Fossils aged 1.6 billion. years!

Swedish scientists discovered in central India the oldest on Earth plant form fossils, algae about 1.6 billion years. The startling discovery reinforces the belief that advanced multicellular life developed on Earth much earlier than you normally believed. Researchers at the Swedish Museum of Natural History, led by Professor Emeritus paleozoology Stefan Bengkston, who made the notice published in PLoS Biology journal, found two types of well-preserved fossils in sedimentary rocks in Tsitrakout, which probably derived from red algae (red algae).

“No one can be 100% sure with material as old as it has not been preserved DNA, but the morphology and structure indicate that it is red algae,” said Stefan Bengkston. The oldest traces of life on Earth date back before at least 3.5 billion years old and are simple unicellular microorganisms without cell nucleus. The large multicellular eukaryotes (with a nucleus) appeared in large numbers much later, from about 600 milion years ago.

Unclear remains the in the meantime, that the early multicellular eukaryotes, as far fossil discoveries are sporadic and difficult to interpret with certainty. Until now, the oldest known red algae fossils were aged 1.2 billion years. Indian fossils is therefore 400 million. years old and is clearly that are the most ancient form of plant fossils ever found. The discovery is expected to lead to changes in the first “branches” of the tree of life.
