Question

The researchers placed white and brown mouse models both in abandoned fields on the mainland (dark soil) and on sand dunes on the islands (light soil) and then measured the percentage of models that were attacked by predators. What is the take-home message of the data? Do the data support or reject the hypothesis that mouse color is adaptive?

Accepted Answer

Hello everyone and welcome to today's video. So we have that. A researcher observes that the number of green beetles on a shrub is significantly higher than the number of red battles. She concluded that the color of the Beatles is blank because the green beetles blended in with the green leaves and were not recognized by predators. So it appears that the color of the green beetles is a very positive trait because it allows them to blend in and not be consumed by these predators. So let's keep this in mind as we solve the problem. Beginning by answer choice. A vestigial. These are structures that are kept during evolution. However, they serve no function. It seems that the color of the vittles serves a very important function of keeping them safe from predators. So there are no vestigial structures and we're going to cancel this out. Then we have non adaptive traits. And this is going to be an incorrect answer choice because none of the active trades are neutral or negative traits that basically impact and organisms negatively or they don't impact their survival capabilities at all. It seems that the color helps them be safe. So we're going to cancel this out. It is not a non adaptive trade. Then we have transitional and these are traits that are in the process of transitioning between an ancestral state. It is not stated that the red color that the green color of the Beatles is a transitional trade or anything that has to do with ancestral traits. So we're going to cancel this out. And this leaves us with adaptive traits. and this is exactly what the color of the green beetles is is an adapted traits because it allows them to survive. It's a positive adaptation that increases their survivability in the shrub by allowing them not to be recognized by predators. So we're going to highlight answer choice B as a final answer to your question. I really hope this video helped you, and I'll see you on the next one.
