The Shadow Biosphere: Is There Other Life on Earth?

# The Shadow Biosphere

Josh and Chuck explore a fascinating scientific concept that challenges our entire definition of life itself. What if there's microbial life sharing Earth with us right now that we've never recognized because it doesn't follow the rules we think all living things must follow? The hosts dive into how scientists like researcher Carol Cleland are questioning whether alternative forms of life could exist using different building blocks like silicon instead of carbon, or amino acids we've never encountered, and why places we think are completely barren might be teeming with undiscovered organisms that function in ways we've never imagined.
