Life on a Young Planet: The First Three Billion Years of Evolution on Earth

Andrew H. Knoll

Australopithecines, dinosaurs, trilobites--such fossils conjure up pictures of misplaced worlds full of vanished organisms. yet within the complete historical past of lifestyles, historical animals, even the trilobites, shape basically the half-billion-year tip of an almost four-billion-year iceberg. Andrew Knoll explores the deep heritage of existence from its origins on a tender planet to the really good Cambrian explosion, providing a compelling new reason behind the emergence of organic novelty.

The very newest discoveries in paleontology--many of them made by means of the writer and his students--are built-in with rising insights from molecular biology and earth approach technology to forge a huge realizing of ways the organic range that surrounds us got here to be. relocating from Siberia to Namibia to the Bahamas, Knoll exhibits how lifestyles and atmosphere have developed jointly via Earth's background. strategies in biology have assisted in shaping our air and oceans, and, simply as without doubt, environmental swap has inspired the process evolution, many times ultimate off possibilities for a few species whereas starting avenues for others.

Readers cross into the sector to confront fossils, input the lab to determine the internal workings of cells, and alight on Mars to invite how our terrestrial adventure can advisor exploration for all times past our planet. alongside the best way, Knoll brings us updated on a few of science's preferred questions, from the oldest fossils and claims of existence past the Earth to the speculation of worldwide glaciation and Knoll's personal unifying inspiration of ''permissive ecology.''

In laying naked Earth's private organic roots, existence on a tender Planet is helping us comprehend our personal position within the universe--and our accountability as stewards of a global 4 billion years within the making.

In a brand new preface, Knoll describes how the sphere has broadened and deepened within the decade because the book’s unique e-book.
