Natural selection and Genetic drift

Accepted Answer

Hello everyone and welcome to today's video. So, natural selection and genetic drift are the mechanisms for evolution, which of the following statements regarding these two mechanisms is going to be incorrect. Remember that we're looking for the false statement. So let's go over each of the statements in this question so that we may solve the problem. Let's begin by answer choice eight in genetic drift, a population straight frequencies change solely by chance. Well, this is going to be a true statement because remember from previous videos that genetic drift is going to refer to the random flock to Asian of a leo frequencies in our population. And therefore we're going to be canceling this out. Then we have the in natural selection and low frequencies change by differential reproductive success. Well, this is actually going to be true as well. Individuals that have higher fitness are going to be favored and their all that they're going to be carrying are going to have a higher chance to be passed on to the next generation from reproduction. This is also a true statement. So we're going to cancel it out. Then we have the indiscriminate animal hunting is an example of genetic drift. Well, when we have indiscriminate animal hunting or over hunting, we're putting, we're drastically changing or reducing the ideal frequencies of a certain population. This is an example of a bottleneck effect and the bottleneck effect is a type of genetic drift. And therefore, this is going to be a true thing. So we're going to cancel it out and then we have a natural disaster is an example of natural selection. Well, let's think about it this way. If we have a natural disasters such as a tsunami of a or a forest, forest fire, we're going to be again drastically reducing the frequencies of a population. We're going to be affecting this population severely. But these are examples of bottleneck effects. These are not going to be examples of natural selection because as we said, the bottleneck effect is an example of genetic drift. This answer choice is going to be incorrect. Since the question is asking us for the incorrect answer choice, we're going to be selecting answer choice. C A natural disaster is an example of natural selection. As the final answer for this question, I really hope this helped and I hope to see you on the next one.
