We suggest that as the Earth changed physically and chemically over time, its surface conditions allowed for a greater diversity of habitats for life. And these changes operate on geologic timescales ...

Is Earth really exceptional?  A new book seems to reaffirm that notion.  But given the right conditions, primitive life may be a mere byproduct of biophysics.

evolution, and development on Earth were extremely improbable. But a new model says that humans gaining a foothold here wasn’t that difficult — and it’s not outside the realm of possibility that ...
