1 Support for Out of Africa model

Support for Out of Africa model

mtDNA analysis from 53 humans of varied ethnic backgrounds Data suggest all had a common ancestor about 170,000 years ago Distinct branch on the tree about 52,000 years ago, separating Africans from non-Africans

2 Homo neanderthalensis

Homo neanderthalensis

Appeared in northern Europe about 230,000 years ago Cold-adapted Taxonomic affinities poorly understood

3 Europe

Europe

About 34,000 years ago, Homo neanderthalensis abruptly disappeared Tool makers Lived in huts or caves Dead buried with flowers, food and weapons Replaced by H. sapiens (Cro-Magnon man) Cro-Magnon man had a lighter body Cave art Probably had full language capabilities

25 Common features of these habitats

Common features of these habitats

Hot, dry summers and wet, mild winters All about the same latitude Fire-resistant shrubs with hard leaves Shrubs often with spines

26 Mediterranean communities

Mediterranean communities

The five communities contain more plant species than tropical Africa and Asia combined The south European-north African Mediterranean community alone has 20,000 species of angiosperms (out of a total of 250,000 world-wide)

27 Mediterranean communities

Mediterranean communities

Despite the similarity of the flora, there is little taxonomic affinity among the communities Rather, each community has species derived from endemic ancestors In southern Europe, oaks dominate In South Africa, heathers dominate In Australia, wattles dominate

28 Mediterranean communities

Mediterranean communities

Wine tastes the same because it is the same Native plants look the same but are distinct The likeness of fynbos, kwongan, mattoral, chaparral and garrigue reflects five independent responses to the force of natural selection The native flora, not wine grapes, make the case for evolution
