Document Summary

So what is evolution: evolution is changes in allelic or genotypic frequencies from one generation to the next. Mutations: mutation: the ultimate source of all genetic variation within species and population, some being incorporated, some being eliminated. Populations and species south of the glacial maximum are more genetically diverse than those of the north. The origin of plant species: species is a lati(cid:374) (cid:449)ord (cid:373)ea(cid:374)i(cid:374)g (cid:862)ki(cid:374)d(cid:863) or (cid:862)appeara(cid:374)(cid:272)e(cid:863) (morphological species concept) What is the tempo of speciation: the gradualistic model is an extrapolation of microevolution, ancestor on the bottom, branches off and each branch continues upwards through evolution, there are intermediate species within the model, before the (cid:862)fi(cid:374)al(cid:863) e(cid:373)erges. Punctuated equilibrium model: original species at the base, goes upward with time, but will have 2 (ish) branch off from the original species branch, there will be 3 species together on the final tree.
