Evidence of Evolution. The evidence for evolution is compelling and extensive. Looking at every level of organization in living systems, biologists see the signature of past and present evolution. Darwin dedicated a large portion of his book, On the Origin of Species, to identifying patterns in nature that were consistent with evolution. Since Darwin, our understanding has become clearer and broader.

Comparative Anatomy. Vestigial structures are another class of anatomical features that provide evidence for common ancestry and evolution. Vestigial structures serve no apparent purpose in species that possess them at present, but may have been important in their ancestors. For example, whales have hip bones, but they don’t need them,

The Evidence for Evolution is the body of observations and experimental results that collectively support the modern theory of biological evolution.

The strongest scientific evidence against evolution: "Evolution" mixes two things together, one real, one imaginary.
