#deExtinction: "The American company #Colossal changed only 14 genes to produce its cute "#direwolf" puppies. Curiously, all 14 are genes with effects on the appearance of animals, being linked to the colour, thickness and length of the fur and the size of the animals.

Is #resurrecting a species now just #cosplaying an extinct animal with a current species? To top it off, George R.R. Martin himself - yes, the author of #GameofThrones - signs the scientific article as well. And he is an investor in the company. He compared the feat to a form of "magic". Only if it's to magically fatten his bank account even more."

Continued thread

it was my impression that thick white fur was more prevalent in arctic wolves, as it is obviously advantageous in such an environment. dire wolves lived in a temperate, or even rather warm region, so pale fur would certainly not be my first thought when it came to the coat colouration of dire wolves, anyone else find this suspect, especially since colossal evidently worked pretty hard to make them this colour?

my thing on the #colossal #direwolves WHAT DOES THIS MEAN FOR #PALEOART? obviously until that dire wolf genome is released to the public (something colossal said they would do) and is analyzed by proper scientists, and assuming what they find matches with what colossal has said (which certainly isn't a guarantee) should dire wolves be depicted in a way similar to the colossal specimens- mostly the thick white fur (more on that)

"#Direwolves dominated southern Canada and the United States, according to Julie Meachen, a paleontologist at Des Moines University who worked on the #ancientDNA project. And they outcompeted gray wolves, being 25 percent bigger and possessing massive teeth and jaws. They hunted horses, bison and possibly mammoths. When many of those prey species became extinct — probably in part because of human hunters — the dire wolf may have been doomed, and the gray wolf swept down from northern Canada and Alaska to fill the ecological void."

The New York Times · Scientists Revive the Dire Wolf, or Something CloseBy Carl Zimmer

"The question is whether Colossal’s leaders and supporters are willing to pivot from a project that grabs news headlines to ones that would likely make positive differences. By tempting us with the resurrection of a long-dead creature, #Colossal forces us to ask: do we want conservation to be primarily about feeding an unreflective imagination? Or do we want evidence, logic, and ethics to be central to our relationships with other #species? For anyone who really cares about the #climate, #elephants, or #animals in general, #deextincting the #mammoth represents a huge waste and a colossal mistake."

Ars Technica · Editorial: Mammoth de-extinction is bad conservationBy Ars Contributors

De-#extinction company provides a progress report on #thylacine efforts
Stem cell editing, complete #genome, and cane toad resistance mark necessary steps.
#Colossal released a progress report on resurrecting the thylacine, also known as Tasmanian tiger, which went #extinct in 1936. Marsupial biology has some features that may make de-extinction somewhat easier, but we have far less sophisticated ways of manipulating it compared to working with placental mammals.

Ars Technica · Effort to bring back the Tasmanian tiger builds steamBy John Timmer

De-#extinction company that plans to bring back the #mammoth takes a key step:Making #elephant #stemcells
#Colossal is forging ahead and cleared one of the many hurdles it faces: It created the first induced stem cells from elephants and will be placing a draft manuscript describing the process on a public repository on Wednesday. Beyond providing the technical details of how the process works, the manuscript describes a long, failure-ridden route to eventual success.
