Curiosity rover finds proto DNA like molecules on Mars suggesting ancient habitability

Proto DNA like hints raise the odds of life

NASA’s Curiosity rover has detected more than 20 organic molecules, including structures resembling proto-DNA, in Mars’ Gale Crater. Scientists say the chemistry strengthens evidence that Mars once had environments capable of supporting life. Some of the organics may even have been delivered by meteorites, adding a fresh pathway to how life-building materials could arrive and persist.
