CNN —An international team of scientists say they have new insight into how the very earliest animals survived after traces of what they described as the world’s oldest meal were found in a 550 million-year-old fossil. Some of the oldest life on Earth is referred to as the Ediacaran biota. This group is based on the earliest fossils ever discovered, providing evidence of complex, multicellular organisms. Nearly all fossils that came before the Ediacaran biota were single-celled and microscopic in size,” Brocks said, according to a press release. Dr. Bobrovskiy said the findings are helping scientists track the evolution of the earliest animals, and how they relate to their descendants today.
