The insulin used to treat people with diabetes is commonly produced by inserting the dna sequence for human insulin into a bacterium. the insulin the bacterium produces using that sequence is then harvested. in fact, dna sequences from virtually any living organism could be inserted into a bacterium and the bacterium would be able to use the sequences to make the same proteins that the original organism did. in what way does this provide evidence for evolution? since bacteria are able to use dna from other organisms, they must have evolved from them as a common descendant. bacteria must be less evolved than higher organisms since they can still make proteins from the dna of other organisms. since the genetic code is the same across species, these species must have inherited it from a common ancestor. since foreign dna was added to the bacteria, it evolved beyond higher organisms.

Up until 1938, paleontologists accepted the idea that coelacanths (an ancient fish) went extinct at the time that they last appear in the fossil record, about 80 million years ago. but in 1938, a live coelacanth was discovered off the coast of south africa that was compared to the fossil record and found to be the same species what goal of science does this discovery represent
