Goal: Show what caused there to be some extremely poisonous newts in the newt population when there were none in the population 200 generations ago.Do:- Analyze all four histograms and environment descriptions.
- Label each histogram with any Trait labels that apply.
Tips:- You can add multiple Trait labels to a single trait.
- You can use Trait labels more than once, and you do not have to use all of them.

Did mutations affect which trait was the most common at Time 3? Why or why not?
CFS:- accurately identifies the adaptive trait in the environment
- accurately identifies traits based mutations or natual selection
- accurately describes the environment in which a trait is adpative
- accurately describes how adaptive traits become more common in an environment
