Global warming during a "greenhouse interval" ultimately led to the start of the human race, scientists believe.
New research suggests that sea temperatures of around 25C (77F) and a lack of permanent polar ice sheets fuelled an explosion of species diversity that eventually led to the human race.
Scientists made the discovery while looking for clues in tiny fossil shells in blocks of Shropshire limestone thought to be around 510 million years old.
The timeframe is referred to as the Cambrian explosion, when representatives of all the major animal groups first appeared.
The surge in diversity allowed life to evolve into a multitude of complex forms, including fish, reptiles, birds and mammals.
Scientists previously thought the Cambrian explosion must have been fuelled by warm temperatures, but the evidence has been lacking so far.
This new findings suggest it was a "greenhouse interval" when high levels of carbon dioxide filled the atmosphere and temperatures soared.
The findings appear in the journal Science Advances.

According to my calculations, it started 499,743,339 years ago. Where the heck does this bozo get get off saying 500?

The glaciers melted to give us the world we have now and I know of no factory or car pollution during the ice age to cause such global warming..
Gore predicted global warming would melt the polar ice caps and the ocean rise would create great destruction.I live 2 blocks from the ocean and have noted no such increase.Once in awhile there’s flooding in various places but that’s not anthropogenic global warming.
It’s _the weather_ and we little fleas on the face of the earth are not to blame.
(The ice caps were to have melted by 2013)
More hilarity from the dumba$$es.
Yes, more gore bull warming please!
They are building luxury high rises right on the beach as fast as they can not too far from where I am. One of them put in an underground garage.
Can someone please tell me what is the correct temperature for the earth?
This is wonderful news. Let’s all get in our gas guzzlers and pump out more CO2 and ramp up global warming and start a new Cambrian explosion. Man could sure use more evolution - about time we get a new and improved model.
See!! CO2 bad! or was it good?
What did they use to collect the data 500 million years ago?
Don’t Luddite Get You Down
We’ll have our global warming,
it’s gonna be the rage.
The benefits are forming
to stall the next ice age.
But, hark, what muffled grousing
the transom overflows,
as climate change arouses
funky festooned foes.
It’s a cascade of excresence
to make mankind regress
to living like a peasant
while using less and less.
Crank up the moth-balled factories
and turn the A/C down.
Build nuclear reactors
to light your life and town.
