3 questions

Scientists measured the spot size of all the guppies (small fish) that lived in a river 40 years ago. They measured the spot size of the guppy population again last year. 

Question 1

When was there more variation (number of traits) in the spot size of guppies in the river?

These bar graphs do not show the amount of variation in the population.

There was more variation 40 years ago.

There was more variation last year.

There was the same amount of variation in spot size 40 years ago and last year.

Question 2

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.

Question 3

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
