Add labels to the figure that follows, which illustrates the three steps required for speciation to occur.

hello everyone. And in today's video we have the following problem. So new species can arise through remember this process of the arrival of new species is called speciation. So all of our answer choices contain the word speciation. So this is a good sign. But let's go over them so that we can confirm what our final answer will be. So, beginning by Allah Patrick speciation, which is our first answer choice. This ala Patrick speciation is when species develop. So speciation occurs from geographical barriers. Again, this geographical barriers promote isolation and prevent the exchange of a leos. And what this happens is that new species arise from these interbreeding stops and so new species arise from these. So this isn't correct answer choice and we will not cancel it out. Then we have answer choice. B seeing Patrick speciation. And this is when species develops. A speciation here occurs as well without a geographical barrier. So the species are in the same community or in the same groups without a geographical barrier. And they choose. New species arise through several processes. So it is also a speciation and we will not cancel it out. Then we have per patrick speciation which is when species developed in contiguous, it's kind of in between both of them. So they are in continuous yet segregated habitat. So they're not completely isolated but they do exist in segregated habitat. So a little exchange still occurs. However, if they're not in the same habitat as we see in Saint Patrick's appreciation. So this is also a type of speciation. This will also lead to new species developing and we will not cancel it out. We will not. We were not able to cancel out any of our answer choices. The correct answer choice is going to be the all of these, and that will be the final answer to our question. So I really hope this video helped you, and I hope to see you on the next one.
