Document Summary
Covers most material off of the assignments: discussion questions from groups; group marks count as total grade during the mid term. Niche assignment fundamental: fundamental; all the space that we can live. Non-living variable; weather, water, etc: define fundamental niches of humans. What is the extreme: describe niche before and niche afterwards; do not talk about yourself. Beavers have the second largest ecological footprint; right behind humans: beavers niche has been around for a very long time; Summarise please : simple cells /complex cells/ multi-cellular, simple cells: prokaryotes, evolved complex cells: eukaryotes, by endosymbiosis. 6 mya: life accord when life had the right ingredients and the opportunity . Evolution: the change in genetic composition of a population over the successive generations, which can be caused by processes such as inbreeding, hybridization, or mutation. Genetic composition: a unit of heredity. Genes, found along stretches of dna, usually code for a protein that may have some impact on the organism.
