Gene Involved In Human Language Development Also Involved In Bat Echolocation |
Sometimes when I'm stumbling around in a darkened room, I wish we had
evolved echolocation too.

Gene Involved In Human Language Development Also Involved In Bat
Echolocation
Science Daily ‹ When it comes to the FOXP2 gene, humans have had most to
shout about. Discoveries that mutations in this gene lead to speech
defects and that the gene underwent changes around the time language
evolved both implicate FOXP2 in the evolution of human language.
More recently, patterns of gene expression in birds, humans and rodents
have suggested a wider role in the production of vocalisations. Yet
numerous reports have established that FOXP2 shows very little genetic
variation across even distantly related vertebrates - from reptiles to
mammals -- providing few extra clues as to the gene's role.
A new study, undertaken by a joint of team of British and Chinese
scientists, has found that this gene shows unparalleled variation in
echolocating bats. The results, appearing in a study published in the
online, open-access journal PLoS ONE on September 19, report that FOXP2
sequence differences among bat lineages correspond well to contrasting
forms of echolocation.
Like speech, bat echolocation involves producing complex vocal signals
via sophisticated coordination of the mouth and face. The involvement of
FOXP2 in the evolution of echolocation adds weighty support to the
theory that FOXP2 functions in the sensory-motor coordination of
vocalisations.

goes.

I'm curious too. I recall some creationists once making fun of Dawkin's
discussion of bat echolocation evolution in one of the early chapters of
"Blind Watchmaker". It looks like the laugh's on them.

I heard they can sense objects, but is it by echolocation? I don't know
that they emit ultrasonic beeps.

Probably the senses of touch and hearing become more
sensative through extra use. Maybe the sense of smell.
But, that's probably it. I'd think that that would be a
natural development.

I posted two articles above in response to Michael that claim some blind
people can sense objects by echolocation. Maybe next time I'm in the

find the light switch.

Just ask a blind person.
I heard they can sense objects, but is it by echolocation? I don't know
that they emit ultrasonic beeps.
Probably the senses of touch and hearing become more
sensative through extra use. Maybe the sense of smell.
But, that's probably it. I'd think that that would be a
natural development.
peepbeepbeep<< CRASH! oops! Nope, doesn't
work when you're just nearsighted. Tripping over
three perfectly aligned cats doesn't help, either.
The idea that blind folk somehow 'sharpened' their others sense was,
for decades, poo-pooed by scientists.
But recent brain imaging has shown that their vision centres have been
'taken over' or recruited by their audio and tactile functions.
(As is the hearing bit of the brain in patients who have been deaf
from birth, a reason why cochlear implants are sometimes reviled by a
proportion of those who recieve them.)
Ain't the brain wunnerfull?
Something that 'duke' will never know.

Nope, some do it by the noise of their footfalls and the shuffle of
their clothing, as well as their breathing, and others can actually
make a brief whistle or vocal noise as an audible sort of echo
location.
I'm not joking.
You too, can do it with practise, assuming that you have reasonably
good hearing in both ears.

http://abcnews.go.com/Primetime/story?id=2283048&page=1
So it appears possible, but unlike bats it doesn't involve ultrasonic
emissions so as mentioned in the articles, it may not be as sensitive.

It is just as sensitive, but without the spatial resolution, a little
like the infra-red "heat pictures" that you see, that cannot resolve
the details that ultra-violet can.
"Muddier", in audio engineering terms.
Longer wavelength = lower resolution, you see.

You too, can do it with practise, assuming that you have
reasonably
good hearing in both ears.
I did find these:
http://en.wikipedia.org/wiki/Human_echolocation
http://abcnews.go.com/Primetime/story?id=2283048&page=1
So it appears possible, but unlike bats it doesn't involve
ultrasonic
emissions so as mentioned in the articles, it may not be as
sensitive.
It is just as sensitive, but without the spatial resolution, a
little
like the infra-red "heat pictures" that you see, that cannot resolve
the details that ultra-violet can.
"Muddier", in audio engineering terms.
Longer wavelength = lower resolution, you see.
That's what the articles implied. I gather you don't need high
resolution to avoid walking into walls, but you do to catch a bug in
mid
flight no less.
Not a popular pass-time amongst the sight-impaired, I am led to
understand.

Maybe he was a big bat in disguise? The original Batman?
Blind as a bat, and his robes stunk of guano, so you may have
something there, cricket.
Where's Robin?
Busy trying to work out why he has his underpants on the outside of
his trousers.
He was with the priest and the bishop unexpectedly stopped by so he had
to get dressed in a hurry.
