The widely believed belief that all life is connected and descended from a common ancestor is Darwin's Theory of Evolution: birds and bananas, fish and flowers are all related. Darwin's general theory assumes the emergence of life from non-life and emphasizes a "descent with modification" that is completely naturalistic (undirected). That is, sophisticated species organically evolve from simpler forebears over time. In a nutshell, as random genetic mutations arise within an organism's genetic code, the favorable changes are maintained because they assist survival — a process known as "natural selection" — and passed down to the next generation. Beneficial mutations accumulate throughout time, resulting in a whole new organism (not just a variation of the original, but an entirely different creature). While Darwin's Theory of Evolution is a recent concept, the evolutionary mindset is as old as time. Anaximander and other ancient Greek philosophers proposed the evolution of life from non-life and the descent of man from animal. Charles Darwin simply added a convincing mechanism termed "natural selection" to the previous concept. Natural selection acts to maintain and accumulate tiny favorable genetic variations. Assume a species member has obtained a functional advantage (it grew wings and learned to fly). Its descendants would inherit this benefit and pass it forward to their descendants. Darwin's Theory of Evolution is a slow gradual process.
Who is Charles Darwin?
mechanical vibrations such as waves observed on the surface of water have been looked upon as an oddity since time immemorial, since the way that the waves are actually formed has been a mystery to most people. today, however, from work done by past researchers, there is a vast practical knowledge accumulated concerning mechanical vibrations, also known as wave phenomena
