ANTH 100A Lecture Notes - Lecture 53: Human Y-Chromosome Dna Haplogroup
Document Summary
Recent studied of human variation indicate that: Few sharp borders in traits between human populations. Populations could be groups in different ways using different traits. Mtdna and y-dna variation an be use to group relationships. All human groups appear to share a relatively recent common ancestor. Smaller and more closed related groups may share some typical traits. They still show much more internal variation. Most genetic variation is seen within racial groups. Variation between racial groups accounts for relatively small % of total human variation. Reflects broad nature of classic racial groups. Reflects fact that racial groups are defined using few selected traits. Last topic we looked at how anthropologists understand biological variation. This topic examines the way people understand (and create) variation or differences. Social stratifications (class and caste) reviewish. Skin colour is the most noticeable way humans vary so most systems were based on it. ~1350 bce egyptians were classifying people based on skin colour.
