BI111 Chapter Notes -Evolutionary Taxonomy, Mosaic Evolution, Carl Linnaeus
Document Summary
18. 1 the significance of similarities and differences: parallel/convergent evolution: tendency among organisms living under the same conditions to develop similar body forms, convergent: phylogenetially more distantly related organisms, parallel: closely related ones. 18. 2 systemic biology: an overview: science of systematics has 2 major goals, reconstruct the phylogeny/evolutionary history of an organism, taxonomy a. Identification/naming of species and their placement in classification: classification is an arrangement of organisms into hierarchical groups that reflect their relatedness, closed genetic system means a species not hybridizing with others. 18. 6a traditional evolutionary systematics classifies organisms according to their. Evolutionary history using phenotypic similarities and differences: traditional evolutionary systematics: groups together species that share ancestral and derived characters, includes evolutionary branching and morphological divergence, recognizes 4 classes: amphibian, mammalia, reptilian, and aves (birds) Given equal ranking because each represents distinct body plan and way of life.
