Enzymes are proteins that help speed up chemical reactions in the body. They often work by binding to target molecules. How do you think the sequence of amino acids in an enzyme relates to its ability to bind to a specific target molecule?

Evidence of evolution can be identified through fossil records, testimonial fossils, biography, anatomy, and embryology. An example of a species DNA is the peppered moth, whereby light-colored moths are eaten by birds, unlike the dark colored ones which seem to camouflage on dark backgrounds.  Evolution changes the genetic makeup of a population over time and may happen on a large scale or small scale basis which affects either one of a few genes over a short period.
