What is evolution? Evolution in the broadest sense explains that what we see today is different from what existed in the past. Galaxies, stars, the solar system, and Earth have changed through time, and so has life on Earth. Biological evolution concerns changes in living things during the history of life on Earth. It explains that living things share common ancestors. Over time, biological processes such as natural selection give rise to new species. Darwin called this process "descent with modification," which remains a good definition of biological evolution today. .
Studies in evolutionary biology have led to the conclusion that human beings arose from ancestral primates. This association was angrily debated among scientists in Darwin's day. But today there is no significant scientific doubt about the close evolutionary relationships among all primates or humans. The theory of evolution explains how life on Earth has changed. In scientific terms, "theory" does not mean "guess" or "hunch" as it does in everyday usage. Scientific theories are explanations of natural phenomena built up logically from testable observations and hypotheses. Biological evolution is the best scientific explanation we have for the enormous range of observations about the living world. Scientists most often use the word "fact" to describe an observation. But scientists can also use fact to mean something that has been tested or observed so many times that there is no longer a compelling reason to keep testing or looking for examples. The occurrence of evolution in this sense is a fact. Scientists no longer question whether descent with modification occurred because the evidence supporting the idea is so strong. .
Humans did not evolve from modern apes, but humans and modern apes shared a common ancestor, a species that no longer exists. Because we share a recent common ancestor with chimpanzees and gorillas, we have many anatomical, genetic, biochemical, and even behavioral similarities with these African great apes.
What is evolution? ... The greater number of offspring left by dark moths is what caused their increase in frequency. ... Evolution also has two subunits which can be divided into micro evolution and macro evolution. The kind of evolution documented above is micro evolution. ... I think the difference between the two is senseless because macro evolution is cumulative micro evolution. ...
Evolution Evolution is the change that species undergo over time. ... Evolution can be found in fossil records and chemical and structural similarities. ... When the changes are so immense as to go beyond what most individuals of a population can endure, death occurs. ... Therefore, evolution will have occurred. ... The most popular piece of evidence for evolution are the fossil records. ...
Evolution The origins of mankind is an extremely controversial issue within today's society. ... One such argument is the conflict involving the theory of evolution versus the theory of creation. After extensive scientific research, it is apparent that the theory of evolution is correct. ... Similarities in these categories link species together and are therefore studied to support evolutionism. ... Darwin proposed that evolution occurred as the result of natural selection. ...
Charles Darwin was the first to bring fourth the idea of evolution. ... Evolution is the most logical explanation for mans place on earth. ... So animals were good because they only did what came naturally. This is why man can be corrupted because he can think about what he is doing and why he is doing it. Animals cannot, they just do what is in there instinct. ...
Scientists spend years solely on the research of evolution theories to provide evidence for evolution. This enables them to present facts and defend evolution as a truth. However, showing clear-cut evidence to a nonscientist that evolution exists still presents a major problem. ... However, many arrogant nonscientists will continue to believe only what has been taught by religions for centuries. ... Archeological fossils have been found that creates some evidence that points to more or less evolution. ...
The Theory of Evolution The theory of evolution creates tremendous controversy in today's society. ... The theory of evolution states that evolving first started with one single celled organism and species slowly progressed into what is now, considered the highest life form. ... Much evidence can be provided against the theory of evolution. But what scientific proof can be offered to eliminate the notion of procreation? ... As a matter of fact, what happened to this supposed "single common ancestor?" ...
