Scientists Find Oldest Seaweeds
In rock from Chitrakoot in Central India, scientists from The Swedish Museum of Natural History have discovered 1.6-billion-year-old remains of multicellular red algae, making them the oldest known plant-like fossils. The find shows that multicellular life originated much earlier than thought. The first evidence of mono-cellular life on Earth is 3.5+ billion years old, but current knowledge says larger organisms did not evolve until 600 million years ago. So, the ancient red algae force scientists to alter their theories about evolution.
