7.2 - Population Evolution (Microevolution)

Preview: 

As you watch....

1) List the FIVE FINGERS OF EVOLUTION. (or draw a hand with each!) 

2) Describe how each has an impact on population evolution

Lesson: 

Video Lesson #1: Hardy Weinberg

Text Pages: p. 264-275

Vocab: population, gene pool, microevolution, Hardy-Weinberg Principle, genetic drift, gene flow, founder effect, bottleneck effect, relative fitness, stabilizing selection, directional selection, disruptive selection, sexual dimorphism, sexual selection, balancing selection, frequency dependent selection

7.2 Assignments

Lactase Persistence Assignment: 

Over the next 14 days, survey friends and family about their lactose tolerance. Simply tally how many people you talk to are lactase persistent and how many are not. 

1) Please don't collect names!

2) Please be don't force the survey onto complete strangers! 

3) Please keep record (use phone notes app? or similar notes device)

- Use the document introduction to understand what Hardy-Weinberg is and how it can be used to gauge the allele frequencies within a population.

1) Record the TWO equations in your unit guide (see page in unit guide), and what each variable stands for. 

2) AND complete the first THREE practice problems.

3) Please reach out if you have questions! Practice problem #1,#2, and #3 due 3/13.

Sexual Selection Terms: Use the reading below or ch. 14 to define the terms listed (see pdf list) -  Assigned 3/12, Due 3/13 (Friday)

Day Starter from 3/27- Record in the lower square of 7.2:

- As you watch, record the four scientific fields presented in the video. Describe the evidence that supports the story of Cetacean evolution. 

Learning Targets: 

1) I can predict how allele frequency will change due to the natural mechanisms of population evolution.
