The Fate Of The Dinosaurs

A large asteroid struck our planet and killed dinosaurs about 66 million years ago, according to archaeological studies.

This theory is widely accepted, but new research shows that the dinosaur population and the various species were in a state of steep decline many million years before the asteroid hit Mexico.

MORE IDEAS FROM Were dinosaurs doomed before the asteroid hit?

  • Crocodiles are lizards are ectothermic(cold-blooded) animals.
  • Humans and birds are endothermic(warm-blooded).
  • Dinosaurs are somewhere in between these two and are classified as mesothermal.

Dinosaurs needed a warm climate to survive, and any sharp temperature decrease could have been fatal for them. Changes in vegetation and climatic deterioration could also be factors in the eventual decline of the dinosaur, paving the way for primates and humans.

The ABCs Of DNA

Your DNA is different from everyone else’s. It determines many of the characteristics that define you, like the color of your eyes or whether your hair is straight or curly.

DNA is much easier to find in the “soft parts” of an animal – their organs, blood vessels, nerves, muscle and fat.

But a dinosaur’s soft parts are long gone. They either decomposed or were eaten by another dinosaur.

Dinosaurs ruled the Earth for 175 million years

Dinosaurs first appeared between 247 and 240 million years ago. An extinction event wiped them out 65,5 million years ago, except for the avian dinosaurs.

Scientists think the extinction was likely because of an asteroid impact, chemicals from erupting volcanoes, climate change and other factors.

Craters On The Moon
  • The 17th century saw Galilieo exploring the moon using his telescope, wondering how craters were formed.
  • Two centuries later, astronomers like Franz von Gruithuisen proposed that asteroids were responsible for the same, a theory that was rejected.
  • The perfect circular shape of the moon’s craters misled scientists into believing these are mountains. Later the Russian astronomer Nikolai Morozov concluded through a series of experiments that the craters were indeed formed by asteroids.
