So the question is asking us how selection occurs in the actual process of natural selection. Eso will again examine this question using, um, Darwin's finches on the Galapagos. Um, so you have, um, finches on the Galapagos that are breeding and producing offspring. Um, more often than not, the offspring of these finches tend to have the same beak size as the parent. But some will have their beak a little bit larger, and some will have the big A little bit smaller. Um, and you can assume that this is true for all finches on the islands. So then what you end up getting is this distribution of all finches on the Galapagos, where a minority have small weeks. Another minority have, um, large beaks. But most of the finches have average sized beaks. Um, and recalling the text, it was mentioned that during dry seasons on the islands, plants produce large, tough seeds. Um, and these seeds confer ah, difficulty for the finches, depending on their beak sized. Um, these large and tough seeds air easily handled by large beaks but are difficult to open for small beaks. So finches with small beaks are unable to um handle these seeds and have lo have lower fitness in dry seasons. Um, and in rainy seasons, plants produce small soft seeds. Um, and these small soft seeds are easily handled by small beaks. Um, which give them higher for this during this PC Zinn's. But the seeds are difficult to handle for large beaks. So in the rainy seasons, the, um, the large beaks have lower fitness in the scenario, um, so the way selection occurs is through generate three generations and flew multiple seasons. Say, for example, that there was a period with multiple dry seasons. So what you'd see is that, um, following one generation of the finches, there would tend to be more finches, um, with larger beak size and the next generation of finches. If these dry seasons persist would also be the same. So overall the proportion of finches on the islands which shift until most of the benches on the islands have large beak sizes. If these dry seasons persists. And this would be true, um, for protesting rainy seasons as well, um, with finches with small beaks. And that is because, um, these environmental conditions the dry seasons, where the rainy seasons are selecting for the treat that offer the highest fitness in terms of dry seasons, the trade that offers the highest fitness is having large beaks in in rainy seasons. The trade that offers the highest fitness is having small kicks, and it is through these persistent conditions and, um, the advantage increased fitness that selection occurs.
