Frequently Asked Questions
What is the theory of panspermia?
Panspermia is the idea that life was created in space or on another planet and the seeds of life dispersed to new worlds.
What do comets deliver that is related to the origin of life?
Comets deliver building blocks of life, including water, dust, carbon dioxide, methanol, and ammonia.
What is Shastak's goal in his research on the origins of life?
Shastak aims to create a simple self-replicating RNA molecule that could eventually form a simple cell capable of duplicating itself.
