Classification & Dichotomous Keys http://www.kaycook.com/6_butterfly_html_26d9b7e5.jpg

How do you differentiate between organisms? Left: http://www.csc.villanova.edu/~ysp/Teacher/Webpages/mstp_payne/Web_project/images/peppered_moth/2moths.GIF Right: http://upload.wikimedia.org/wikipedia/commons/9/9c/Luna_Moth_by_Joey.jpg

Dichotomous keys: 2 choices, 1 correct answer Used to describe organisms Simple means of visual classification Given 2 options (with wings, without wings)  choose the correct option, proceed as directed Ex. “1a. Insect has 1 pair of wings  proceed to number 3. 1b. Insect has 2 pairs of wings  proceed to number 2.” Narrows down possible organisms/groups one trait at a time Not appropriate for individual species identification OR classifying very small organisms (bacteria, viruses, etc.)

Are they the same species? Left: Bengal tiger - http://1.bp.blogspot.com/_W90V87w3sr8/TMbyfnBa7fI/AAAAAAAAAEE/c2Qk7tsdrw0/s1600/bengal+2.jpg Right: Siberian tiger - http://us.123rf.com/400wm/400/400/enjoylife25/enjoylife250806/enjoylife25080600035/3122634-siberian-tiger--tiger-panthera-tigris-altaica-in-water.jpg

Are these the same organism? Left: E. coli - http://www.emc.maricopa.edu/faculty/farabee/biobk/96444c.jpg Right: E. coli - http://upload.wikimedia.org/wikipedia/commons/thumb/3/32/EscherichiaColi_NIAID.jpg/210px-EscherichiaColi_NIAID.jpg

Dichotomous keys ARE good for… Domain Kingdom Phylum Class Order Family Genus Species identifying down to the order or family sometimes to the genus  depends on the org. What are the levels of biological organization?

Practice: Using a simple key 1a. Has wings with feathers. Proceed to 3. 1b. Has leathery, scaly wings. Proceed to 2. 2a. Has a long, whip-like tail. Order Drachoptera 2b. Has a thick, bulky tail. Proceed to 4. 3a. Has a large, curved beak. Order Phenotera. 3b. Has a small, straight beak. Proceed to 5.
