Dinosaurs didn't survive due to a catastrophic event that altered the Earth's environment significantly. The prevailing theory suggests a massive asteroid impact, leading to drastic climate changes, including blocking sunlight and causing global temperatures to plummet. This event, occurring approximately 66 million years ago, made survival impossible for dinosaurs, but some species evolved into birds, offering a lineage of survival from that era.

FAQs & Answers

  1. What caused the extinction of dinosaurs? The extinction of dinosaurs was primarily caused by a massive asteroid impact around 66 million years ago, which triggered drastic climate changes leading to their demise.
  2. Did any dinosaurs survive the extinction event? While non-avian dinosaurs went extinct, some species evolved into birds, which are considered modern-day descendants of dinosaurs.
  3. How did the asteroid impact affect Earth's climate? The asteroid impact blocked sunlight, causing global temperatures to drop significantly, disrupting ecosystems and making survival impossible for many species including dinosaurs.
