Explain why you selected the answer you did in question 3.

At this point type in the chat letting me know you are done through question 4. We will read the comic below as a class. Click the link to follow along. In the mean time while you wait check out this video: https://youtu.be/9cbZmOvRySk

This is kind of a true story! In Kauai, a scientist who studied there found that suddenly one summer the crickets were far quieter than in the past. A mutation had occured in the DNA of some crickets causing them to be silent. Mutations that are beneficial will be passed on to future generations and increase in existence, those not beneficial will not be passed on in such great amounts.

Most crickets in Kauai are silent, why do you think this silent mutation is beneficial?

Explain your answer to question 8. Why is the trait you selected an adaptation for mice? Note: Adaptations are any inherited structure, behavior, or internal process that enables an organism to respond to environmental factors and survive and reproduce.

In Kauai, some male crickets can chirp, others can't. Make a claim to answer the question: Which type of cricket is more successful at surviving and reproducing?

Singing male crickets are more successful at surviving and reproducing. 

Silent male crickets are more successful at surviving and reproducing.

Refer back to the claim you selected in question 3. Based on the evidence in the comic, do you still stick with your initial claim?

Yes

No

After reading the comic, make a claim to answer the question: Which type of cricket is more successful at surviving and reproducing? (this may be the same as you chose in question 3 or different- either way select an option here)

The comic is supposed to model the idea of natural selection, the idea that individuals with traits favorable for the environment will survive and reproduce and pass their traits to the next generation. Natural selection leads to adaptations, that is, a population dominated by organisms that are anatomically, behaviorally, and physiologically well suited to survive and reproduce in a specific environment. Based on this information, in the model below, what trait would be an adaptation?

Tan fur

Black fur

Natural selection is often explained as "survival of the fittest" - based on your answers above....which of the following do you think is the best definition for fitness in this context?

The individual that is the strongest, fastest and toughest

Based on your answers to questions 11-13, is it possible for an organism to be fit in some environments and not others?

Yes

No
