Introduction to the Lab &
Evolution

2. Outcomes Outcome 3: I can safely conduct an experiment
Outcomes 4: I can analyze data
Outcome 22: I can explain the process of evolution
Outcome 23: I can explain the role of DNA in evolution and biodiversity

3. Safety Equipment

4. Steps to take before performing an experiment?
Read and understand the experiment/activity!
Ask questions
You are wearing appropriate clothing
Collect all equipment
Make sure everything is in working order
Make sure your space is clean & clear and you won’t harm anyone around you

5. Genetic Equilibrium
Definition:
This does not happen when? -

6. Genetic Drift Definition: Always good?
Random change in the frequency of alleles in a population
Always good?

7. Founder Effect When does this happen? Example:
When a small sample of a population settles in a location separated from the rest of the population
Example:
What does this mean for the alleles?

8. Bottleneck Definition:
when a population declines to a very low number and then rebounds
Example:

9. Gene Flow
Definition:
Genes enter or leave a population

10. Nonrandom Mating Definition: Can lead to what?
Mates chosen based on specific characteristics
Can lead to what?

11. Genetic Mutations
Definition:
How does this correspond with evolution?

12. Natural Selection
Acts to select the individuals that are best adapted for survival and reproduction
There are three ways that Natural Selection can change populations
What are they? -

16. Sexual Selection
Occurs when certain traits are inherited because they increase the chance of attracting a mate.
What populations does this happen in?
Always good?

17. Speciation
Definition:
Two ways this can happen -

18. Types of Speciation Allopatric speciation: Example:
Sympatric speciation:

19. Homologous vs. Analogous
Definitions:
Homologous structure:
Analogous structure:

20. Divergent vs Convergent
Divergent evolution:
Example:
Convergent evolution:

21. Convergent evolution
Unrelated species evolve similar traits even though they live in different pars of the world.

22. Coevolution
Relationship between two species might be so close that the evolution of one species affects the evolution of the other species
Mutualism:

23. How quickly do species evolve?
Gradualism:
Punctuated equilibrium
