It was thought that life could not exist in these harsh, dry, cold, environments but in the 70's rocks from Antarctica had complex microbial communities of lichens and cyanobacteria. Dr. Hand explains that studying microbes is tricky because if you bring the rocks up from the extreme environments they often change what they're doing.
