Big Bang Theory Darwinism Charles Darwin in 1868 Darwinism is a theory of biological evolution developed by Charles Darwin and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce. Also called Darwinian theory. It originally included the broad concepts of transmutation of species or of evolution which gained general scientific acceptance when Charles Darwin published On the Origin of Species, including concepts which predated Darwin's theories, but subsequently referred to specific concepts of natural selection, the Weismann barrier or in genetics the central dogma of molecular biology.[1] Though it usually refers strictly to biological evolution, the term has been used by creationists to refer to the origin of life, and has even been applied to concepts of cosmic evolution, both fields which have no connection to Darwin's work. Conceptions of Darwinism[edit]
Darwin's theory - Charles Darwin The premise of Darwin's theory of evolution by natural selection is that all life, from mammals to single celled organisms, is related through descent with modification from common ancestral stock. The mechanism he proposed to explain descent with modification was natural selection. Natural selection: the engine of evolution Darwin unveiled his theory in 1859 in his book On the Origin of Species by Means of Natural Selection. Darwin's arrival on the Galapagos Islands Living proof It was during Darwin's journeys on the British survey ship HMS Beagle that he saw the variations in different species that led him to develop the idea of natural selection. The species on these islands - birds, plants, insects and reptiles - resembled those on the South American mainland, but they were also different in many subtle ways.

History - Charles Darwin Darwin's Theory of Evolution: Did Man Really Evolve from Apes Charles Darwin’s theories on evolution upended the scientific community in the middle of the 19th century. He proposed that small changes over billions of years created the species we have today. Darwin felt that it was a “survival of the fittest”. Species that could adapt to their changing environment most effectively would survive, while the weaker genetic lines of species died off. Did you learn Darwin’s theories in high school science class? The main critics of Darwin’s theory of evolution are the supporters of creationism. This debate affects a majority of the American public as it is taught in the public school system. Why not listen to Charles Darwin himself? Want to learn both sides of the Darwin issue?

THE BIG BANG Chris LaRocco and Blair Rothstein present: The Hubble Telescope's deepest view of the universe teaches us about the beginning We certainly know that our universe exists, however, this knowledge alone has not satisfied mankind's quest for further understanding. Our curiosity has led us to question our place in this universe and furthermore, the place of the universe itself. Throughout time we have asked ourselves these questions: How did our universe begin? How old is our universe? We have, however, come a long way from the mystical beginnings of the study of cosmology and the origins of the universe. Although in this short chapter it will be impossible to tackle all of the questions concerning the creation of everything we know as reality, an attempt will be made to address certain fundamental questions of our being. One of the most persistently asked questions has been: How was the universe created? The origin of the Big Bang theory can be credited to Edwin Hubble.
Charles Darwin: The Theory of Evolution Quotes from Charles Darwin (1809 - 1882) on Evolution, Natural Selection, Science, Humanity, God & Religion I have called this principle, by which each slight variation, if useful, is preserved, by the term Natural Selection. (Charles Darwin) Ignorance more frequently begets confidence than does knowledge: it is those who know little, not those who know much, who so positively assert that this or that problem will never be solved by science. (Charles Darwin, Introduction to The Descent of Man, 1871) Introduction: On the Philosophy & Metaphysics of Charles Darwin's Theory of Evolution For thousands of years many philosophers had argued that life must have been created by a supernatural being / creator / God due to the incredible complexity of Nature (in particular, we humans and our minds). Below you will find a brief summary of Charles Darwin's Theory of Evolution and some interesting quotes from Darwin on Evolution, Natural Selection, Science, Humanity, God and Religion. References

Darwin's Theory Darwin's Theory of Evolution Scientists at the beginning of the 1800s know of some kinds of fossils, and they were very aware of homologous and vestigial structures. Many scientists suspected that some kind of evolution had given rise to living things around them. However, they had no unifying theory to explain how evolution might have occurred. Two scientists led the way in the search for a mechanism of evolution. The first was Jean Lamarck. Evolutionary Theory Before Darwin The first systematic presentation of evolution was put forth by the French scientist Jean Baptiste de Lamarck (1774-1829) in 1809. Assume that there were salamanders living in some grasslands. Darwin's Background Charles Darwin (1809-1882), like many people of genius, did not at first appear to have extraordinary talents.

Creation Versus Evolution Questions Someone Always Asks about the Bible’s Creation Account Before we go on, we would like to answer some questions that always seem to come up. One involves how pairs of all the animals could have been collected by one family. Remember, if God is really God, he could have caused the flood, a supernatural event, to occur. Does it not also make sense that God could cause pairs of animals to migrate to the location of the ark? The next question is, how did all those animals fit on the ark? Now, what about dinosaurs, were they on the ark and could they fit? What makes the flood important to our topic is all the evidence it left around. If you have flown on a plane, you probably noticed how different mountains look from the air than they do from the ground. The Evidence As “evidence” to support their theory, most books on evolution include a reference list (bibliography) of other books and articles that also support the theory of evolution. So, How Do I Get to the Facts? Important
