Raw material for evolution
Webby the Understanding Evolution team. A mutation is a change in DNA, the hereditary material of life. An organism’s DNA affects how it looks, how it behaves, and its physiology. So a … WebAs we explored in Formation of our Solar System, the raw materials for life all ultimately came from space. The early Universe was composed mostly of hydrogen, with a little helium and lithium, as well as trace amounts of heavier elements. Successive generations of stars have processed hydrogen into heavier elements. Through nuclear fusion in
