Document Summary

List of provided dates, periods, and events that you will need to know. Be able to match the event to the period and the age and put them in order. African grassland expansion coincides with homo genus traits : bipedal, Some arguments for these occurrences: large brain, dentition. Selection for larger brain size because of variable environments, bipedalism helps for tools + hunting in open grassland environment. We started feeding more on meat= change in dentition. Homo erectus emigration out of africa > 1 mya: neanderthalensis ~ . 25 mya. Guide us toward predicting impacts: habitat loss, species-area relationships i. ii. iii. to california where we anticipate human. This has particular relevant population increasing from 35 to 50 million. Aquatic environments are especially in big trouble for habitat degradation. 4 top groups: freshwater mussels, crayfish, amphibians, freshwater fishes. A major component of protecting biodiversity is public land (national parks, wildlife refuges)
