=LAB 2=

In the manual: - p. 23, 1st paragraph: change 'kingdom eubacteria' to 'domain bacteria' and delete 'and the Kingdom Protista'. Protista is not considered a unique classification since around 1990. Worksheet:
 * last question: change 'kingdom eubacteria' to 'domain eubacteria'

Quiz on WEDNESDAY will cover Lab 1 and Lab 2 lecture material. Email me or set up a time to chat if you have any questions.

Lecture notes:


 * More hypothesis testing:
 * When you see an unknown organism (at least you think it's an organism), you may try to guess what kind it is. This is a hypothesis!
 * 1) Look at the organism, check out its behavior, etc. (evidence)
 * 2) Compare what you observe with what you know about various animals (refer to charts, your books, etc.).
 * 3) If you have narrowed-down the possibilities, you may have figured out what kind of organism it is. If you can't narrow it down, you go back to step 1.

- Classification of species based on ability to reproduce with another individual, and also on shared biological traits that help the organism survive (behavioral, genetic, morphology, etc.). - Genus & species nomenclature; also there are higher levels of organization, such as domain, family, etc. - Eukaryote and Prokaryote is an example of a very fundamental classification (e.g., one classification has a nucleus, one does not have a membrane-bound nucleus) - Symbiotic relationships. They can be used to classify organisms into species since these relationships are based on behavioral and biological traits (predator-prey, parasite-host, mutualist-mutualist).
