Birds have appeared sometime around 100 million years ago (give or take, the experts probably have a more precise number), they are the only dinosaurs still alive today, but how did they survive the asteroid? Most birds were wiped out, along with the rest of the dinosaurs and 75% of all life on Earth, but one group of birds made it through and they are still living. Watching the video you can discover how they endured, and which traits made them resilient in the brutal aftermath of the mass extinction event, but you probably know that size and mobility do matter when a meteorite is crashing Earth. Small or smaller size and greater mobility like flying increace your chances of survival.
