A new study has been done by New South Wales University in Australia about the emergence of life on Earth. The new theory says that life on Earth may have begun on land rather than sea. The research takes us to the time for the emergence of microbial life on land by 580 million years.
The Pilbara region of Western Australia was analyzed by researchers to look out for evidences to how ancient microbes could have produced a large number of Stromatolites. The stromatolites were discovered in 1970s and these are round, multi-layered mineral structures. Their sizes vary from the size of golf balls to weather balloons. It also represented the oldest evidence of organism to be living on Earth 3.5 billion years ago.
Earlier it was believed that these mineral formations were formed in shallow, salty sea-water. Researchers now have discovered that stromatolites were not formed in salty water but more likely in conditions of hot springs.
