What is Natural Selection? It was discovered by Charles Darwin and Alfred Russel Wallace though Darwin championed the idea in his book . By carefully observing populations of living things with short life cycles you can actually watch it happen.

Darwin's Theory Of Evolution. Darwin's Theory of Evolution - The Premise. Darwin's Theory of Evolution is the widely held notion that all life is related and has descended from a common ancestor: the birds and the bananas, the fishes and the flowers - - all related. Darwin's general theory presumes the development of life from non- life and stresses a purely naturalistic (undirected) . That is, complex creatures evolve from more simplistic ancestors naturally over time. In a nutshell, as random genetic mutations occur within an organism's genetic code, the beneficial mutations are preserved because they aid survival - - a process known as . Over time, beneficial mutations accumulate and the result is an entirely different organism (not just a variation of the original, but an entirely different creature).
Natural Selection Activity
Ancient Greek philosophers such as Anaximander postulated the development of life from non- life and the evolutionary descent of man from animal. Charles Darwin simply brought something new to the old philosophy - - a plausible mechanism called . Suppose a member of a species developed a functional advantage (it grew wings and learned to fly). Its offspring would inherit that advantage and pass it on to their offspring. The inferior (disadvantaged) members of the same species would gradually die out, leaving only the superior (advantaged) members of the species. Natural selection is the preservation of a functional advantage that enables a species to compete better in the wild. Natural selection is the naturalistic equivalent to domestic breeding.
Over the centuries, human breeders have produced dramatic changes in domestic animal populations by selecting individuals to breed. Breeders eliminate undesirable traits gradually over time.
Similarly, natural selection eliminates inferior species gradually over time. An irreducibly complex system is one composed of multiple parts, all of which are necessary for the system to function. If even one part is missing, the entire system will fail to function. Every individual part is integral. The common mousetrap is an everyday non- biological example of irreducible complexity. It is composed of five basic parts: a catch (to hold the bait), a powerful spring, a thin rod called .
If any one of these parts is missing, the mechanism will not work. Each individual part is integral. The mousetrap is irreducibly complex. We now know that there are in fact tens of thousands of irreducibly complex systems on the cellular level. Specified complexity pervades the microscopic biological world.
Darwin and Natural Selection. Most educated people in Europe and the Americas during the 19th century had their first full exposure to the concept of evolution. Darwin's Theory Of Evolution - What claims did Darwin make. How do they stand up to the latest arguments and evidences? Darwinism is a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others, stating that all species of organisms arise. Natural Selection - its power compared with man's selection - its power on characters of trifling importance - its power at all ages and on both sexes - Sexual. Great Natural Products.

Natural selection is a very efficient, predictable mechanism of evolution, illustrating: how species adapt to their environment. Evolution in organisms occurs through changes in heritable traits—the inherited characteristics of an organism. In humans, for example, eye colour is an inherited.
Molecular biologist Michael Denton wrote, . The eye, the ear and the heart are all examples of irreducible complexity, though they were not recognized as such in Darwin's day.
