CHAPTER OVERVIEW:

Chapter 22 – Phylogeny. This chapter explores the evolutionary history of relationships among organisms or their genes.

- The chapter begins with a description and overview of phylogeny (section 22.1). This section goes on to discuss how to read a phylogenetic tree and the relationship between phylogeny and systematics (the study and classification of biodiversity). Additional important information pertaining to fundamental concepts and connections are covered here. Read this section carefully.
- Section 22.2 discusses in great detail the mechanics of constructing phylogenetic trees. Of importance is that you understand the principle of parsimony and that phylogenetic trees are constructed based on information obtained from many sources including morphology, development, paleontology, and molecular data. Skim this section.
- Read section 22.3 carefully. Phylogenetic trees are quite useful! Perhaps the most difficult concept in this section is the molecular clock. Take some time with this part and read it carefully.
- Finally, section 22.4 discuses the relationship between phylogeny and classification. Most of you are familiar with the binomial system of nomenclature proposed by Carl Linnaeus in the 1700's. This system of naming organisms has been most useful in standardizing the names of organisms and thus ensuring that people around the world knew unequivocally which species they were talking about. Read this short section carefully. Phylogenetic relationships help organize organisms into a coherent classification system. Know the rules that govern the use of scientific names.

SUPPLEMENTAL MATERIAL: Please note that reading/viewing these materials are completely optional,  although you may find some of them interesting and/or helpful.

Phylogenetics

- Paul Anderson (Bozeman Science) is one of my favorite video teachers! His presentations are clear and concise. So, if you find you want a quick overview, I'd like to direct you to this link:

- This next link goes to a lecture provided by an unidentified professor at Yale University on this topic.

- Another good resource is available through Khan Academy. The link below will take you to a lecture on Taxonomy.

- Finally, my favorite of the online 'lecturers' in Hank of Crash Course Biology. Yeah, these are developed for AP Biology courses but none-the-less they're excellent resources for all levels!  :-)
