Scientists at the Jet Propulsion Laboratory are studying a rock on Mars that may prove to have once harbored life. The rock, which is over four billion years old, contains orange carbonate grains that could potentially be proof of life on the red planet.
The discovery of possible life or evidence of past life on Mars was announced publicly and quickly spread across the world, generating immense interest and sparking subsequent research.
This podcast explores the idea that all forms of life on Earth, from animals to plants to humans, were once part of a molten ball of magma that gradually cooled down over time, resulting in the creation of our planet as we know it today.
Scientists at the Jet Propulsion Lab conducted a study on Martian rocks found in the Allen Hills of Antarctica to find evidence of microbial life that matched what was exhibited on the ALH84001 rock - an extraordinary claim that required extraordinary evidence according to Carl Sagan.
In this episode, Ben Greenfield and Jonathan Clinthorne discussed the potential uses and benefits of fecal microbiota transplant (FMT), the differences between openbiome and companies like Finch Therapeutics, and how tracking your gut health with gadgets like Viome can influence your fecal transplant decisions.
Three billion years ago, Mars underwent the Great Desiccation Event, while Earth underwent the Great Oxygenation Event, which led to the rise of life on Earth, as Mars became a cold, dusty planet that was no longer being fed by its core, and which caused a thinning atmosphere and a drop in temperatures.
