According to recent research, the two-million-year-old has been found which has opened a new chapter in the history of evolution. It is said that this DNA was found in the ice age sediment in Greenland. With the help of technology, the researchers have identified DNA fragments that are even older than the previously found 1 million years DNA sample from the Siberian mammoth bone. And this old DNA has been used to create a new map of the evolution and ecosystem that changes due to extreme climatic change.
The change in DNA could help to predict the environmental change, and certain climatic changes of that time and now, the long-term changes of today’s global warming. After founding his 2-million-year-old DNA can help to know the past ecosystem a long way back in time. Now scientists and researchers can go into the past, further in time to know more about the old times and earth’s conditions.
The researcher also said that these ancient DNA samples were found deep in sediment that had been built over 20,000 years. The sediment was preserved in ice or permafrost (which means frozen ground for many years), and there was no interference from mankind for 2 million years.
These ancient DNA samples are a few millionths of a millimeter long and were taken from the Kobenhavn formation, a sediment deposit almost 100 meters thick that is tucked in the fjord in the Arctic Ocean in Greenland’s northernmost part. However, the climate of Greenland varied between the Arctic and temperature and was between 10-17 degrees Celsius warmer than that of today.
Even scientists have discovered some evidence of animals, plants, and some microorganisms like hares, poplar trees, and birch. Researchers even found that Mastodon, an Ice Age mammal, roamed in Greenland before extinct.
Researchers from 40 countries have worked on the ancient DNA, and after so much hard work, they could able to reveal the details. They need to be ensured that the hidden DNA was in the clay and quartz, and if there was, they could extract further details about it. After ensuring this, researchers compared the DNA fragments with the present-day animals, plants, and microorganisms of the DNA from trees, bushes, birds, and animals.
Even some DNA was easily classified as predecessors to the current species, and some originate from some species that are still living in the 21st century. However, the two-million-year-old samples also help academically to understand the previously unknown stage in the evolution of the DNA of a range of species still in existence today. Further research, they have revealed that with the help of advancements in technologies they were able to create a map of two-million-year-old ecosystems.
The research and data show that the Kap Kobenhavn ecosystem, that is no longer exists today, but at one time it was considerably higher temperatures than we have today and because of that the climate seems to have been similar to the climate we expect in our planet in the future due to global warming. Now global warming is rapidly increasing on the planet which means the organisms and species do not have longer that climate so the environment or climate emergency continues to be a huge threat to biodiversity and the world, now extinction is the uppermost for some species of plants, organisms, and trees.
It is just a hope that receiving the information of two-million-year-old DNA that was discovered may help to protect some endangered species and provide them with a relevant environment to protect and generate.
The research further said that DNA generally survives in cold, dry conditions such as those that are overcome during most of the period since the material was deposited at Kap Kobenhavn. Now scientists have extracted ancient DNA from clay and quartz, so it may be possible that clay may have preserved ancient DNA in warm, humid environments in sites found in Africa.
Conclusion– If the present world can extract information from million years old DNA, then we may be able to find the exact origin of species, the origin of life. the question would be always the same, what is the origin of life, that remains unexplained yet, but maybe one day the world will get the answer to how life on Earth was created, what is the origin of life, what is the origin of different species, there are lots of question and mysteries presented in nature and world are still finding the answers. Nature is a mystery, and to solve the mystery is our work.
Maybe one day the new chapter will begin about the first human or the first living organisms on Earth, there are lots of theories on it but without evidence. Hence the probabilities of these questions are infinite and continuous to find the answer.
