Proxima b is a challenge to materialism, according to David Klinghoffer

David Klinghoffer, a Senior Fellow at the Discovery Institute, thinks the discovery of a relatively close, relatively Earth-like planet presents a challenge not only to evolutionary theory (Klinghoffer thinks every new discovery presents a challenge to evolutionary theory), but to any materialist worldview (“Put Up or Shut Up for Evolution? Nearest ‘Habitable’ Planet Found Orbiting Proxima Centauri“):

We’re both fans of Betul Kacar‘s research (see “AbSciCon day 3: the tape of life“). I know why I like it, but I can’t quite figure out why they do. Dr. Kacar’s research combines molecular paleontology with experimental evolution, inserting ancient versions of genes into modern bacteria and observing how they evolve in response.

Martian paleontology

NAISeminarsAt AbSciCon, I wrote about Mars Icebreaker, a proposed NASA mission that would search for signs of past and present life (“AbSciCon day 4: Mars, life, and Mars life“). Before Icebreaker, though, a new rover is scheduled to launch in 2020, with instruments designed to detect past and present biosignatures. Among these is the Planetary Instrument for X-Ray Lithochemistry (PIXL). On Monday at 1:00 PDT, Abigail Allwood from NASA Jet Propulsion Laboratory will be presenting a webcast seminar as part of the NAI Director’s Seminar Series:
