Distinguish between microevolution and macroevolution.

Question

Accepted Answer

Hello everyone and welcome to today's video. Today we have that a group of mosquitoes developed resistance to DDT allowing them to survive and reproduce even after DDT exposure. This is an example of Well, before we jump into this problem, I really need you to realize that only a group of mosquitoes developed resistance to DDT, not the entire species. So only a small population of these mosquitoes were able to develop this resistance to DDT. Now let's go over our answer choices so that we may begin solving the problem. Beginning by answer choice. The hybrid. We create a hybrid when we have made in between two different species, this is not what is happening in the question. So we're going to cancel this out. Then we have speciation and speciation involves the creation of a new species. Now new trades are developed which is this DDT resistance but nowhere in the question is stated that this leads to a new species. So we're going to cancel this out as well. And then we're left with micro or macro evolution which can be classified as the creation of new trade within a species. However, there are differences between the two since not the entire species was affected and only as small group of mosquitoes were able to develop this resistance to DDT. This can be classified as micro evolution. Now, if the entire species was affected and the entire species now was able to develop this resistance to DDT then we would have micro revolution, but this is not the case. So we're going to cancel this out and highlight answer choice, A micro evolution. As a final answer to your question. I really hope this video helped you, and I hope to see you on the next one.
