Evolution
Today marks Charles Darwin’s 204th birthday. As a naturalist, Charles Darwin had a biology-based curiosity about the world. In his early twenties he embarked on a voyage on the SS Beagle to observe and document the species that he encountered around the world. Throughout this journey he employed his critical thinking skills to help him formulate the Theory of Evolution. His definition of evolution was "descent with modification." However, as science progressed and we discovered DNA, the definition was updated and today it is officially defined as: a change in allele frequencies in a population over time. It's important to note that further advances in science have found data supporting evolution, and so evolution has fulfilled a part of the requirement of a theory, to "stand the test of time." Darwin published his book “On the Origin of Species” in 1859, which has been the flagship of the theory.
