Bis 2C, Pre-Lab #2 Bacteria and Archaea are often collectively referred to as prokaryotes because they lack a nucleus (pro=before, karyon=nucleus). But, as you can see from figure 2.1, they are not each other’s closest relatives. Because bacteria and archaea are so diverse, they can be difficult to characterize. However, when compared to eukaryotes, they have significant differences in their general biology including, reproduction, organization of genetic material, and a lack of membrane...

Evolution - The change in allele frequencies in a population over time Selection - Changes in allele frequencies due to organisms with advantageous alleles reproducing more successfully than organisms with other alleles Genetic Drift - Random changes in allele frequencies in a population Mutation - The source of all new allelic diversity Migration - Movement of alleles between populations Adaptation - A trait that evolves by selection for a particular function (because it increases fitness...
