- n. An organism that lives and thrives in an extremely hot environment, such as a deep sea smoker vent; often a member of the Archaea.
The scientists propose, then, that crenarchaeal viruses have simply maintained their originally diverse morphologies, whereas viruses of non-hyperthermophile hosts (including other crenarchaeal viruses) have not.
Analysis of the "tree of life" derived from ribosomal RNA has led to the suggestion that the common ancestor of all life was a hyperthermophile (an organism adapted to very high temperatures)
Archaea is bacteria's most recent common ancestor - it was most likely hyperthermophile, an organism that thrived in extremely hot environments, approximately 2.5 - 3.2 billion years ago.
According to the judge’s logic, an isolated polymerase with extremely desirable and previously unexpected properties obtained from a previously uncharacterized hyperthermophile in the bottom of the ocean would also be unpatentable.
