Discuss the various characteristics used in taxonomy and ways of classifying organisms (i.e. phenetic, phylogenetic, polyphasic classification)
Homework Answers
Various characteristics used in taxonomy are morphology, Gram reaction, nutritional classification, cell wall, lipid, cell inclusions and storage products, pigments, carbon source utilization, nitrogen source utilization, sulfur source utilization, fermentation products, gaseous needs, temperature range, pH.
Phenetic classification based on the overall similarity of the organisms being classified.
Phylogenetic classification based on the evolutionary ancestry, classifying organisms on the basis of descent from a common ancestor.
Polyphasic classification takes into account all available phenotypic and genotypic data and integrates them in a consensus type of classification, framed in a general phylogeny derived from 16S rRNA sequence analysis.

7. Classifying extinct species is difficult, and usually must integrate data from fossil measurements, inferences on ecology (e.g. classifying carnivore, herbivore using teeth, etc.), and how these are likely to change or not over deep timescales. Which of the following species concepts is likely most usable and operational for extinct taxa, like the dinosaurs in the above tree? Phenetic species concept Evolutionary species concept Biological species concept Fossil species concept None of the above 8. Theropoda (theropods) contains many of...
