Science continues to surprise us with impressive advances with stem cells. This time, a team of researchers is at the forefront of a project that could change our perception of the past.
Following in the footsteps of the American company Colossal, these scientists have embarked on the challenge of reviving woolly mammoths, a species extinct for thousands of years.

How can you revive mammoths according to science?
According to an article in El Confidencial, Colossal has been working on the development of genetic editing technologies that allow these majestic creatures to be recreated. About a year ago, they announced their ambitious goal of resurrecting mammoths by 2027.
However, recent statements from the company suggest that they could be much closer than initially thought.
They claim to have completed a crucial step in this process: the conversion of normal elephant cells into pluripotent stem cells. These cells have the potential to transform into any type of cell needed to rebuild the mammoths’ bodies.

This advance represents a significant milestone on the path to the resurrection of mammoths, as it provides the cellular basis necessary to rebuild their tissues and organs.
In an unprecedented achievement, Colossal researchers have managed to create pluripotent stem cells from elephant skin cells, marking a major milestone in their quest to resurrect these prehistoric creatures.
The founder of Colossal, George Church, highlights that the goal is not simply to restore a perfect mammoth genome, but to introduce modifications that provide these animals with beneficial characteristics, such as resistance to herpesvirus, a threat that affects elephant calves.
Furthermore, the plan goes beyond creating a single individual, seeking to establish entire herds of mammoths, socialized and adapted to their natural environment.
The research not only aims to demonstrate the viability of this technology and reverse the extinction of species, but also to reintroduce the woolly mammoth to its original habitat as a strategy to combat climate change.
Although it sounds ambitious, they argue that the migratory patterns and feeding habits of these giants could have a positive impact on the preservation of the Arctic and, therefore, the entire planet.

Is the resurrection of extinct species viable?
As technology advances and the boundaries of the possible expand, important questions arise about the ethics and viability of projects like Colossal.
It is key to reflect on the challenges and implications of reviving extinct species. Some points to consider are:
-
environmental ethics: What are the environmental consequences of reintroducing extinct species into ecosystems that have changed significantly since their disappearance? Could these species alter the natural balance and threaten existing species?
-
Community participation: Are the opinions and concerns of local communities that could be affected by the reintroduction of extinct species being taken into account? Are sufficient efforts being made to involve society in the debate about these projects?
-
Long term sustainability: What guarantees are there that the reintroduction of mammoths and other extinct species will be sustainable in the long term? Are monitoring and management measures being considered to ensure that these populations can thrive without causing harm to the environment?
