Description
Sep 21/12: Human Biological Diversity September-21-12 7:51 AM Sep 21, 2012 Why the Concept of Biological Races is Rejected - There is no natural way toclassify humansinto biologicallymeaningful categories - There are no "pure" races because all populations have beenin contact (interbreeding)with othersduringtheirhistory and they are constantly changing. - There is more geneticvariation withingroups thanbetween groups.(we are more similaron the insidethanon the outside) - Phenotypesimilaritiesmake up a very small fraction ofsimilaritiesin the human race - genotype similaritiesare far far more! - The Human Genome project showed the above - There is very littlegeneticdiversity in thehuman species asthey haven'tbeen around that long - All humanshave a common ancestorof Chimpanzees - Chimpanzeeshave20x more diversity than humans - Races are no more than cultural constructionsbased on arbitrary characteristics - Cultural Construct:somethingthat people have madeup. In different culturesthey have different conceptionsof groupings(different culturesgroup people usingdifferent physical features) - Biological characteristicsare not linkedwith abilitiesor behaviours.
