BIOL 1002 : Biology Notes Exam 1
Document Summary
Taxonomy- branch of biology concerned with naming and classifying the diverse forms of life on our planet. Many ways that things can be grouped ex: plants/animals (botany & zoology) - a lot of rearrangement. Taxonomic categories: organization of taxonomic groupings arranges organisms in sets, each set is then grouped with other sets into a larger set, major taxonomic categories from most inclusive (biggest) to least inclusive (smallest) Organisms that were once placed together in certain classification groups have been separated when new or better evidence in uncovered. Chromosome bonding patterns of humans and chimps are over 99% identical. The golden mole is closely related to elephants. The more biologists look, the more species are found. There are about 1. 4 million identified species and possibly 5-75 x"s more which have not been classified. Prokaryotes range in size from 0. 2-1. 0 micro meters/micron. Unicellular eukaryotes range in size from 10-100 microns. Life on the planet began about 4 million years ago.
