(from Science News, January 16, 2021) "Earth is the only known world with plate tectonics. It's also the only one known to harbor life." It is a long article about plate tectonics and the history of its discovery and proof. But, the part I want to point out is "Crucible of Life" about half-way down the screen. I have never heard this before and do not know if it is a new idea or not. The thought is that life "might have" or 'perhaps could have" started with the movement of plate tectonics. Subduction plates grinding stones and with the heating releasing carbon. From there we acquire carbon dioxide and other nutrients necessary for life. But thrown into the midst of that talk is a contradiction saying life may have existed before plate tectonics. Has anyone heard more about this? Or, if you have read the article, what are your thoughts about it? hazelm Quote Link to comment Share on other sites More sharing options...
