The very most modern discoveries in paleontology--many of them made through the writer and his students--are built-in with rising insights from molecular biology and earth approach technology to forge a large figuring out of the way the organic range that surrounds us got here to be. relocating from Siberia to Namibia to the Bahamas, Knoll indicates how existence and setting have advanced jointly via Earth's heritage. recommendations in biology have assisted in shaping our air and oceans, and, simply as absolutely, environmental switch has encouraged the process evolution, time and again last off possibilities for a few species whereas beginning avenues for others.

Readers move into the sphere to confront fossils, input the lab to parent the interior workings of cells, and alight on Mars to invite how our terrestrial adventure can advisor exploration for all times past our planet. alongside the way in which, Knoll brings us up to date on a few of science's most well liked questions, from the oldest fossils and claims of existence past the Earth to the speculation of worldwide glaciation and Knoll's personal unifying notion of ''permissive ecology.''
