take root: to begin to grow or develop successfully in a place or situation
NASA’s Osiris-Rex spacecraft traveled 2 billion miles to the asteroid Bennu and found the building blocks of life. This discovery supports the idea that asteroids crashed into Earth long ago, delivering materials that helped life take root. Even more exciting is the possibility that other planets may have received the same ingredients!
The asteroid dust contains 14 of the 20 amino acids that living things on Earth use to build proteins. It also has signs of water and carbon. For scientists like Prof. Sara Russell, each grain of dust is a clue. “It’s helping us understand where life may have come from,” she said.
