Such evidence is expected to be empirical evidence and interpretable in accordance with the scientific method. Standards for scientific evidence vary according to the field of inquiry, but the strength of scientific evidence is generally based on the results of statistical analysis and the strength of scientific controls.

Objections to evolution have been raised since evolutionary ideas came to prominence in the 19th century. When Charles Darwin published his 1859 book On the Origin of Species, his theory of evolution (the idea that species arose through descent with modification from a single common ancestor in a process driven by natural selection) initially met opposition from scientists with different ...
Yet the scientific evidence for human evolution keeps piling up with many discoveries of ancient bones, stone tools, cave drawings and other evidence of ancient life. For most people, only modern ...
There is a notable difference between the opinion of scientists and that of the general public in the United States. A 2009 poll by Pew Research Center found that "Nearly all scientists (97%) say humans and other living things have evolved over time – 87% say evolution is due to natural processes, such as natural selection. The dominant ...
Evidence from island biogeography has played an important and historic role in the development of evolutionary biology. For purposes of biogeography , islands are divided into two classes. Continental islands are islands like Great Britain , and Japan that have at one time or another been part of a continent.
