Write me a paragraph on how dna mapping is very important to evolution. 20 points

Strong evidence for evolution is found in gene comparisons using molecular biology and fossils. It has been proven that genetic changes are passed on from generation to generation, the new species gradually replacing the older ones. Vestigial features, or parts of the body that no longer perform their original use, are found in several species today. The DNA and gene differences are compared for many species. We even see evidence for this today through artificial selection, as farmers genetically modify livestock by getting two of them to interbreed. The DNA can be traced back to the original source.

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
