Microbe discovered in evolutionary stasis for millions of years
#science #biology #evolution #bacteria #pangaea
It's like something out of science fiction. Research has revealed that a group of microbes, which feed off chemical reactions triggered by radioactivity, have been at an evolutionary standstill for millions of years. The researchers stated that these microbes hardly changed since the breakup of supercontinent Pangaea, about 175 million years ago, and they appear to be living fossils from those days. It was hypothesized the standstill evolution is due to the microbe's powerful protections against mutation, which have essentially locked their genetic code. If the researchers are correct, this would be a rare feature with potentially valuable benefits in biotech applications, such as DNA sequencing, diagnostic tests, and gene therapy.
