Mankind has always wondered how and why they came to be. Upon further discoveries throughout time from modern humans‚ the majority of scientists would agree that man evolved from a common ancestor in the span of thousands of years. In recent human history some people would suggest that humans have stopped evolving due to advancements in technology and medicine. Even though humans have certainly gained more knowledge‚ there are still forces of evolution that cannot be stopped. These forces include;

within domesticated species and within species throughout the natural world. Variations in colors‚ structures‚ organs‚ and physical traits differentiate a multitude of species from one another. Heredity is the mechanism that perpetuates variations‚ Darwin argues‚ as traits are passed from parents to offspring. What is important about these variations to Darwin‚ though‚ is the way they allow species to adapt and survive in the natural world. He gives numerous examples of variations that illustrate

Artificial selection in domesticated pigeons and natural selection in wild finches have similar aspects as well as many differences due to the type of selection that occurred. Evolution is the idea that all life on earth shares a common ancestor. Natural selection is the survival and reproduction of traits that are best suited for their environment (Schab‚ 2017). Artificial selection is intentionally selecting traits that are desirable for reproduction. The passing of traits from one generation to

Charles Darwin revolutionized biology when he introduced The Origin of Species by Means of Natural Selection in 1859. Although Wallace had also came upon this revelation shortly before Origins was published‚ Darwin had long been in development of this theory. Wallace amicably relinquished the idea to Darwin‚ allowing him to become the first pioneer of evolution. Darwin was not driven to publish his finding‚ which he’d been collecting for several years before Wallace struck upon it‚ because he had

forces of evolution include mutation‚ gene flow‚ genetic drift‚ and natural selection. Mutation is when there is a change occurs in a gene or chromosome structure which results in a difference in a physical or behavior trait. This trait can be carried into the next generation because the trait is contained in the gene. Gene flow is the process of genes transferring from one population to another. Genes can be transferred to different populations by migration of individuals along with the genetic material
