ET theory on origin of life
LIFE began when meteorites bombarded “warm little ponds” on Earth’s surface, scientists say.
Experts once thought the first creatures originated from volcanic ocean vents four billion years ago.
But research by Canada’s McMaster University and Germany’s Max Planck Institute backs Charles Darwin’s 1871 theory that life began earlier in “warm little ponds with ammonia and phosphoric salts, light, heat, electricity present”. Ammonia and hydrogen cyanide would create RNA, a building block of life.
