Unveiling the Mystery of How Earth's Earliest Animals Evolved
Scientists recently discovered evidence which suggests that the earliest animals on Earth evolved millions of years earlier than previously thought. According to a new study published in the journal Nature, the first animals appeared on Earth 635 million years ago, during the Ediacaran period. This is much earlier than the previously accepted date of 541 million years ago, during the Cambrian period. The new discovery is the result of a global effort to identify fossils from this period of Earth’s history.
