What makes the finches on the Galapagos Islands a good example of adaptive radiation?         The thirteen different species of finches developed after there was a mass extinction on the Galapagos Islands.         All thirteen species of finches came from the mainland. However, over time, the finches specialized to their area on the island, and their beaks evolved to help them survive predators.          The finches were native to the islands. Over time, more finches from different areas came to the islands and crossbred with the other species on the island, creating more species of finches.         There are thirteen different species of finches on the Galapagos Islands. All thirteen species of finches share a common ancestor from the mainland. The different species of finches filled the vacant niches on the island and specialized.

Once a mutualistic relationship evolves between two species, will natural selection and co-evolution cause the two species to become continuously more dependent on each other? Or is it possible for one to end the mutualism? Describe.

In 1959 Daniel Yuh set up a long-term study of cataloging the blood types of a group of foragers in the Brazilian rainforest. In 1959 he found there were no individuals with blood type B. Three generations later, after this group had begun exchanging mating partners with another group, there were several members with blood type B.

The mechanisms of evolution that we have learned contributed to the diversity of organisms we have today. We can see these organisms everywhere, even not physically but we learned about them on TV, books, social media, and others. We come to appreciate them and be amazed by their structures, mechanisms of eating, survival and many more. We also learned that we, humans, can be a contributory factor on lessening their diversity potentials and even their survival through hunting, destroying and relocating their habitats. As a member of the community you are living in now and with the remaining diversity of organisms present in your place, identify organisms you think are nearing extinction/endangered or have low diversity. Afterwards, write the reasons for this if you know, or possible reasons if not. Lastly, present a plan on how the community can work together in preserving and encouraging more variation in these organisms in the near future. You can ask help from the elders for their…
