A new study has [revealed / revelation] that a tiny, water-dwelling creature is [likely / lively] to live until the end of the Earth. The [nears / near] indestructible tardigrade, also known as water bear, looks like a short caterpillar with eight legs. It is just one-tenth of a millimeter [in / on] size but has the physiological makeup to be [capability / able] to survive in any extreme conditions. The [microscopic / microscope] water bear can survive without food for three [decadence / decades] . It can also [exist / existence] in bitterly freezing temperatures of -272º Celsius and in furnace-like temperatures of 150ºC. Water bears can also survive the crushing pressure of deep oceans, the [vacuum / hoover] of outer space, nuclear war, global warming, or any other extreme meteorological event that would [gloom / doom] humans.

Scientists say water bears are so [hardy / hardly] and resilient that the only thing that would wipe them out for [bad / good] is if the Sun boils all the Earth's oceans away. The study says this is [likely / liking] to happen in several billion years [from / for] now. The new study states that complex life is extremely difficult to [destroy / destruction] and could exist on other planets. A researcher said: "Tardigrades are as [close / closely] to indestructible [as / has] it gets on Earth, but it is possible that there are other resilient species examples [elsewhere / or else] in the Universe." He added: "There is a real [carton / case] for looking for life on Mars and [on / in] other areas of the Solar System. If tardigrades are Earth's most resilient species, who knows what else is out there?"
