Let's dive into the really cool science
0:01
behind how we are actively re-wiring
0:03
man's best friend. Have you ever heard
0:05
of the 1950s Russian fox experiment?
0:07
Scientists bred silver foxes strictly
0:09
for friendliness, and within just a few
0:11
decades, these foxes didn't just act
0:13
tamer, their bodies physically changed.
0:16
They got floppy ears, spotted coats, and
0:18
wagging tails. Now, compare that rapid
0:20
change to our modern service dogs.
0:22
Organizations breeding dogs for
0:24
unflappable calmness in loud cities are
0:26
creating populations with distinct
0:27
biological markers. These calm dogs
0:30
actually show significantly higher
0:31
levels of oxytocin. That's the love and
0:33
bonding hormone, compared to your
0:35
average pet, and way more than wolves.
0:37
It's proof that we are successfully
0:38
mapping and selecting for the genetics
0:40
of calm in real-time. But, it's actually
0:43
even faster than selective breeding
0:45
across generations, thanks to something
