The theory of evolution‚ formalized by Charles Darwin‚ is as much theory as is the theory of gravity‚ or the theory of relativity. Unlike theories of physics‚ biological theories‚ and especially evolution‚ have been argued long and hard in socio-political arenas. Even today‚ evolution is not often taught in primary schools. However‚ evolution is the binding force of all biological research. It is the unifying theme. In paleontology‚ evolution gives workers a powerful way to organize the remains of

Journal 2 I have always been interested in evolution‚ probably due to my innate inability to accept what people say on “face value”. I believe (as I have taught my children) to question anything and everything which would explain my passion and interest in the evolution of psychology. Evolutionary psychologists use various methods to study how evolution affects psychology. Deductive and comparative methods are the two most commonly used methods because they allow psychologists to study something

relationship with those of America‚ though separated from that continent by an open space of ocean‚ between 500 and 600 miles in width." At this early stage of his life‚ along with graduating college Darwin soon began collecting evidence for his theory of Evolution and natural selection. While on his journey Darwin made many observations. They were mainly about the different species he saw on the Galapagos Islands. Each island had a different variation of birds. He noticed that the beak sizes of the

Evolution of Polar Bears The observed fossil transitions that inform our knowledge of Polar Bear speciation are very well documented. Bear fossils change through time: generally‚ when examining the fossil record‚ successively deeper levels of sediments or sedimentary rocks yield successively older fossils. For some transitions from one species to another‚ one can find a well-characterized series of transitional specimens leading the observer across the species "boundaries" (Kurten‚ 1976). Sometime

1866 Mendel’s paper is published: units of inheritance in pairs; dominance and recessiveness; equal segregation; independent assortment. These ideas are not recognized for 34 years. 1869 DNA (first called "nuclein") is identified by Friedrich Miescher as an acidic substance found in cell nuclei. The significance of DNA is not appreciated for over 70 years. 1900 Mendel’s experiments from 1866 are "rediscovered" and confirmed by three separate researchers (one Dutch‚ one German‚ one Austrian).

Evolution in biology is a genetic change in a line of descent over time. The evolution of life on Earth has resulted in many hundreds of thousands of species. Genetic evidence reveals that humans share a common ancestor with life forms as different from us as bacteria and corn plants. In early 1800s‚ the source of Earth’s remarkable diversity of life forms was hotly disputed. Many people believed that all species had come into existence at the same time in the distant past. In 1831 Charles Darwin
