Important lesson Jurassic park though us is ” LIFE ALWAYS FINDS A WAY “. However scientists decided to recreate that and ” bring back organisms from dead “.
ZOMBIES BACK TO LIFE:
Tiny zombies that were frozen in Arctic permafrost for 24,000 years were recently brought back to life by the scientists of Russia and they further produced clones for them in a laboratory. The undead organisms are called bdelloid rotifers, or microscopic “wheel animals” named for their circular mouths surrounded by tiny hairs. Rotifers are multi cellular organisms that can live in fresh waters and they have been around for about 50 million years. In these years they have learnt to adapt and survive. They can live in astonishing conditions like red-hot undersea vents or the vacuum of space. Later it was found that modern rotifers can be frozen at minus 4 degree Fahrenheit and then can be retrieved up to ten years later.
For this experiment, the scientists went to Siberia and carved off a slice of permafrost ( the term for ground that permanently stays frozen ). This particular area that the scientists carved off has been frozen since at least the end of the Pleistocene epoch ( that is about 2.6 million to 11,700 years ago ). The scientists took the rotifers and thawed them gently. ( thaw – to make something become soft or liquid again after freezing ). By doing so, at a particular point the rotifers came to life again which also included their characteristic sexual reproduction. They also began to reproduce asexually through parthenogenesis which leads to creating clones that were genetic duplicates.
Rotifers evolved to use cryptobiosis because most of the them live in watery habitats that freeze or dry up, Stas Malavin, a researcher and lead author told Live Science. “They suspend their metabolism and accumulate certain compounds like chaperone proteins that help them to recover from cryptobiosis when the conditions improve,” Stas Malavin stated.
By the way, this is not the first time ancient life has been resurrected.
