Given the fact that cloning is still a relatively new science, there are very few guidelines in place to ensure that this technology is utilized ethically. We cannot predict how the cloned individual will thrive, or how they would fit into modern human society. Extinct species have been absent for thousands or even millions of years, making it unlikely that their DNA could be found in a good enough condition to be cloned.Īnother significant challenge would be determining the ethical considerations of cloning an extinct species. In order to clone a species, scientists must be able to obtain DNA from within the nucleus of a cell, but the longer the DNA has been left to degrade, the more difficult this becomes. One of the primary challenges of cloning extinct humans is the vast amount of time that has passed since their extinction. However, the current state of our technology is still not advanced enough to effectively recreate an extinct human using cloning methods. In theory, cloning extinct humans could be possible if DNA belonging to an extinct human species, such as Neanderthals or Denisovans, was found intact and well-preserved. The prospect of cloning extinct humans is a contentious and ethically complex issue that raises a number of scientific, societal, and moral implications. Therefore, it is highly unlikely that dinosaurs will exist again in the same form they did millions of years ago. While it may be possible to create animals that have some aspects of dinosaur genetics or characteristics, the likelihood of recreating a complete, living dinosaur is currently low given our current level of technological and scientific advancements. Even for these species, the process is incredibly complex and has not yet been successful in producing a living organism. So far, these projects have been focused on smaller, more recently extinct species, such as the Pyrenean ibex and the passenger pigeon. There are, however, scientists working on “de-extinction” projects, which aim to bring back extinct species by using genetic engineering and advanced reproductive technologies. Moreover, the technology for creating viable dinosaur embryos and bringing them to term in a surrogate mother does not yet exist. Dinosaurs lived in a very different environment from modern organisms, and recreating their habitat and ecosystem would be incredibly difficult. However, the genetic material from dinosaurs is highly degraded and incomplete, making it impossible to recreate a complete genome.Įven if scientists could somehow extract a complete dinosaur genome, it would be a huge challenge to recreate a living dinosaur. Since then, their fossils have been discovered and studied extensively, and scientists have even extracted DNA from some dinosaur fossils. Will dinosaurs exist again?ĭinosaurs went extinct around 65 million years ago due to a catastrophic event, most likely a large asteroid impact that caused massive climate change and wiped out 75% of all living species. Instead, we can focus on preserving and protecting the remaining species on our planet to prevent further extinction and ecosystem collapse. Therefore, while the idea of cloning a dodo bird may seem intriguing, it is currently not possible with our current technologies and resources. Even if scientists could eventually overcome these obstacles and find a suitable surrogate, they would still need to overcome the ethical concerns related to playing god with nature and resurrecting an extinct species. There are no surviving species closely related to the dodo bird that could serve as a surrogate mother. In addition to this, cloning an extinct species would also require a surrogate mother of the same or similar species to carry the cloned embryo to term. There is no viable DNA source that can be used for cloning a dodo bird. Unfortunately, all known dodo bones and specimens have significantly degraded DNA due to their age and environmental conditions. While scientists have been successful in cloning certain animals, such as sheep and cattle, attempts to clone extinct species have been largely unsuccessful.Ĭloning a dodo bird would require DNA from a preserved dodo specimen. The dodo bird, which was once native to Mauritius Island in the Indian Ocean, has been extinct for hundreds of years.
