Volution, the overarching concept that unifies the biological sciences, in fact embraces a plurality of theories and hypotheses.
In evolutionary debates one is apt to hear evolution roughly parceled between the terms "microevolution" and "macroevolution". Microevolution, or change beneath the species level, may be thought of as relatively small scale change in the functional and genetic constituencies of populations of organisms. That this occurs and has been observed is generally undisputed by critics of evolution. What is vigorously challenged, however, is macroevolution. Macroevolution is evolution on the "grand scale" resulting in the origin of higher taxa. Evolution I. Evolution II. Understanding Evolution. Evolution: Online Course for Teachers: Teaching Evolution. Evolution: Online Course for Teachers: SESSION 5 How Did Humans Evolve? Is Evolution Still Happening? At the end of this session you will be familiar with: • Fossil evidence for human evolution • Major fossil groups: Australopithecines, Homo habilis, Homo erectus, Homo neanderthalensis, and Homo sapiens modern and present • Molecular evidence for human evolution • The genetic relationship between humans and our closest living relatives.
Evolution: Videos for Teachers: Evolution Case Studies. 250,000-year-old skull found in Ethiopia. Evolution: Videos for Students: Evolving Ideas. Evolution. The similarities described above are not the only ones scientists have noticed among organisms of different species.
The image to the left shows that embryos of certain species develop almost identically, especially in the early stages. Such physical similarities indicate that there are genetic similarities between the organisms. These similarities can be considered evidence that the organisms shown probably descended from a common ancestor. Science & Technology at Scientific American.com: 15 Answers to Creationist Nonsense -- Opponents of evolution want to make a place for creationism by tearing down real science, but their arguments don't hold up.
When Charles Darwin introduced the theory of evolution through natural selection 143 years ago, the scientists of the day argued over it fiercely, but the massing evidence from paleontology, genetics, zoology, molecular biology and other fields gradually established evolution's truth beyond reasonable doubt.
Today that battle has been won everywhere--except in the public imagination. Embarrassingly, in the 21st century, in the most scientifically advanced nation the world has ever known, creationists can still persuade politicians, judges and ordinary citizens that evolution is a flawed, poorly supported fantasy. They lobby for creationist ideas such as "intelligent design" to be taught as alternatives to evolution in science classrooms. As this article goes to press, the Ohio Board of Education is debating whether to mandate such a change. Some antievolutionists, such as Philip E. Main Page - EvoWiki.
