Darwin’s theory of biological evolution tells us that all life on earth may have originated from a single, relatively simple reproducing creature living in the distant past. This idea is based on many observations, one of which is that when living things reproduce, children are often born with random new traits.The theory of evolution by natural selection gained rapid acceptance among biologists after Darwin published it in 1859, in part because it was so successful in explaining what we see in the fossil record. The theory of evolution has gained even further support since that time, because it has successfully passed many other observational tests.These findings led to the formation of the modern cell theory, which has three main additions: first, that DNA is passed between cells during cell division; second, that the cells of all organisms within a similar species are mostly the same, both structurally and chemically; and finally, that energy flow occurs within cells.Jul 1, 2015 · Perceptions of scientific consensus on evolution tend to vary by education and science knowledge.
