This 59-slide teaching PowerPoint presentation covers 1.C (Speciation) 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).
The presentation was made to correspond to the objectives outlined in the AP Biology guide and so is ideal for moving students through the course.
Section 1.C includes three sections:
1.C.1 - Speciation
1.C.2 - Isolation
1.C.3 - Modern Evolution
The presentation itself contains minimal information as it is 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 12 slides) for an idea of the aesthetic and level of detail in the presentation.
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.C.1 - Speciation
a. Speciation rates can vary, especially when adaptive radiation occurs when new habitats become available.
b. Species extinction rates are rapid at times of ecological stress.
1.C.2 - Isolation:
a. Speciation results in diversity of life forms. Species can be physically separated by a geographic barrier such as an ocean or a mountain range, or various pre-and post-zygotic mechanisms can maintain reproductive isolation and prevent gene flow.
b. New species arise from reproductive isolation over time, which can involve scales of hundreds of thousands or even millions of years, or speciation can occur rapidly through mechanisms such as polyploidy in plants.
1.C.3 - Modern Evolution:
a. Scientific evidence supports the idea that evolution has occurred in all species.
b. Scientific evidence supports the idea that evolution continues to occur.
