What environmental conditions would make it helpful to have more fur as seen in Generation 2? Explain.
CFS:
accurately uses visual data to draw conclusions on population variations
describes the cause and effect relationship between environmental factors and species traits
"I think that if there are animals with more fur, the environment must be ...."

**think: what temerature is best for lots of fur

Unit 8: Natural Selection
Chapter 1: Environmental Change and Trait Distribution
Lesson 1.4: Investigating changes in trait distribution

Goal:
·  Observe why the distribution of fur traits changes over time.

Do:
Open the Natural Selection Simulation and open the mode: Fur and Temperature A.
Change the temperature of the environment to cold (Level 1) by moving the    Temperature slider.
Press RUN and observe the population for at least 50 generations.
Press ANALYZE and compare starting and ending histograms.

Tips:
·  Press the Reset button and repeat your test to see if you observe the same changes each time.

Observe and record the distribution of fur traits changes over time.

What environmental changes cause the distribution of fur traits to change over time?

What evidence do you have to support the differences in the two histograms above?
CFS:
accurately uses visual data to draw conclusions on population variations
