Karyon - Study guides, Class notes & Summaries

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...

Coevolution Event The process by which two or more species evolve in tandem by exerting selection pressures on each other Speciation Event A lineage-splitting event that produces two or more separate species. Phylogenetic Event The evolutionary development and history of a species or higher taxonomic grouping of organisms. Also called phylogenesis. The evolutionary development of an organ or other part of an organism Homology Event Shared trait among species Mutat...
