Two of the three most profound discoveries we have ever made in science have to do with earth history. The three are, in no particular order, 1) the scale of the universe 2) the age of the universe and our home planet, and 3) the unity of life on Earth by descent from common ancestors. This blog invites comments and questions about the last two, how they are perceived by society, and what they imply for what we should be doing as a species.
This blog is for the developers of this proposed web site to test multi user blog capability, and to communicate ideas, Center member needs, and other implementation issues to each other. A Forum is better suited to this type discussion, so we closed this blog and opened several Forum areas for ongoing conversations.
