Gene linked to human speech - mice with the gene changed vocalizations

Not sure if this creepy or not ;)

A new study suggests the beginnings of
human speech are linked to genetics. The
research identifies a protein – found
only in people – that may have helped
early humans develop spoken communication.
Scientists involved in the study say this
new speaking ability became important for
humans’ survival. For example, speech
permitted individuals to share information,
organize activities and pass down knowledge.
These abilities are now seen as an advantage
humans had over their relatives, such as the
Neanderthals and Denisovans.

The aim was to test the real-life effects of
the genetic variant. The researchers were
surprised to learn that the variant changed
the way the animals called out to each other.
Baby mice with the human variant made a
different sound than normal mice do when
their mother came around. Adult male mice
with the variant also made different sounds
when they were near a female they wanted to
mate with.
