The Theory of Evolution was proposed by Charles Darwin in 1859 and discussed how organisms change over the course of many generations and years when physical characteristics change to give a better chance of survival. The idea that species could become different has being around since ancient Greece when philosophers like Anaximander and Empedocles proposed that species can descend into another species. During the dark and middle ages, the power of the Church meant that the materialistic ideas on life was rejected until the 17th century when the scientific method and modern science began. Charles Darwin during his voyage to the Galapagos Islands noticed that finches were similar but also different island to island in order to survive better. Later in 1859, he wrote the important and controversial book “The Origins of Species” that changed how society viewed the past.
Evidence supporting the Theory of Evolution is found in many areas of science. Anatomy, molecular biology, biogeography, fossils and direct observations all work together to support the Theory of Evolution.
Biochemical Evidence

Although the biological cells are quite different from organism to another but on the molecular level are very similar in molecular and chemical makeup. The same molecule, for example adenosine triphosphate, is vital in all present life forms to power cellular activities. Genes in primates and humans only differ by 1 to 2 percent and amino acids, DNA and RNA are also present in all species, suggesting a common background. Similarities in the biochemistry of different species is evidence for the Theory of Evolution because it shows that all species are related to each other. Many molecular fossils found over the years have revealed that they are very similar to nucleic
