Charles Darwin's Theory Of Natural Selection
Natural Selection
Natural selection is a theory created by Charles Darwin. This theory explains that organisms that are more adapted to their habitat live longer and are more likely to pass on their traits through reproduction. For example, a green tree frog in a green rainforest would be more adapt than a gray tree frog. A green tree frog has the potential to blend in with the green surroundings, but the gray tree frog would be easily spotted by a predator and eaten due to its color and inability to camouflage. Also, an animal with minimal swimming skills would be less adapt to the ocean than fish, sharks and whales because these animals live in the water and use swimming as a tool to scurry away from predators or capture prey. Adaption allows organisms to be better suited to survive in their habitat. …show more content…
As stated previously, the better adapted organisms will mostly reproduce. These organisms are passing those same traits that helped them survive to their offspring but, environments change too. Ultimately, these environmental changes can cause the organisms to adapt new traits and these new traits lead to a new species in time. During Charles Darwin’s trip to the Galapagos islands, he noticed some of the same patterns in birds from his earlier trip in South America. He discovered that these birds possessed different beaks but appeared to be similar overall. He conducted more research on the finches’ beaks and found the birds with beaks that could easily catch food in their location would be more likely to survive and reproduce, passing down their beak shapes to their offspring. The migration of that one species of bird resulted into thirteen different species on the Galapagos islands is an example of adaptive radiation. These birds are known today as Darwin’s
