TETRAPODS ("four-footed" vertebrates) originate, as the first amphibians come onto land. In 2006 an amazing transitional form, a 9-foot-long carnivore that looked like a cross between a fish and a crocodile named Tiktaalik (left), was discovered in the Canadian Arctic. It lived 375 million years ago.

1. Four times in the period, (ie, roughly every 100,000 years) the temperature has quickly shot up to 2°C – 3°C above today’s and then slowly slipped back to about 8°C below today’s temperature.

TED Talk Subtitles and Transcript: Did humans evolve from monkeys or from fish? In this enlightening talk, ichthyologist and TED Fellow Prosanta Chakrabarty dispels some hardwired myths about evolution, encouraging us to remember that we’re a small part of a complex, four-billion-year process — and not the end of the line. "We’re not the goal of evolution," Chakrabarty says.
