Sharks, older than the rings of Saturn by 50 million years, have remained remarkably unchanged for 450 million years. 🦈 in comparison, the rings of Saturn, estimated to be just a few hundred million years old, are relatively young. The universe's age standards dwarf Saturn's rings, with Earth dating back 4.4 billion years, and Saturn itself around 4.5 billion years. Imagine a distant planet with little life, mostly water and earth, where sharks coexisted with early mollusks and arthropods while plants were beginning to emerge on land. The ancestors of great white sharks might have observed the formation of Saturn's rings if they had telescopes. It's fascinating that sharks have evolved so effectively that they've seen no need for substantial changes throughout their extensive existence - a testament to their incredible adaptation and the notion of "if it's not broken, don't fix it." #terramatters #terramater #amazing #shark #saturn #sharkweek #planet #ocean #wildlife
