The first mammals
If you haven't seen anyone and have no clue about how they might have looked, could you draw a picture of them? Scientists recently recreated how the first mammals to have walked the earth, would have looked like. Millions of years after they even existed!
What an amazing feat.
They also say that probably all the dinosaurs disappeared from the earth due to a meteor collision with earth. This allowed other animals- mammals to thrive on earth.
