II.a. The Modern Synthesis

1.) Hereditary Variations
2.) Genes Mutate — New alleles
3.) Populational Process — allele frequencies
4.) Natural Selection can alter populations beyond the original range of variation by increasing the frequency of alleles that give rise to new phenotypes.
5.) Speciation is the origin of two or more species from a single common ancestor

II.a-1.) Mechanisms for Change: Mutation


II.a-2.) Mechanisms for Change: Natural Selection

Natural selection is the primary guiding hand for evolutionary change. This was first recognized by Charles Darwin on his tour of the Galapagos Islands during his famouse voyage aboard HMS Beagle.

II.b-1.) Prokaryotes versus Eukaryotes

Prokaryote evolution might not be describable according to the standard “tree” model (Bapteste et al.).
