Document Summary
Ecosystems: this section will focus mainly at the population level as this is the primary unit of evolution, populations basic unit that evolves. We are born with the genes we inherit from our parents and we die with them. What are the fitness consequences of a flower flowering in may vs. in. A variety of approaches are used to address questions; the best studies use more than one source of evidence: Theoretical develop models verbal, graphical, mathematical. Comparative obtain same data from many species. Experimental manipulate a system to address a specific hypothesis; requires an experimental design and statistical analysis. Important assumptions about evolution verified by scientific study. Organisms on earth have changed through time. The changes are gradual not instantaneous: no species creation. Lineages split or branch by speciation resulting in the generation of biodiversity. Most evolutionary change results from natural selection the only process responsible for the evolution of biodiversity and adaptation.
