Introduction. Scientific and technological advances have had profound effects on human life. In the 19th century, most families could expect to lose one or more children to disease. Today, in the United States and other developed countries, the death of a child from disease is uncommon. Every day we rely on technologies made possible through ...The science of evolution At the heart of evolutionary theory are the basic ideas that life has changed over time and that different species share common ancestors. Overwhelming evidence supports these facts. Scientists continue to argue about details of evolution, but the question of whether or not different species are related through a long, shared e. Evolutionary thought, the recognition that species change over time and the perceived understanding of how such processes work, has roots in antiquity—in the ideas of the ancient Greeks, Romans, Chinese, Church Fathers as well as in medieval Islamic science. With the beginnings of modern biological taxonomy in the late 17th century, two ... ….
