The video about the Galapagos Islands that we viewed in class was, very informative. This video was enjoyable and showed very good examples of Darwin’s theory of evolution. The various examples of evolution were shown through the many unique species that live on the Galapagos Islands, such as the saddle-back tortoise. In fact, Darwin actually traveled around South America and the Galapagos Islands themselves. He also discovered that the animals that lived on the islands seemed to be made to adapt to the environments around them, rather than just being made to survive in one, unchanging environment. An example of this, is with the different species of mockingbirds that are located on the different islands. The mockingbirds’ beaks differ…show more content…
The size of the seeds that are plentiful in a certain year, determine whether small beaked birds or large beaked birds make up a bigger part of the population. In other words, if smaller seeds are more plentiful, the smaller beaked birds will make up a greater percentage of the population, because the species adapted to the environment around them. As a matter of fact, these birds live on an island called Daphne Major, which is known as a laboratory of evolution. This video explored Darwin’s theories, while also highlighting the beauty of an area in the world, where unique animals are located. It is also explained in the video, that all of the animals on the different islands started from their own ancestors and eventually became many different species by adapting to the environments over time. Darwin’s discovery of an endemic species was also mentioned in the video. An endemic species is one that is only grown in a certain place. The endemic species that Darwin found was a plant, which is only native to the Galapagos Islands. Overall, this video highlighted the theory of evolution, as well as natural selection. The example of natural selection is shown through the traits of birds being determined by the conditions on the surrounding
