Document Summary

Microevolution: small changes in allele frequencies acting on the gene pool. Macroevolution: appearance of new species due to many generational changes in allele frequencies. Divergent evolution: single ancestral species gives rise to two or more descendent species. Convergent evolution: two unrelated organisms develop similarities due to similar environments. Classification: ordering of organisms into categories to show evolutionary relationships. Chordata: phylum of animal kingdom that includes vertebrates. Vertebrates: animals with segmented, bony spinal columns; have a developed brain and paired sensory structures; includes fish, amphibians, reptiles and mammals. Taxonomy: field that specializes in establishing the rules of classification. Linnaiean classification: organisms classified according to their physical similarities. Homologies: similarities between organisms based on descent from a common ancestor. Analogies: similarities between organisms based on common function with no evolutionary descent. Homoplasy: separate evolutionary development of similar characteristics in different groups of organisms.
