University of Maryland biologists have
0:09
identified a hidden sensory talent in
0:12
geckos that's shaking up what we thought
0:13
we knew about animal Hearing in a study
0:16
published in current biology on October
0:18
4th 2024 the researchers revealed that
0:22
geckos use the sakul a part of their
0:24
inner are traditionally associated with
0:26
maintaining balance and body positioning
0:29
to detect low frequency vibrations
0:31
according to the researchers this
0:33
special Sixth Sense also plays a
0:36
complimentary role to the gecko's normal
0:38
hearing and the way they sense the world
0:40
around them this previously unrecognized
0:43
hearing mechanism may be present in
0:45
other reptilian species as well
0:47
challenging existing ideas about how
0:50
animal sensory systems evolved and
0:52
diverged over time the ear as we know it
0:55
hears Airborne sound but this ancient
0:58
inner pathway which is typically link to
1:00
balance helps geckos detect vibrations
1:03
that travel through mediums like the
1:04
ground or water the sacul can detect
1:07
faint vibrations ranging from 50 and 200
1:10
Hertz a spectrum well below what geckos
1:13
can usually hear through their ears this
1:15
indicates that the SACU serves a
1:17
distinct yet complimentary function to
1:19
the gecko's regular auditory system
1:21
while geckos can hear Airborne sound
1:24
many other reptiles do not have that
1:26
ability the discovery of the Saul's role
1:28
in gecko hearing May lead to a better
1:31
understanding of communication and
1:32
behavior in other animals previously
1:34
considered to have limited auditory
1:36
capabilities a lot of snakes and lizards
1:39
were thought to be mute or deaf in the
1:42
sense that they do not vocalize sounds
1:44
or hear sounds well but it turns out
1:46
they could potentially be communicating
1:48
via vibrational signals using this
1:50
sensory pathway instead the existence of
1:53
this shared sensory pathway in modern
1:55
reptiles offers a unique window into the
1:58
evolutionary history of vertebrate
2:00
sensory systems suggesting that the
2:02
transition from aquatic to terrestrial
2:04
environments likely involved more
2:06
complex and gradual changes in hearing
2:09
mechanisms than previously thought think
2:11
about when you're at a live rock concert
2:14
it's so loud that you can feel your
2:15
whole head and body vibrate in the sound
2:17
field you can feel the music rather than
2:20
just hearing it that feeling suggests
2:22
that the human vestibular system may be
2:24
stimulated during those loud concerts
2:27
meaning our sense of hearing and balance
2:29
may also be linked closely the
2:31
researchers hope their findings will
2:33
prompt more investigations into Mamon
2:35
hearing especially in the context of the
2:38
sensory pathway they believe that the
2:40
established link between Hearing and
2:42
Balance opens new avenues for research
2:45
including the connection between human
2:47
Hearing and Balance disorders thanks for
