Evo in the news Unmuddying the Cambrian waters - March, 2016 Any scholar of history knows that the further back in time you go seeking answers, the more sparse and unreliable the clues. Paleontology is the study of the history of life, and its clues — for the most part — take the form of fossils. The fossil record is notoriously incomplete, but in general, we have more direct evidence of life in the recent past than we do of life in the most distant past. It should therefore not be surprising that one of the most studied events in evolution, the Cambrian "explosion" (which started about 542 million years ago and lasted — unlike most explosions — over 10 million years), is also one of the most enigmatic and passionately debated. Can new research bring life of the Cambrian into focus? Read the rest of the story here | See the Evo in the News archive

A Place for Life: A special astronomy exhibit of Understanding Evolution Biology and paleontology provide an increasingly detailed picture of the evolution of life. Natural selection has resulted in a huge range of organisms living in a multitude of environments, and the geological record shows us how the Earth as a whole has changed over time. To understand the stage on which the evolution of life plays out, however, we must turn to astronomy.		CSI: Olduvai Gorge.
