Dr Dupré said: "There are problems even in that little corner." Having uprooted the tree of unicellular life biologists are now taking their axes to the remaining branches.Dr Bapteste said: "If you don't have a tree of life what does it mean for evolutionary biology.Objections to evolution have been raised since evolutionary ideas came to prominence in the 19th century.When Charles Darwin published his 1859 book On the Origin of Species, his theory of evolution (the idea that species arose through descent with modification from a single common ancestor in a process driven by natural selection) initially met opposition from scientists with different theories, but eventually came to receive overwhelming acceptance in the scientific community.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.

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 intention of “intelligent design” advocates, as revealed in the “wedge” document ( was to replace evolution in science curricula and to recast the sciences generally in a theological framework (Forrest and Gross 2003).

Over the past three decades, biologists and then scientists more generally have become increasingly aware of the threat that creationism, in its many guises, poses not only to science but also to rationalism and evidence-based decisionmaking.

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.

Many of their species swap genes back and forth, or engage in gene duplication, recombination, gene loss or gene transfers from multiple sources.
