Hoover makes several claims to show that a non-biotic origin for these structures is very unlikely. I am not an expert and won’t cast my vote either way here. This is not the first time Hoover has made such claims; he gave a similar presentation in 2007. There have also been many similar claims in the past. In fact, in the second episode of "Bad Universe" I interviewed NASA astrobiologist Dave McKay, who has also found very interesting features in a Mars meteorite that look a lot like bacteria. However, definitive proof is another matter. McKay’s opinion is that what he found was once alive, but he also was clear that scientifically he could not be sure (I found his skepticism to be well-grounded and at the right level, to be honest)....

So, to conclude: a claim has been made about micro-fossils in a meteorite. The claims are interesting, the pictures intriguing, but we are a long, long way from knowing whether the claim is valid or not! We’ve been down this road before and been disappointed. As with any scientific claim, skepticism is needed, and in the case of extraordinary claims, well, you know the saying.

Interesting none the less.
