Charles Darwin’s theory of evolution by natural selection was his way of explaining adaptation and speciation. This theory gave a reason as to why species “change” over time and explained the process. This was a huge discovery for Darwin because now we know that species are not fixed and are changing. Ethology, the study of animals in their natural environments, also played a role in the development of Darwin’s theory. Konrad Lorenz’s geese imprinting experiment demonstrated that evolution has a way of helping species survive in their environment.
Darwin’s theory is a process that explains adaptation and speciation in a simple way. First, there is some sort of overpopulation in the environment of a species. Resources are limited and food supply is becoming smaller. The less fit animals are dying out. Second, there is a variation in the gene pool that is inherited by the offspring. These genes make the animals more fit to live in the environment. Third, is selection of the genes that help the animals become more fit to produce offspring with the same genes. Lastly, adaptation. …show more content…
Darwin’s theory, to put in simple terms, is a competition for the more fit species. For example, the peppered moth. The white moths could hide better from predators than the black moths against the lighter trees. The white moths are considered more fit than the black moths. When the trees started to be covered in black coal dust, the white moths were dying out because of the inability to hide from predators making the black moths the more fit species. Some misconceptions about natural selection is that it is random, and that evolution only occurs in the past. Both of these thoughts about natural selection are false. Natural selection is not random, there is a purpose for a change in a species. Also, evolution does not just happen in the past, it is on going even in today's
