Secondly, interbreeding between the islands between the populations is gonna be difficult because their islands so there's gonna be low gene flow, which means the populations on the giant land like this one, for instance, the chances of it breeding with any of these islands. Why is an ancestral species more likely to give. Remember, each one of these islands toe have different finches on them because they after from food or different water. For the lineage of spiny leg Tetragnatha, the phylogenetic analysis also shows progression down the island chain from the oldest (Kauai) to the youngest (Hawaii). Adaptive radiations on archipelagos (island chains) represent some of the best-understood speciation events. When it lands on these islands, there is pressure. Are there differences to like different substrates different, um, water supply things of that nature still just put different resource is so there's different resource is so the ancestral population. And then those food sources, our big driving cause for evolution. ![]() So what's so great about, um, what ISS so beneficial by islands? When it comes to things like a doctor? Radiation evolution is that each of these islands has different food sources on it. Some were wide, Some are curved, etcetera. Some are really small, someone really big. So for those, why not know each island on the Galapagos Island has different finches with different beak size. The island chain offers suitable conditions for adaptive radiation to take place as when an organism of a certain species comes to an island together and get disperse all through the chain, and each of these organisms getting settle into distinct niches and exploiting various food resources in order to minimize the competition, thus, resulting into adaptive radiation. So this question is asking, why is it that islands provide a great opportunity for ad after radiation? So, one of most famous examples and biology is gonna be the Galapagos Islands. It usually takes place when an organism enters a novel region and distinct traits influence its survival. ![]()
