for evolution
mazure differance in inter-male fighting of rats around puberty, when their is an increase in aggressiont/f this leads supports the idea that agression is linked to genes and instincts in males.
how can the differance between males and femals support evolution
differance in bran structure
what is the difference in brain structure due to
high levels of tesosterone before and after birth
what is this liked to
aggression in malesand nurture in woment/f brain difference is linked to their adaptive function
