This article is interesting not only for its main assertion, expressed in its title, but for its illustration of the drawbacks of scientific “compartmentalization” and of the benefits that can accrue when scientists from divergent fields talk seriously to one another:
Here’s an additional related and partially overlapping article:
Such research also suggests that certain forms or types of exoplanetary life might be more difficult to detect than many had previously assumed.
