Microbes on Wall of Mine

Microbes on Wall of Mine

A National Geographic News article reports that colorful deposits inside lava caves, previously thought to be mineral deposits are actually excrement from microbes. These microbes were found in lava tubes in Hawaii, New Mexico and the Azores.


This discovery could help scientists find life on Mars since they now know that not everything that looks like minerals really are minerals. I know this from experience.

I originally mistook the white deposits on the walls of an old mine seen in the photo above as mineral deposits, but they are actually microbes. I talk about this on my cave animals page.

Because caves provide shelter from extreme environmental conditions, scientists think these would be good locations to search for life on other planets. I couldn't agree more.
