It’s hard to imagine Earth without humans but some animals have been around much longer than we have. Sharks, for example, have even survived the 5 major mass extinctions.
Hippopotamus, 16 million years
Hyena, 22 million years
Elephant, 55 million years
Gorilla, 65 million years
Alligator, 80 million years
Turtles, 200-300 million years
Shark, 450 million years
In the past 439 million years, there have been 5 big extinctions and sharks have survived all of them.
