Extreme abolitionists did more harm than good because they
tended towards extreme militancy, and with their use of virulent words, the extreme
abolitionists turned off Southerners to their cause. This did more harm than
good, first to the slaves, then also the abolition cause in general.

<span>Evidence for Evolution During and since Darwin's time, people have been looking for and studying evidence in nature that teaches them more about evolution. Some types of evidence, such as fossils and similarities between related living organisms, were used by Darwin to develop his theory of natural selection, and are still used today. Others, such as DNA testing, were not available in Darwin's time, but are used by scientists today to learn more about evolution.<span>Five types of evidence for evolution are discussed in this section: ancient organism remains, fossil layers, similarities among organisms alive today, similarities in DNA, and similarities of embryos. Another important type of evidence that Darwin studied and that is still studied and used today is artificial selection, or breeding.</span><span>
