Product Description
This 91-slide teaching PowerPoint presentation covers 1.A (Evolution) 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).

This product includes four sections (sub-products):

     • 1.A.1 - Natural Selection
     • 1.A.2 - Population Phenotypes
     • 1.A.3 - Genetic Drift
     • 1.A.4 - Evidence for Evolution

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.

Suggested Use:

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.A.1 - Natural Selection

a. According to Darwin’s theory of natural selection, competition for limited resources results in di#erential survival. Individuals with more favorable phenotypes are more likely to survive and produce more offspring, thus passing traits to subsequent generations.

b. Evolutionary fitness is measured by reproductive success.

c. Genetic variation and mutation play roles in natural selection. A diverse gene pool is important for the survival of a species in a changing environment.

d. Environments can be more or less stable or fluctuating, and this affects evolutionary rate and direction; di#erent genetic variations can be selected in each generation.

e. An adaptation is a genetic variation that is favored by selection and is manifested as a trait that provides an advantage to an organism in a particular environment.

f. In addition to natural selection, chance and random events can influence the evolutionary process, especially for small populations.

g. Conditions for a population or an allele to be in Hardy-Weinberg equilibrium are below. These conditions are seldom met. Mathematical approaches are used to calculate changes in allele frequency, providing evidence for the occurrence of evolution in a population.

     (1) a large population size
     (2) absence of migration
     (3) no net mutations
     (4) random mating and
     (5) absence of selection


1.A.2 - Population Phenotypes

a. Environments change and act as selective mechanism on populations.

b. Phenotypic variations are not directed by the environment but occur through random changes in the DNA and through new gene combinations.

c. Some phenotypic variations significantly increase or decrease fitness of the organism and the population.

d. Humans impact variation in other species.



1.A.3 - Genetic Drift

a. Genetic drift is a nonselective process occurring in small populations.

b. Reduction of genetic variation within a given population can increase the di#erences between populations of the same species.



1.A.4 - Evidence for Evolution

a. Scientific evidence of biological evolution uses information from geographical, geological, physical, chemical and mathematical applications.

b. Molecular, morphological and genetic information of existing and extinct organisms add to our understanding of evolution.

     - 1. Fossils can be dated by a variety of methods that provide evidence for evolution. These include
          the age of the rocks where a fossil is found, the rate of decay of isotopes including carbon-14,
          the relationships within phylogenetic trees, and the mathematical calculations that take into account
          information from chemical properties and/or geographical data.
     - 2. Morphological homologies represent features shared by common ancestry. Vestigial structures
          are remnants of functional structures, which can be compared to fossils and provide evidence
          for evolution.
     - 3. Biochemical and genetic similarities, in particular DNA nucleotide and protein sequences, provide
          evidence for evolution and ancestry.
     - 4. Mathematical models and simulations can be used to illustrate and support evolutionary concepts.
