Hello, this is Lillian. Welcome to Sci Show. Today we’re gonna talk about the origin of life. Where did we come from? Maybe a lightning strike! According to a new study by Yale University, during Earth’s early history, there were about 1 to 5 billion lightning strikes each year. They hit rocks, changing them and dissolving them in water. As a result, lots of phosphorus came out of the rocks. As a key element for life, phosphorus not only helps make DNA and RNA, but also gives energy to cells. There is even phosphorus in your bones and teeth. Thanks for watching. See you next Friday for more wonders!
