New molecular research shows that the first simple forms of animal life, progenitors of creatures small and great, from beetles to humans, may have appeared on Earth more than 1 billion years ago, about twice as early as once widely thought.



The findings, based on chemical clues in living creatures, would mean that long before animal organisms grew bones, shells and spines that left a clear mark in the fossil record, minute creatures crawled or slithered between grains of mud or sand in primordial waters. They had no skeletons to be fossilized and uncovered by paleontologists, not even enough substance to leave detectable burrows and tracks.



But for half a billion years, these cryptic organisms presumably were slowly evolving, diverging into different lineages and finally becoming big and complex enough to leave a profusion of fossils, beginning about 565 million years ago in the late Vendian geological period and extending into the Cambrian periodCambrian period [Lat. Cambria=Wales], first period of the Paleozoic geologic era (see Geologic Timescale, table) extending from approximately 570 to 505 million years ago. It was named by the 19th-century English geologist Adam Sedgwick, who first studied the great sequence of rocks characteristic of the period near Cambria, Wales. During the Cambrian, the continents and seas differed from present day configurations. hope this works for you.

Wow, and by wow, I mean WOW. But, I'm a little intrigued at the 'winged' part, that seems counterintuitive. So go from aquatic animals with gils/fins to wings? There has to be an intermdeiary step, which would be even earlier than this. but, I repeat, WOW.

If you believe in creation theory then Genisis states that on the 5th day God made fishes, fowls, and great whales and one the 6th day created beasts, cattle, every creeping thing, man and woman. So like Sid says, it depends on which theory you believe :)

That would have been some single cell bacteria type thing. not really an animal, but what all live evolved from (if you believe in the evolution theory)

Well since we are considered mammals, then I would have to say that we were.

Unicorns! or atleast that's what I believed when I was 5 years old.

Were there Dragons living along side those Unicorns?
