Why de-extinction researchers are so enthusiastic about this skinned skull that has been preserved in ethanol for over a century
More than 99.9% of thew species' genome has been completed, according to scientists,thank to "ancient DNA" that was taken from the cranium. This is what that implies . . .
an expert on Australian mammals and assistant director of the Museum of Zoology
at the University of Cambridge. "For one reason, ecological integrity would greatly benefit from the presence
of a large predator."
However, there are buts. Since the thylacine, a wolf-sized and shaped carnivorous marsupial, went extinct decades ago,
how has Tasmania changed? How would people, particularly farmers, respond?
And perhaps most importantly, is it truly feasible to bring it back from extinction?
Colossal, a biosciences business, is growing more optimistic about its chances
of generating a thylacine. The company recently declared that it has completed over 99.9 percent of the species' DNA
and that complete completion should now be achievable, thanks to a skinned head preserved
in ethanol that has been in the possession of Museums Victoria for more than a century.
Beth Shapiro, chief science officer at Colossal, adds, "It is uncommon to have a sample
that allows you to push the limit in ancient DNA technologies to such a degree."
"Our thylacine de-extinction project will proceed more quickly thanks to the
record-breaking ancient genome we gave."

However, without any females to cultivate an embryo in, how can the thylacine be brought back? The fat-tailed dunnart is the answer. Despite appearing to be much different from a thylacine and resembling a mouse on the surface,
However, without any females to cultivate an embryo in, how can the thylacine be brought back? The fat-tailed dunnart is the answer. Despite appearing to be much different from a thylacine and resembling a mouse on the surface,
the fat-tailed dunnart is one of its closest surviving cousins. Both are members of the Dasyuridae family, which is made up of primarily small,
insectivorous marsupials, including quolls and Tasmanian devils.
Colossal intends to modify the dunnart's genome to resemble that of the thylacine as much as
possible, then implant this into an egg cell and develop the embryo in that manner. According to scientists, the emerging animal will resemble a thylacine but not be one.
Ashby is worried about the potential effects of any thylacine recreation on vulnerable
and living species, including the devil, which has been severely impacted by an infectious
cancer in recent decades, as well as how technically feasible this will be.
"Is owning an animal that resembles a thylacine preferable than having nothing at all?" "What?" Ashby asks. It is difficult to dispute that it would be; it is a fascinating moral dilemma. However, Colossal is making great strides in the field of marsupial conservation genetics,
and their w astrophe. ork may yield important data that may aid in addressing
Australia's marsupial extinction catastrophe.
