say hello to Romulus and Remis they're
0:03
not technically direwolves but a
0:05
Dallas-based biotech company says the
0:07
cubs are the closest thing to the
0:09
extinct creature that hasn't held in
0:11
more than 10,000 years colossal
0:13
Biosciences claims it produced three
0:16
direwolves by modifying the DNA of
0:18
modern grey wolf using the genome it
0:20
uncovered in a direwolf tooth and
0:23
fossils dating back 72,000 years they're
0:26
genetically really similar
0:28
99.5% similar and phenotypically their
0:32
their morphology is also similar only
0:34
direwolves are larger more muscular but
0:37
the company hasn't shared evidence to
0:38
back up its breakthrough leaving some
0:41
scientists skeptical when you claim all
0:43
these great big things and then you
0:44
don't provide the associated evidence
0:46
especially in something as controversial
0:47
as this that is a massive red flag if
0:50
Colossal's claim is true global ecology
0:53
professor Corey Bradshaw says it's best
0:55
to take these findings with a grain of
0:57
salt we don't have the technology to
0:59
modify entire genomes we can modify po
1:02
components of genomes and we can
1:04
certainly sequence genomes that's not
1:07
enough to create an entire genome and
1:09
these genetically engineered cubs lack
1:12
the instincts of naturalborn wolves
1:14
making them unlikely to answer the call
