Starfish possess an evolutionary history spanning nearly half a billion years of life
In short: The familiar starfish has a surprisingly deep evolutionary past. This video explores the origins of their unique body plan, illustrating how even common modern animals carry a biological legacy that stretches back hundreds of millions of years.
Starfish, or sea stars, are not merely simple creatures found on today's beaches; they are the result of an evolutionary journey that began almost 500 million years ago. Their iconic arm-based body plan is a testament to the immense timescales of natural history.
Understanding the development of these echinoderms provides insight into how complex life forms have persisted and adapted throughout geological time. By examining their deep history, we gain a better perspective on the continuity of life on Earth.
