From playing with dinosaurs as a kid, Jason made it his life’s mission to discover what happened to them. He worked hard to become the world’s most renowned paleontologist. He might not have had the technology to take Dino DNA out of the mosquito like John Hammond. Still, he hit the jackpot when he saw the colossal impact cavity along the coast of Mexico’s Yucatán Peninsula. He saw something no one else did—the presence of an early version of human DNA. The meteor had delivered humans to Earth and eradicated the magnificent mammals. We had killed them.
