The Implications of Extreme Life

Yesterday (17 February 2017), Victoria Jaggard published a piece for National Geographic entitled "Weird Life Found Trapped in Underground Crystals." (http://news.nationalgeographic.com/2017/02/crystal-caves-mine-microbes-mexico-boston-aaas-aliens-science/) As related in that article, scientists have apparently discovered microbial life within fluid that has been trapped inside of giant crystals for millennia. The crystals were found inside of caves which lie deep beneath the Naica Mine in Mexico. Scientists have also noted the extreme environment in which the microbes were discovered (the caves are so hot that explorers have to wear special insulated ice suits that permit them to stay in the caves for only minutes at a time). Moreover, after successfully extracting the microbes and culturing them, scientists discovered that they were genetically distinct from any other life on earth.

As the article points out, these microbes suggest once again that life on earth can exist in extreme conditions/environments and can remain dormant for long expanses of time. Think about the implications of that for the possibility of life elsewhere in the universe, and the likelihood that our own exploration could contaminate other worlds!

We know that there has been much speculation in the genre of science fiction (literary and film) over the years about how life on earth began. Did life on earth get its start from microbes that originated on other worlds? Did a meteorite or asteroid crash into this planet and seed life here? Did aliens either intentionally or unintentionally seed our planet with life in the distant past? Could our own exploration of the universe unintentionally seed other worlds with earth life? What would happen to these microbes if the earth exploded one day and hurled debris into space? If the microbes survived on a piece of debris or some man-made spacecraft, could they seed life on some distant planet or moon that provided an environment which was hospitable enough for its survival? Over millions and billions of years, would such life evolve into more complex forms (maybe even humanoids like us)?

And, finally, if the discovery of these microbes makes all of these scenarios seem a little less far-fetched, does that suggest anything about the purpose of life itself? If so, does that imply some design or designer? At any rate, I believe that the existence of these microbes on this little orb we call home gives us a few more things to think about and possibilities to consider. After all, why is life so tenacious? Does the impetus toward self-perpetuation suggest any answers to some of the most profound questions that we have? What do you think?

  1. Biology is too complex to arise spontaneously. Therefore I believe it was initiated by superior extra-dimensional being(s). The reason why we don't know.

  2. The zenith/apotheosis of evolution being modern man: an abandoned/stranded? experiment, subject to random intrinsic (war) and extrinsic (meteor) hazards.

  3. Are we the end product? Is it possible that we are only one of the links to something else? I agree that there's a lot we don't know.
