Creature that lived more than 555 million years ago is the 'oldest ancestor of all living creatures'

The video discusses the discovery of a tiny worm-like creature, Caria Wariota, which lived 555 million years ago. Found in South Australia, this creature is considered the earliest relative of most animal life on Earth. The study, published in the Proceedings of the National Academy of Sciences, reveals that the creature was about the size of a grain of rice and possessed bilateral symmetry, indicating it had a mouth, anus, and gut. This symmetry suggests it could be the first common ancestor to animals with a bilateral body plan, including dinosaurs, insects, and humans. The creature lived on the ocean floor during the Edyakaran period and likely had senses to navigate and find food.
