Automatic TRANSCRIPT

The only life there's microbial and researchers studied to get an idea of what we might find on Mars. According to geological evidence the desert core has been and semiarid or arid for fifteen million years and no rain had been recorded there for five hundred years but then something strange happened spend starting in two thousand fifteen it has rained several times in the Tacoma desert desert was a bloomed with life nats. What scientists thought might happen but it didn't actually the rain killed most microbial life in the region causing some species to go extinct hog be water is necessary? Florida water is necessary for life but over the eons the Atacama microbes evolved highly specialized strategies for optimizing. Is it the extraction of scarce humidity from their environment. They couldn't cope with the sudden influx of abundant water into their cell membranes and win. The rains came. They swelled and burst before the rain. Researchers estimated there were sixteen different species of microbes in the soil of the Atacama desert core. There are only two to four left able to survive in these transitory sources of water. All this might have implications for finding life on Mars ars more than three and a half billion years ago geological evidence shows water was abundant on Mars then became dry with occasional episodes of massive flooding. If Mars is like the Tacoma than those floods might not have helped Martian life to persist they might have killed it off. This moment of science comes from Indiana University on the world but
