Charles Darwin's theory of evolution gained widespread acceptance as a description of the origin of species, but there was continued resistance to his views on the significance of natural selection as the mechanism of evolution.Evolutionary ideas came to prominence in the early 19th century with the theory of the transmutation of species put forward by Jean-Baptiste Lamarck.Although many religious groups have found reconciliation of their beliefs with evolution, such as through theistic evolution, other religious groups continue to reject evolutionary explanations in favor of creationism, the belief that the universe and life were created by supernatural forces. S.-centered creation–evolution controversy has become a focal point of perceived conflict between religion and science.Several branches of creationism, including creation science, neo-creationism, and intelligent design, argue that the idea of life being directly designed by a god or intelligence is at least as scientific as evolutionary theory, and should therefore be taught in public education.But current research is finding a far more complex scenario than Darwin could have imagined – particularly in relation to bacteria and single-celled organisms.These simple life forms represent most of Earth's biomass and diversity – not to mention the first two-thirds of the planet's history.The London Artifact is an iron hammer, surrounded by a solid mass of cretaceous rock.

Dr John Dupré, a philosopher of biology at Exeter University, said: "If there is a tree of life it's a small irregular structure growing out of the web of life." More fundamentally recent research suggests the evolution of animals and plants isn't exactly tree-like either.

But in this sesquicentennial anniversary of Among Dawkins's strengths are his command of evolutionary science and his vivid metaphors, his wicked wit, and his ability to present the reader with a thoroughly enjoyable stage performance rather than a classroom lecture. After the opening chapter in which he explains that evolution is both a scientific theory and a fact—both words are suitably defined and analyzed—Dawkins launches into the subject the way Darwin did: with artificial selection, then natural selection.

Few others would write that “tree trunks are standing monuments to futile competition,” or relate that what nontranscribed pseudogenes are useful for is “embarrassing creationists.” One of his visual aids is a photograph of a phylogeny, together with some of its species, tattooed on the back of an Australian graduate student. Here and throughout the book, Dawkins shows that he is an undisputed master in exposition of natural selection and adaptation, which serves him well as he goes about showing how only this theory can account for countless facts of biology that would otherwise be inexplicable (unless one attributed caprice, sadism, or other unappealing properties to a designer).

At first it's very scary – but in the past couple of years people have begun to free their minds." Both he and co-researcher Dr Ford Doolittle stressed that downgrading the tree of life doesn't mean the theory of evolution is wrong just that evolution is not as tidy as we would like to believe.

Dr Doolittle, of California University, said: "We should relax a bit on this.
