Top The Cambrian Explosion Quotes

The Cambrian Explosion Quotes By Carl Sagan

600 million years ago, the monopolizing grip of the algae was broken and an enormous proliferation of new lifeforms emerged, an event called the Cambrian explosion. Life had arisen almost immediately after the origin of the Earth, which suggests that life may be an inevitable chemical process on an Earth-like planet. — Carl Sagan

The Cambrian Explosion Quotes By Michio Kaku

Today biologists believe that during the "Cambrian explosion," about half a billion years ago, nature experimented with a vast array of shapes and forms for tiny, emerging multicellular creatures. Some had spinal cords shaped like an X, Y, or Z. Some had radial symmetry like a starfish. By accident one had a spinal cord shaped like an I, with bilateral symmetry, and it was the ancestor of most mammals on Earth. So in principle the humanoid shape with bilateral symmetry, the same shape that Hollywood uses to depict aliens in space, does not necessarily have to apply to all intelligent life. — Michio Kaku

The Cambrian Explosion Quotes By Nick Lane
