Scientists are working to bring extinct woolly mammoths and other animals back to life. A company called Colossal plans to bring woolly mammoths back to life using DNA technology by 2027. The company, which was established for this purpose, announced that it received an investment of 150 million dollars. Within the scope of the project, it is claimed that many creatures such as the extinct tasmanian tiger and dodo, as well as woolly mammoths, can be brought back to life. However, this project also causes controversy as it brings with it many ethical, scientific and technological problems.
Biologist George Church, who has been leading a research team at Harvard Medical School that has been working to reanimate woolly mammoths for eight years, said the project will make a difference in the world and will be an extremely important milestone. Colossal company, Dr. It will support research in Church’s lab and conduct experiments in its own labs in Boston and Dallas. Eriona Hysolli, Dr. While a former researcher in Church’s lab, he will oversee the work of editing elephant DNA at the new company. Within the scope of these studies, it is aimed to make the DNAs resistant to cold by adding genes with features such as dense hair and thick fat for mammoth characteristics.
The Question of Whether the Project Is Ethical
The researchers hope to produce embryos of mammoth-like elephants within a few years, eventually reinvigorating entire animal populations. However, some researchers were skeptical of Colossal’s project, “Is it humane to breed an animal whose biology we know so little about?” and “Who will decide whether this breeding animal has the potential to profoundly change the ecosystems of the tundra?” They raise questions such as: If the Colossal company is successful in producing baby mammoth-like elephants, it is likely to face serious ethical issues.
Beth Shapiro, a paleogeneticist from the University of California Santa Cruz and author of the book “How to Clone a Mammoth,” stated that this project brought with it many problems and there were tons of problems to be encountered throughout the process. She stated that in addition to the ethical dimensions of the project, many issues such as technical difficulties, costs and population management should be addressed.
Related Genes of Mammoths Will Be Rewritten
Colossal’s project was first introduced in 2013 by Dr. It was announced in a speech by Church to the National Geographic Society. During this period, researchers were learning how to reconstruct the genomes of extinct species based on DNA fragments from fossils. Then, by identifying genetic differences between ancient species and their modern cousins, they began to understand the implications of these differences in DNA.
Renowned for developing different DNA reading and editing methods, Dr. Church wondered if he could rewrite the genes of a living relative to revive an extinct species. Since Asian elephants and mammoths descended from a common ancestor about six million years ago, Dr. Church thought it might be possible to alter an elephant’s genome to produce a creature that looked and moved like a mammoth.
The Reason for the Revival of Mammoths
Dr. Beyond his scientific curiosity, Church thinks reanimated woolly mammoths could help the environment. Today, the tundra of Siberia and North America, where animals once grazed, is warming rapidly and releasing carbon dioxide. “Mammoths could hypothetically be a solution to this problem,” Church said. Today most of the tundra is covered with moss. But at the time of the woolly mammoths, the areas consisted largely of grassland. Some researchers argue that woolly mammoths were ecosystem engineers, able to protect grasslands by breaking down algae, knocking down trees and providing fertilizer with their excrement.
Russian ecologists hope to return the tundra to grassland by bringing bison and other species to a conservation area in Siberia called the Pleistocene Park. However, Dr. Church believes that reanimated woolly mammoths could do the job more effectively. It is thought that restored grassland could prevent soil erosion and erosion, and even retain heat-trapping carbon dioxide. Therefore, it is hoped that resurrected woolly mammoths will be ecosystem engineers to protect grasslands and make Siberia’s tundra productive again.
Possible Negativities and Criticisms
Dr. Although Church’s proposal received widespread media attention, it received limited funding from PayPal co-founder Peter Thiel. Dr. Church’s lab also focused on other, better-funded experiments. Dr. “This research can be used for many purposes, such as extermination or recoding of the human genome,” Hysolli said.
The scientists’ goal is to create an elephant embryo whose genome has been modified to resemble a mammoth. For this, they must first extract DNA from an elephant egg and replace this DNA with mammoth-like DNA. However, no one has yet managed to collect eggs from an elephant. Therefore, in case of failure, Dr. Hysolli and his team will investigate turning ordinary elephant tissue into stem cells and turning those cells into embryos in the lab.
Some philosophers, such as Heather Bushman, voice the moral concerns that may arise during the manipulation of living things. Such concerns include the potential suffering of animals, the disruption of the natural balance, and whether humans have a right to take control of nature. Dr. Shapiro states that such concerns need to be addressed and emphasizes that scientific ethical principles should be followed to minimize any risk of ethical issues while using technology. At the same time, he argues that technology should be used to avoid consequences such as the disappearance of the natural world and the extinction of species.
As a result, the use of technologies such as mammoth resuscitation can serve important purposes such as preventing species extinction and restoring the natural balance, although it raises many moral and ethical issues. Therefore, scientists need to work to preserve the natural world and provide a livable environment for future generations, while carefully considering the use of technology.
