Question

A team led by evolutionary biologist Hopi Hoekstra set out to test the hypothesis that predators are an agent of natural selection on mouse color. They made 250 plasticine models of mice that were alike in every way except that half were painted white and half were painted brown. Suggest one advantage and one disadvantage of using model mice instead of real mice in this experiment.

Accepted Answer

Welcome back. Here's our next question. Identify the drawback of using models in evolutionary biology research. So let's go through our answer choices here. Choice A. Says the models can be created easily. Well, that's an advantage of using models much easier to create a model versus go out into the field. Choice B says they're inexpensive to manufacture again. That's also an advantage of using a model. Um So that would not be a correct answer. Choice C says they are less difficult to work with than live organisms. Well, that's correct. And is also in advance another advantage of using models. So not our answer. So we're down to choice B. D. Excuse me, They do not exhibit the same behavior and responses as live organisms. Well, this is a drawback of using models. For example, if you were studying the effect of predators and prey population, uh your model prey are not going to run away from predators. So uh the drawback of models is that you won't get that behavior and the responses you see with live organisms. So that would be choice D As a disadvantage drawback of using models and evolutionary biology research. See you in the next video
