  • Hello! My name is Charles Darwin and I am a English naturalist, geologist and biologist! I am best known for my contributions to the science of evolution. In which I will be guiding you through my Theory of Natural Selection.
  • Natural Selection
  • My theory was“It is not the strongest of the species that survives, nor the most intelligent; it is the one most adaptable to change.” This was the theory of natural selection saying organisms better adapted to their environment tend to survive and produce more offspring
  • Today, for our comic strip, we will be using rhinos and their horns as an example of Charles Darwin's theory, natural selection.
  • Rhinos have large horns on their heads. Some have always had their horns for self defense but others who did not, ended up being killed by a predator. So the only ones left were the one with horns which explains why they all have horns today.
  • The gene/trait that provides self defense for the rhinos is the horn. The better adapted rhinos pass on the gene/trait that provides them the defensive horn. So these traits are heritable. This explains heritability.
  • This is the end to our natural selection journey, ending with the natural selection of non-horned rhinos, giving the horned rhinos the dominant feature.
  • With the large horns comes protection and safety of the organism. This gives the rhino with horns a reproductive advantage, and the ones without horns a disadvantage.
  • With the certain rhinos portraying this individual appearance, it creates variability in the populations. Only a certain amount have the horn and some don't. This is an example of variation in natural selection.
  • In conclusion, Natural Selection comes to help organisms adapt and survive in their environment using variation, reproductive advantage, and heritability. And in this example, it is the Rhinos, who came out on top depending on the horn situation.
