Mrs. Yarborough explains the naming Taxonomy of science.

Please turn to page 46 to record notes about Taxonomy. First let's Define taxonomy. Taxonomy is the system in which organisms are classified according to similarities and differences. I should be able to write their two similarities and their differences. We do have levels classification using the pyramid. I'm going to write on the pyramid first before I tape it or glue it in my Journal. The reason is shaped like this is because it represents the number of organisms in that level so the largest level is call the domain and that has many, many, many organisms in that and there's three - there's only three and then there is Eukarya which is all of the eukaryotes classified in a domain. You classify and in phylum and then class, genus and then species. Go ahead and get some tape or glue we're going to glue that right about here in your Journal. Now I'm going to talk about what happens as we move from domain to species that I'm going to write that on this side. Draw an arrow moving down for species as we move from domain to species we're going to get more specific in the organisms and their characteristics. For instance if I say a plant is in the Kingdom plantae there's millions up to species of plants. But if I say there's talk about a plan and a certain family that definitely narrows down or becomes more specific on which type of plant we're talking about. It happens as we move from domain to species is that the organisms get more closely related. Now to help you with the order of the levels of classification there's a mnemonic that we're going to write down. I'm going to write it down on this side of the pyramid the mnemonic is Dear King Philip Came Over For Good Spaghetti. so if you can memorize Dear King Phillip Came Over For Good Spaghetti you have memory order of the levels of classification Domain Kingdom Phylum Class Order Family Genus and Species. Their scientific names we use a system called binomial nomenclature - going to write that right here. Organisms are named using binomial nomenclature and that just means that all organisms start giving a two-part name. For instance, our modern humans use humans walking around our scientific name is capital h o m o in a little Sapien homo sapiens if since I'm handwriting this this is supposed to be in italics but since I'm handwriting I'm going to underline Homo sapiens the first part of our scientific name is the genus it must be capitalized in a second part of our scientific name is the species and that is lowercase and as we are the only species left all the other species within our genus are extinct so that's page 46 in your Journal.
