Document Summary

Classic approach is based on latin binomial and hierarchy. Modern terms have largely replaced hierarchy with more nuanced. Phylogeny: show common ancestors, time since branching, there isn"t just one way to make a phylogeny, can be rearranged without changing info, analogy convergent evolution same but not found in a common ancestor. Mess up phylogenies: monophyletic groups trace back to common ancestor then monophyletic) trace forward to all descendants (same set . Most life we are familiar with and can see with the naked eye are eukaryotes (animals, plants, fungi, algae) Eukaryotes are opposite of prokaryotes: they have no cell wall or cell wall not composed of, they have internal organelles such as golgi apparatus, peptidoglycans mitochondria (energy processors), and sometimes chloroplasts (photosynthesis) Dna and ribosomes are already attached to membrane, keep folding until they"re surrounded (nucleus / golgi apparatus) Extend cytoskeleton to flagellum and develop motion.

1) Parents from two different species mate and produce a fertileoffspring with a polyploid chromosome number. This is called

	allopolyploidy
	allopatric speciation
	triploidy
	mutation selection
	autopolyploidy

2)A monophyletic group would be best described as:

	a grouping of most, but not all, species descended from a commonancestor
	a grouping of all species descended from a common ancestor,including that ancestor
	a grouping of all species descended from a common ancestor,excluding that ancestor
	a grouping of all species that share a similar set of traits,regardless of whether the traits are homologous or analogous

3) Vicariance refers to:

	a pattern of speciation whereby new species evolve reproductiveisolation in sympatry
	a kind of speciation where a small group of colonists founds apopulation on an island habitat
	a pattern of speciation in which a population is subdivided by ageographical barrier
	a technique for constructing phylogenetic trees based onsynapomorphies

Using your knowledge of the 6 themes we have examined thus far (1. Evolution/Descent with modification, 2. Speciation, 3. Evolution of Populations, 4. Phylogenies, 5. Prokaryotes and Protist Diversity, 6. Plant and Animal Diversity), explain how evolution and diversity are connected. Provide at least three examples or evidence for your answer.
