During the stretch of astronomical time sharks have existed, the Solar System has fully orbited the core of the Milky Way twice. Trees (in the form of progynmosperms) would eventually come around, beginning to grow anywhere from 30 to 100 million years after sharks came into existence, but would not bloom for another 230 million years. Us humans have only been wandering the planet for around 300,000 years, making sharks over a thousand times older than us. While sharks have certainly evolved over the years, the prototype of the body plan that would give them an edge was established early on. Not only have sharks as a group been around longer than stars and planets, but some individual species live unbelievably long lives.
