On this day, 27 years ago, July 23, 1998 (June 1, 1998 in the lunar calendar), frozen sperm resurrected mammoths. Mammoth fossils Mammoth is a woolly elephant that lived in the Paleozoic era. Scientists estimate that between about 2.5 million and 30,000 years ago, this giant creature, with an average height of more than 4 meters, was common on all continents. Although they later disappeared completely from the earth for some reason, their bodies were preserved abnormally intact because some mammoths accidentally fell into ice holes while traveling and were covered and were in a frozen state. These large and well-preserved mammoth remains have provided modern humans with a lot of information about their structure and habits. According to written records, mammoths occupy a prominent position in primitive human art. British media recently disclosed that three scientists from the United Kingdom, Japan and Russia are trying to extract long-term frozen sperm from mammoths that died 40,000 years ago, and then use it to fertilize the egg cells of modern elephants, and finally resurrect the extinct mammoths after several generations of reproduction. Modern science and technology have proved that after several consecutive generations of cross-species mating, descendants with genes similar to ancestors can be obtained. It is reported that the test has been successful in cows. Scientists created surviving calves by injecting frozen sperm genes extracted from long-dead bulls directly into the egg cells of heifers. Interestingly, the three scientists come from three different fields. British geophysicist Smaley is one of the few underground radar experts in the world. His expertise is the use of radar for underground detection. His task was to find the exact location where the mammoth was buried underground. Japanese Goto is a university professor of veterinary medicine who is responsible for conducting various biological research on mammoths. Russian Razarev is an expert at the Yakutsk Mammoth Museum. He knows where to find the complete remains of mammoths. Smali said that an expedition team will go deep into the permafrost zone in northern Siberia near the Arctic, and members of the expedition team will take a boat along the Kolyma River to the most inaccessible place in the world. On both sides of the river are towering permafrost cliffs, and the glaciers on the cliffs have not been damaged for tens of thousands of years. The expedition team hopes to dig up a complete mammoth remains with blood, flesh and even hair here. In the summer of 1997, Smari and Wudou conducted a three-week preliminary inspection of northeastern Siberia to evaluate the feasibility of the entire plan. Smali said that during last summer expedition, they found many mammoth bone fragments and the remains of a complete horse buried in frozen soil for nearly 30,000 years, so there is reason to be confident in the expedition. The last time humans discovered the complete remains of mammoths was in 1977. At that time, gold miners from the former Soviet Union accidentally dug up the body of a baby mammoth that was only six months old while mining at a mine in Siberia. restored mammoth
