No, the dire wolf has not been brought back from extinction

A company called Colossal Biosciencees says it has revived the extinct species – terrible wolf. “On October 1, 2024, for the first time in the history of mankind, Golossal succeeded in restoring a kind of species that was behaving once through the flag. This is the claim submitted on the US -based website. This is what we know.

What happened?

Golossal claims that three as a result of a genetically modified gray wolf – two males called Remos and Romulus were born in October, and a female named Khalisi born in January – is actually terrible wolves. The company itself also recently announced the creation of the woolen mice and the complete thylacine, or Tasmanian Tiger, Genome.

What is a terrible wolf?

So, the terrible wolf is a type of extinct wolf?

no. It was believed that the gray wolves and terrible wolves were closely related to the physical similarities, but Study 2021 of the old DNA acid She revealed that she had last participated in a joint ancestor about 6 million years ago. Both monuments and wild and African dogs are closely related to gray wolves (SLISIt is terrible wolves, despite its similar manifestations.

Does this mean that there are many genetic differences between gray wolves and terrible wolves?

Beth Shapiro from Colossal says her team has infiltrated the complete genome of the harsh wolf and will soon be released to the public. Shapiro could not know New world How many differences there, but the two types said they share 99.5 percent of their DNA. Since the gray wolf genome is about 2.4 billion base pairs, this still leaves room for millions of husbands from the differences.

And huge allegations that they have turned gray wolves into terrible wolves by making only 20 genetic modifications?

This is the claim. In fact, five of these twenty changes are based on mutations known to produce light coats in gray wolves, Shapiro said New world. Only 15 are based on the terrible wolf genome and aims to change the size of the animals, their muscles and the shape of the ear. Shapiro says that this will be a year or so before it is clear whether these changes had the intended effects on genetically modified animals.

So this puppies are not a terrible wolves at all, then?

Shapiro says that all of this is related to how species are determined. “The concepts of species are human classification systems, and everyone can differ and everyone can be right,” she says. “You can use Phylogenetic [evolutionary relationships] The concept of species to determine what you will call somewhat, which is what it contains … We use the concept of morphological species and say, if they look like this animal, they are the animal. “

What will happen to modified gray wolves that resemble terrible wolves?

Shapiro says they are raised in a reserve of 800 hectares where they are observed and carried out. “They cannot get a splinter without knowing us,” she says. There are no plans to allow them to multiply.
