In a groundbreaking new study, researchers have discovered a unique and unexpected link between jellyfish, cats, snakes, and astronauts. By studying the evolutionary history of these creatures, the researchers were able to uncover a common ancestor that lived over 600 million years ago. This ancestor is believed to have been the first animal to have evolved a nervous system, making it a crucial step in the evolution of modern animals. The findings of this study could have implications for our understanding of how animals evolved and the development of modern life.
