No, the terrible wolf did not return from extinction.

A company called Colossal Biosciences has resurrected a terrible wolf, an extinct species. “On October 1, 2024, for the first time in human history, the giant successfully restored a strong species through the science of Extinction. What we know is:

what’s the matter?

COLOSSAL claims that three genetically variant gray wolf puppies -two men named Remus and Romulus, born in October, and a woman named Khaleesi in January. The same company recently announced the creation of wool mice and almost complete thylacine or tasmanian tiger genome.

What is a serious wolf?

The terrible wolf is a big extinct fangs.Aenocyon dirus) It lived in America about 10,000 years ago. The animal looked like a big wolf with a white coat. They became famous by him Throne TV Series -So Khaleesi is the name of the show.

So, is a serious wolf species of an extinct wolf?

no. Gray wolves and terrible wolves were thought to be very closely related to physical similarity, but 2021 study of ancient DNA They said they shared their last ancestors about 6 million years ago. Jackals, African Wild Dogs and DHOLES are all more closely related to gray wolves.Canis lupus) Despite the similar appearance, the terrible wolf

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

Colossal’s Beth Shapiro says her team has sequenced the terrible wolf’s complete genome and will soon be released to the public. Shapiro could not say New scientist The two species share 99.5 %of DNA. The gray wolf genome has about 2.4 billion base pairs, so it still leaves a space for millions of basic differences.

And do you claim that you have changed the gray wolf into a terrible wolf through a huge gene editing?

That is the claim. In fact, five of these 20 changes are based on mutations that are known to produce light coats in gray wolves, SHAPIRO said. New scientist. Only 15 people are based on terrible wolf genome and to change the size, muscles and ears of animals. SHAPIRO said that this change would be about a year before it became clear whether this change had a intended effect on genetically modified animals.

So, is this puppy really afraid of wolves at all?

Shapiro says all of this depends on how to define species. “The concept of species is a human classification system, and everyone may agree and everyone can be right,” she says. “You can use systemic science [evolutionary relationships] The concept of a species is to decide to call the servant. This is what you suggest… We use the concept of morphological species, and if they look like this animal, they are animals. ”

What is the gene editing gray wolf that looks like a terrible wolf?

Shapiro says it is raised from 800 hectares and is being observed and cared for there. “They can’t get fragments unless we know,” she says. There are no plans to breed.
