This 39-slide teaching PowerPoint presentation covers 1.B (Phylogeny) in the AP Biology (2015) curriculum. Each slide includes the 'Essential Knowledge' being covered as well as key terms that students should make note of (editable).
Section 1.B includes two sections:
• 1.B.1 - Shared Traits
• 1.B.2 - Phylogenetic Trees
The presentations themselves contains minimal information as they are intended to be used with teacher guidance. There are 'Video' slides throughout which link to relevant and informative YouTube content. The slides are formatted to be visually pleasing and to also print well for handouts or revision. Please see the preview file (first 8 slides) for an idea of the aesthetic and level of detail in the presentation. The relevant 'Essential Knowledge' can be found below.
I have had success using these presentations to review topics after students have been exposed to the material at home. I typically have the class read relevant material (book, site, etc.) and then watch the videos the day before introducing a topic. During the class period, I use the slides to structure the discussion around the AP Bio Essential Knowledge objectives. The remaining class time is spent reinforcing the knowledge or working on activities geared toward the 'Learning Objectives'.
I have included PDF copies of the PowerPoints for handout purposes.
**These presentations are based on the AP Biology Course Guide and does not follow any textbook
As always, please let me know if you have any suggestions for improvements. These are always a work in progress!

The Essential Knowledge covered includes:
1.B.1 - Shared Traits
Organisms share many conserved core processes and features that evolved and are widely distributed among organisms today.
a. Structural and functional evidence supports the relatedness of all domains.
- 1. DNA and RNA are carriers of genetic information through transcription, translation and replication.
- 2. Major features of the genetic code are shared by all modern living systems.
- 3. Metabolic pathways are conserved across all currently recognized domains.
- 4. These complex reaction sets could have occurred in solution (organic soup model) or as reactions on solid
- 5. The RNA World hypothesis proposes that RNA could have been the earliest genetic material.
b. Structural evidence supports the relatedness of all eukaryotes.
- 1. Cytoskeleton (a network of structural proteins that facilitate cell movement, morphological integrity
and organelle transport)
- 2. Membrane-bound organelles (mitochondria and/or chloroplasts)
- 3. Linear chromosomes
- 4. Endomembrane systems, including the nuclear envelope
1.B.2 - Phylogenetic Trees
Phylogenetic trees and cladograms are graphical representations (models) of evolutionary history that can be tested.
a. Phylogenetic trees and cladograms can represent traits that are either derived or lost due to evolution.
- 1. Number of heart chambers in animals
- 2. Opposable thumbs
- 3. Absence of legs in some sea mammals
b. Phylogenetic trees and cladograms illustrate speciation that has occurred, in that relatedness of any two groups on the tree is shown by how recently two groups had a common ancestor.
c. Phylogenetic trees and cladograms can be constructed from morphological similarities of living or fossil species, and from DNA and protein sequence similarities, by employing computer programs that have sophisticated ways of measuring and representing relatedness among organisms.
d. Phylogenetic trees and cladograms are dynamic (i.e., phylogenetic trees and cladograms are constantly being revised), based on the biological data used, new mathematical and computational ideas, and current and emerging knowledge.
