It refers to a comprehensive explanation of some aspect of nature that is supported by a vast body of evidence.

e.g  Darwinism is a theory of biological evolution developed by the English naturalist Charles Darwin (1809-1882) and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce.]]> 2016-08-25 01:30:18 UTC https://padlet.com/1500911/lu0pvlppxj76/wish/119728581 1500911 https://padlet.com/1500911/lu0pvlppxj76/wish/119729073 2016-08-25 01:34:15 UTC https://padlet.com/1500911/lu0pvlppxj76/wish/119729073 1500911 https://padlet.com/1500911/lu0pvlppxj76/wish/119729552 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.]]> 2016-08-25 01:38:09 UTC https://padlet.com/1500911/lu0pvlppxj76/wish/119729552 1500911 https://padlet.com/1500911/lu0pvlppxj76/wish/119732741 Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.]]> 2016-08-25 02:12:37 UTC https://padlet.com/1500911/lu0pvlppxj76/wish/119732741
