Article Title: Deepest Life on Earth May Be Lurking 6 Miles Beneath Ocean Floor
Summary: This article the results of some research which looked into rocks spewed out of undersea volcanoes. The rocks are estimated to have come from a depth of ten thousand meter below the sea floor. In the rocks the researchers found chemical makers of microbes, such a complex carbon compounds. While, no living microbes were found it could indicate that microbial life might extend to new unexpected depths in the Earth.
Connection: This article reminds me of the principle of ubiquity of microbes which states that microbes are found everywhere. Finding microbe that far under the surface of the earth defiantly supports that theory.
Critical Analysis: I found the article very interesting as I didn’t think that there was much life that far below the surface of the Earth. However, it is worth noting that this research didn’t prove that the organic traces were from bacteria as the Earth’s crust does move and thus I could see other ways that organic matter could have gotten to those depths. Also I am wondering how they kept their samples from getting contaminated.
Question: If there are microbes at depths of ten thousand meters, what do they use as and energy, and carbon source? What sort of lifestyle do they have?
