I think I prefer the articles on evolution on earth because they are imaginative but rooted in some suggestive and stimulating evidence. On the other hand the debates on the possibility of life beyond the Earth tend to be a lot of wind-bags speculating from insufficnet evidence.

formulating a strategy for searching for extraterrestrial life that allows one to push the boundaries of our Earth-centric concepts of life
Yay for aliens.
