Strange life forms
Strange life forms Did you know that .. extremophiles are primitive
forms of bacteria that have developed to live in harsh conditions,
like deep below the Earth's surface. Microbiologists now think that
extremephiles are our oldest ancestors, who thrived long before
oxygen was present in our atmosphere. nanobes are tiny creatures
smaller than any known bacterium. They are only 20 to 150
nanometres (billionths of a metre) long and are about the same size
as viruses. Nanobes were discovered 4 years ago by Australian
scientists digging 3 miles below the seabed. deinococcus
radiodurans is a super-strong bacterium that can withstand 3,000
more times radiation than a human being. They are commonly found in
cow and elephant dung and were first spotted in the 1950s when they
refused to die in food-sterilization tests. 5 APRIL 2000
