52: The Thing in the Ice
from Bedrock: Earth's Earliest History
Until now, all the clues for ancient life have been microscopic, beyond the realm of sight. Today, that begins to change. Ten years ago, a team of scientists showed the world a weird, lumpy rock that they claimed was the oldest microbial colony. Like a sci-fi movie, this specimen was found under melting ice in the high Arctic, unveiled from 3.7 billion years ago. But is it actually a fossil? Welcome to the debate that has defined my corner of geology. Extra Credit: Check your house for hard water damage, or watch The Thing (1982). Want bonus content? Check out the Patreon!
