De-extincting Animals: A Wise Endeavor?
[guest post by Dana]
This is one of those things that makes me shudder. Do we really think that nothing will go wrong with this?:
The dire wolf once roamed an American range that extended as far south as Venezuela and as far north as Canada, but not a single one has been seen in over 10,000 years, when the species went extinct. Plenty of dire wolf remains have been discovered across the Americas, however, and that presented an opportunity for a company named Colossal Biosciences.
Relying on deft genetic engineering and ancient, preserved DNA, Colossal scientists deciphered the dire wolf genome, rewrote the genetic code of the common gray wolf to match it, and, using domestic dogs as surrogate mothers, brought Romulus, Remus, and their sister, 2-month-old Khaleesi, into the world during three separate births last fall and this winter—effectively for the first time de-extincting a line of beasts whose live gene pool long ago vanished.
The same company has now “copied mammoth DNA to create a woolly mouse, a chimeric critter with the long, golden coat and the accelerated fat metabolism of the mammoth”.
When presented with concerns about their endeavors, Colossal scientists explained that this knowledge could help endangered animals from going extinct, and that they could use the information about the woolly mouse to “engineer” elephants vigorous enough to survive the impacts of climate change. They also claim that what they learned in replicating the dire wolf can also be used to prevent certain wolves from extinction. Additionally:
“We are an evolutionary force at this point,” says Beth Shapiro, Colossal’s chief science officer, speaking of humanity as a whole. “We are deciding what the future of these species will be.”
And that is what makes me weary: a group of really intelligent scientists, armed with the power and ability to pick and choose what will happen to various species. Do we think that such knowledge will be used wisely and without an adverse outcome? After all, is there anything wrong with letting extinct animals remain just that?
