We have evidence about the population of rough skinned newts that we want to analyze. We have organized this data into two histograms, one showing the population 50 generations ago and one showing the population today.

How has the new population changed? What in the environment caused this change?

Vocabulary:
Adaptive trait: a trait that makes it more likely that an individual will survive in a specific environment
Non-adaptive trait: a trait that makes it less likely that an individual will survive in a specific environment

How does the above photo display adaptation? (look carefully, there are two moths in each picture!)

CFS:
accurately describes the relationship between environmental changes and population variations
describes the cause and effect relationship between environmental factors and illuminated species traits
"I think the image on the left above shows adaptation because ... "
(think: How do the traits allow the species to survive?)

In a brown environment, shown on the right, which trait became more common over time? Why do you think this will happen?
CFS:
accurately describes the relationship between environmental changes and population variations

Environment A:
Goal: Gather evidence to support or refute the claim: Yellow color is always an adaptive trait in a yellow environment.

Do:
• Open the Natural Selection Simulation and open the mode: Camouflage.
• Under Biotic Factors: Carnithons, make sure Include Carnithons is selected.
• Under Abiotic Factors, change the Surface-Color slider to Yellow Level 7.
• Press RUN and observe ostrilopes with different color traits for 50 generations. You can also refer to the Traits Histogram Window while the Sim is running.
• After 50 generations, press ANALYZE and compare the color traits in the starting ostrilope population to the population after 50 generations.

Tip:
·   Do not change the initial ostrilope distribution of traits.
·   Carnithons which hunt ostrilopse are in the environment

Results: 

0

Which ostrilopes were more likely to survive and became more common in the population?

0

In the simulation, was yellow color an adaptive trait in a yellow environment? Explain why.

CFS:
State your claim
Provide accurate evidence identifying how environment impacts a species population.
Includes accurate evidence to support claim.
"In the first generation I see that (describe the traits variation). In the last generation I see that (describe the traits variation). I think the traits changed to because ...

(think: what changed in the environment to cause the traits to change?)

Exit Ticket:

Why do you think yellow is not adaptive in the yellow environment shown in the graph?

CFS:
accurately describes the relationship between environmental changes and population variations
describes the cause and effect relationship between environmental factors and species traits
(If yellow is an adpative trait I think that in generation 50 it will .... (identify the expected change over time)
