S4.3.4 For the adult
Classification
Why does every species get a two part name, such as Homo sapiens?
What this chapter teaches
Living things are sorted into seven levels from kingdom to species, each inside a bigger one. Every species has a two part name: the genus with a capital letter and the species name in lower case, in italics in print. DNA evidence led to three domains and moved some species to new groups.
Three questions to ask
There is no one right wording. Listen for the idea.
- Why is a two part name more useful than a common name?
- What does it tell you when two animals share a genus?
- Why can looks mislead when we sort living things?
After the chapter, the learner can
- Explain the two part naming system, such as Homo sapiens
- Explain how DNA evidence changed the way we group living things
What they copy into their notebook
Seven levels: kingdom, phylum, class, order, family, genus, species. A species has a two part name, such as Homo sapiens. DNA led to three domains: Bacteria, Archaea and Eukarya.
