Document Summary

Midterm exam is 75 minutes, 40 mc balances of material i. e. equal number of questions. Midterm includes material up to and including oct. 21st (mollusca i i) Final is 80mc, 20 from midterm 1 material and 60mc of post-midterm material. Lecture 2 september 16, 2010: classification and phylogeny (ch4, 72-88) aristotle had an interest in classifying and was the first person to start it. Linnaeus really developed the system to our current model (1700"s: based on morphology what the animal"s body shape looks like, hierarchical taxonomic framework: at the top an all encompassing group i. e. kingdoms, Phylum, class, order, family, genus and species aka 7 mandatory ranks : for larger animal groups you have way more ranks; upto 30 ranks, binomial nomenclature ex. Anguilla japonica (capital first letter for genus and species is the second work aka species epithet. Phylogeny: phylon means race and genesis means descent. Basically the history of development of species or other group.

One of the interesting things about using the Linnaean taxonomic system for classification of organisms is how little it has changed over the years. It has expanded from 2 kingdoms to 6 and it has added the higher level of domain but very few organisms have had to be moved from one classification to another. That is because Linnaeus based his classification on physiology. Today most taxonomists classify organisms based on molecular biology. In other words, they use DNA to decide which group and organism should be put into. Since the physiology of an organism depends on its DNA, almost no organisms have been moved.
Can anyone find an example of an organism that was reclassified based on its DNA?

1. James Hutton was the first to propose that geological change occurred gradually by the accumulation of small changes from processes that are occurring today, but who was the first to popularize this idea with additional geological evidence and to inspire Darwin to consider that the earth is millions of years old instead of only thousands of years old?

Charles Lyell

Charles Darwin

Jean-Baptiste Lamarck
