Darwin, of course. Lamarck did not have the evidence to back up his acquired characteristics and use and disuse concepts, but Darwin had massive amounts of evidence and well structured arguments for his theory of natural selection.

Is the Darwin theory of evolution true?

We don't use the word "true" to describe scientific theories. They either fit the facts or they do not. Darwin's theory of evolution fits most of the observed facts, and does so beautifully. A theory is useful if it makes successful predictions. Darwin's theory has absolutely zero to do with belief in God. The Catholic Church does not hate God, yet endorses the view that evolution has occurred in much the way Charles Darwin described. Is there a scientific theory that better explains the evidence from paleontology, geology, anatomy, and molecular biology? No. Therefore, we provisionally accept the theory of evolution as an accurate depiction of the origin of species. Again, this has nothing to do with whether or not God exists and/or loves you. Evolution is wrong. God is true.


Is Darwin's Theory of Evolution true?

There is plenty of fossil records and observable speciation to provide evidence for Evolution. Within the scientific community there is little to no debate on whether evolution is wrong. No concrete evidence has been provided by anyone to dispute the claims of evolution since its formulation by Darwin, otherwise it would have been discarded through the scientific method.--------------------------------------------------------------------------------------------While the above is right, observation and scientific studies provide evidence and arguments to the theory.


Which of the following did Darwin use to support his theory?

Darwin used various forms of evidence to support his theory of evolution by natural selection, including observations of variation within species, the fossil record, comparative anatomy, and biogeography. His work also drew on principles of population genetics and the idea of descent with modification.


What types of evidence did Darwin use to support his theory of changes over time?

Individual organisms differ, but some of this variation is heritable. Species alive today are descended with modifications from ancestral species that lived in the distant past.

Why are creationists upset with Darwin's theory?

His theory doesn't fit with their ideas. They usually use the Bible to answer questions that science already has or is working on. These are questions that are not scientific questions but ones that are best debated and answered by philosophy.
