Hundreds of millions of years ago the earth was so harsh ice age, that scientists call that early in the planet snow earth. The geological evidence that ice was everywhere, always to the equator to the brim.
Freezing happens fast. Only in a few thousand years to about 720 million years ago, the blue planet had turned white. Giant snow ball melt until about 635 million years ago.
One of the researchers a lot of thinking about my question is, how in the ocean of lies you primitive life may continue under such circumstances. Kandalaisen Mcgill university (you move to another service) in a fresh research has the answer: clematis were glaciers sulavesi you.
– Geological evidence on the basis of a large part of the ocean was uninhabitable, because they had no oxygen, but some regions of the country on top of the water slid the ice provides crucial oxygen-rich sulavesi, said sediment without Maxwell lecht is .the air bubbles melt oxygen
the Evidence found in the ice age glaciers left behind the iron-rich stone from Australia, Namibia and California.
Rock chemical analyses the researchers were able to assess the amount of oxygen in the sea about 700 million years ago and its impact on the most primitive of sponges and other that the time the fathers of the organisms.
the Ice in the ice the air bubbles were released upon melting of oxygen in the sea, PNAS scientific journal (you move to another service) published research to explain.
Earlier hypotheses according to the organisms survived only glaciers on top of well-oxygenated ponds.
the earth the thorough freezing before complex life forms development suggests that the harsh feeling had eventually a favourable impact on the evolution of diversity, lecht will be assessed.
the Mere oxygen is tieteenkään enough to keep the life above, but also nutrition. Lecht is the planned research, where the ancient food web of the formation were to be traced to this day in the icy environment of complex ecosystems.Also melting revolutionize the conditions
After the snow the earth begins to melt, the sea flooded the continent, revolutionizing the shore line and contributed fundamentally to the development of life. Phase lasted much longer than has been assumed, says another recent study.
the Planet surface practically completely rewritten. Beaches, deserts, rivers and flood plains. Life critical systems recovery takes up to a million years, told the australian Curtinin university (you move to another service) research led geology Adam Nordsveen .
Terra Nova (you move to another service) in the journal the published study was a lot of talk about the sediment of the formation of the sea the bottom of the snow-ball after the season.
Earlier, according to the understanding of sedimentary äärinen carbonate rocks form less than ten thousand years, when the whole earth covered ice melted and sea level rose.
a New study stretch the time period of several hundreds of thousands or even millions of years. Thus, the upheavals were greater than has been assumed, Nordsveen said.
the sediment without Milo Barhamin according to these results might have significant effects on the perception of life diversification of the.
