The Adaptation Assessment Probe

12:09 PM  Admin  

I'm taking a MOOC on evolution that's designed for educators [Evolution: A Course for Educators]. One of the things that was covered in the first lecture was a test on "adpatation" taken from a book called "Uncovering Student Ideas in Science, Volume 4: 25 New Formative Assessment Probes. The book is published by the National Science Teachers Association (NSTA).

Let's take the test ...

Adaptation

Three friends were arguing about what would happen if a population of rabbits from a warm, southern climate were moved to a cold, northern climate.1 This is what they said:

Bernie: "I think all of the rabbits will try to adapt to the change."

Leo: "I think most of the rabbits will try to adapt to the change."

Phoebe: "I think few or none of the rabbits will try to adapt to the change."

Which person do you most agree with and why? Explain your ideas about adaptation.
I agree with Bernie. I think all the rabbits will try to adapt to the colder weather by finding warmer, more cozy, burrows and by cutting down on their activity during the cold nights. I think they will adapt by eating more. If hair growth is related to temperature, as it is in some mammals, then the rabbits will adapt by growing thicker coats.

Let's see how I did.

Oops! That's not the "right" answer. The correct answer is what Phoebe said. Here's what they say on the website ...
The best answer is Phoebe's: "I think few or none of the rabbits will try to adapt to the change." The key word here is try. Biological adaptation involves genetic variation that allows some individuals to survive a particular change, such as a change in the environment, better than others.
I didn't read the question carefully. I didn't notice that what they were asking about was not just "adaptation" but "adaptation by natural selection." Silly me.

We turned our clocks back one hour last weekend and I'm still adapting adjusting to the change.

If this is the kind of nonsense that the National Science Teachers Association thinks is important then it's no wonder that evolution education is in trouble.

1. Not a good test for Australian students! :-)
