In this episode, we discuss microfossils, crystals, and more with geoscientist Juan Manuel García-Ruiz. Juan is a Research Professor of the Consejo Superior de Investigaciones Científicas (CSIC) at the University of Granada, where he explores the interconnectivity of crystals and the origins of life.  As an internationally recognized expert in mineral genesis, Juan does extensive fieldwork visiting crystal sites hundreds of thousands of years old – and you would be surprised at what he has discovered… Join us now to find out: What a biosignature is, and what it tells us about different materials. What Juan has found in his work with giant crystals. How researchers measure the age of crystals. The speed at which crystals grow.   To learn more about Juan Manuel García-Ruiz and his work, click here now! Episode also available on Apple Podcast: http://apple.co/30PvU9C
