Evolution is the change in allele frequency over time in a population of organisms. By sequencing genes one can see this happen. Also just observing the morphological and behavioral changes in populations over time can lead to evidence supporting evolution. Check Lenski and his E. coli experiments. Over 20 years evolution was observed in these microorganisms. Fairly easy Google.

What type of reason was used to develop the evolutionary theory?
Charles Darwin was one of the first influential scientists to support the evolution theory. On his voyages he came across the Galapagos islands which had a group of birds. He noticed that although these birds were of the same species at first, that they having been separated across the islands, developed different characteristics and soon were no longer able to interbreed. This was the start of the theory of evolution for Charles Darwin as he explained their change of characteristics by saying that they evolved.
Why are vestigial proof of evolution?
Evidence, not proof. Scientists do not prove things. Your coccyx for one bit of evidence, This is the " stump " of a vestigial tail that is now used for another purpose in humans; to help with sitting. Sometimes this tail does grow out in child development. This is evidence of the concept of evolutionary common ancestry.
How can comparative anatomy provide support for the theory of evolution?
1. The adherence of anatomical traits to the nested hierarchies of biology confirms common ancestry in general. 2. Assays of anatomical traits can be used to formulate new phylogenies or refine/confirm existing phylogenies.
Which scientists is credited with developing the system of grouping organisms that is still used today?
Linnaeus
What is evolution and how does it works?
Evolution is the process by which species of organisms change over generations through the inheritance of genetic traits, leading to the development of new species. It works through mechanisms such as natural selection, genetic drift, and gene flow, which drive changes in the genetic makeup of populations over time in response to environmental pressures.
How might the theory of evolution be used by scientists in their studies?
to explain the relationship
How is DNA utilized as evidence to support the theory of evolution?
DNA is used as evidence to support the theory of evolution by comparing the genetic similarities and differences between different species. By analyzing the DNA sequences of organisms, scientists can trace evolutionary relationships and determine how species have evolved over time. This genetic evidence provides strong support for the idea that all living things are related and have evolved from a common ancestor.
When evolution was first proposed what was used as evidence to support this idea?
Fossil records, anatomical similarities among different species, and the observation of natural selection in action were some of the key pieces of evidence used to support the idea of evolution when it was first proposed.
What are some clues scientists use as evidencece for evolution?
DNA can be used to match two species and determine if they are related or share a common ancestor. In addition, the existence of DNA itself is proof for evolution on a large scale - virtually all organisms share the same nucleic acid as the genetic code, leading scientists to the conclusion that all species shared a common ancestor at one time.
What type of reasoning was used in the development of evolution theory?
Inductive reasoning was used in the development of the theory of evolution. Scientists observed patterns in the natural world, collected data from various sources, and then formulated hypotheses based on these observations. Over time, as more evidence was gathered, the theory of evolution was refined and confirmed through further experimentation and observation.
How are fossils used to oppose the theory of evolution?
Fossils are not used to oppose the theory of evolution. They acutually support it in every way. So far not one fossil has been found that is not exactly where you would expect it to be if evolution were true. As we dig deeper we go further back in time and see by piecing fossils together how organisms evolved over time. Although we don't need fossils to support the fact that evolution is happening, it's a nice bonus to have in support of the theory.
What are the main mechanisms used by secular scientists to explain evolution?
All educated and not ideologically blinded scientists explain evolution by three primary mechanisms. Genetic drift, gene flow and natural selection.I have the feeling you do not know what secular means.
How do scientists know that a new theory is accurate?
Because all of the observations and evidence are used for support.
What are true about evolution?
Some true statements about evolution:Evolution is the best explanation we have for the origin of speciesEvolution is accepted by scientists as factThe Theory of Evolution has contributed enormously to the understanding of BiologyThe Theory of Evolution has been used successfully to predict the discovery of an ancient speciesFor more information, please visit: http://christianity.answers.com/theology/the-story-of-creation
What type of reasoning was used in the developoment of evolution theory?
Inductive reasoning was primarily used in the development of the theory of evolution. Scientists collected and analyzed data from various observations in nature to formulate general principles and make hypotheses about the process of evolution. By studying patterns and evidence, researchers were able to draw logical conclusions about how species change over time.
How are similarities in macromolecules among organisms used as evidence to support evolution?
Similarities in macromolecules, such as DNA and proteins, among different organisms can be used as evidence to support evolution because these similarities can be used to construct phylogenetic trees that show how different species are related to each other. The more similar the macromolecules are between two organisms, the more closely related they are thought to be, indicating a shared evolutionary history. This provides molecular evidence that supports the idea of common ancestry and gradual evolution over time.
What Scientific is the term used for a scientific theory that is generally accepted by an overwhelming number of scientists?
that research and observations support the theorythat research and observations support the theory is the correct answer
