Barbarian chuckles:
These findings may explain why early studies, which were made in room illumination, usually failed to prove any major visual capacity in microchiropteran bats (e.g. Eisentraut 1950; Curtis 1952).
In other words, they don't have any major visual capacity. Simple English does the trick every time.
I don't think we're talking the same language, or you're copping out with this wriggle. Let me pin you to the floor.(Barbarian, regarding how bats learned to fly)
Probably the way birds do. Seems to work.
It took us a long time to get you to admit that birds have to learn to fly. Are you now denying that bats have to do that? Show us.
Existing birds learn to fly, since no egg can fly. Granted.
But that's not the problem we're addressing here. Please stick to the question.
HOW DID THE PROTO-BIRDS, who WEREN'T BIRDS, learn to fly, and so become full birds? Remember, their parents couldn't fly, and as you may not know, gliding isn't flying by a long way.
So to return to the bat, lest you slither away.
Proto-bat (can't fly) -----X----Y----Z----> Bat (can fly)
The question is, how did proto-bat and X,Y,Z learn to fly? See below for your diving technique exposure.
At least you'll be able to see as well as a bat, then...
As you've now been shown, that is NOT the question being asked. See above comments.Show us that it means they don't have to learn, as birds do.
Out of your own post will I condemn thee and thy theory.Onychonycteris finneryi. Transitional to modern microbats, that has claws on all fingers, short wings capable of fluttering or gliding, and long rear legs. Surprise.
Transitional: If O. is a bat, and the very first bat found, then it cannot be transitional. It IS a bat. Maybe an early (in time) bat, but definitely a bat with no antecedents.
So it could fly, and had echolocation capacities too. Nothing primitive about that!However, a study in 2010 has also uncovered evidence for other bone structures indicative of laryngeal echolocation, opposing the conclusions of the previous study by showing that Onychonycteris finneyi did possess the ability to echolocate after all.
Short wings: Why does it have wings? Because it could fly. Nothing transitional there.
One author:
[FONT="]: ‘These fossils represent essentially modern-looking microchiropterans; bats had evolved all of their characteristic features and begun to diversify by this time. In fact, the oldest known complete fossil bat, the Eocene-age Icaronycteris shown at left, shows specializations of the auditory region of the skull that suggest that this bat could echolocate.’[/FONT]
National Geographic:
Although the fossil record is notably lacking, scientists believe that bats fully capable of flight and echolocation, or locating prey and other objects through sound waves, emerged during the geologic time period known as the Eocene (about 50 million years ago), probably in North America....
How they emerged is neatly glossed over, in fact is not even mentioned! So you are being called upon to fill in that great blank spot! Might be a bit too much...
How true - and they completely wreck any theory of evolution."Bats are a spectacular group of mammals, with a combination of two remarkable specializations that you don't see in any other land mammals: flight and echolocation," Springer said.
You'll have to complain to Him. I'm just observing what it is.
No you're not. You're closing your eyes very firmly and shouting 'they evolved' when it's pretty obvious to anyone as blind as a bat that they didn't.
Now go on, admit that the theory leaks like a sieve in this matter. In fact there ISN'T a theory about this matter.
Genes making a bone longer? Do you think that if we took a piece of the metal they use in aeroplane wings and make it longer and longer and longer it'll turn into a wing?
No, because there are a lot of missing factors, like intelligent design, for starters.
(Someone is puzzled as to the origin of echolocation)
Modification of something already there. You have an echolocating ability, for example. People have used it to navigate near coastlines in heavy fog, by shouting and listening for echos. In a large empty building, you can actually use it to navigate.
You've cut out my nice little story. It makes the point supremely well, and leaves you in the dust.
How did a non-flying, non-echo-locating proto-bat ever become a flying, echolocating bat?
Why, by jumping off trees and cliffs while trying to catch insects, of course. How else?
Oh yeah, by waving their fingers in the air as they hurtled to the ground and destruction! The faster they fell, and the more frequently they fell, the faster they evolved! And their screams as they headed groundwards bounced back off the ground so they could measure the speed with which they would hit the ground! And that's how echolocation arose.
No wonder they are ultrasonic - they got more and more high pitched as the creature realised the end was rapidly approaching!
That's my scenario. What's yours?
Of course! See above! :biglolReality is a powerful argument.
Ah, you're arguing with yourself again. Let us know when you two are done.
Here:Unlikely. You seem to have no idea what the military has in that regard.
[FONT="]. In addition to the ability to navigate in complete darkness by echolocation, both bats and dolphins live in very social environments using echolocation in group situations without any obvious problems with interference. All of these capabilities are highly desired by current military programs developing unmanned-aerial vehicles (UAV) especially since many of the target environments are in places where Global Positioning System (GPS) signals are unavailable and obstacle locations are not mapped.

You were saying?
I've stated many times that nobody knows where instinct is located.If you think there is an "instinct gene", you must be homozygous for the gullibility gene.
Since instinct is obviously inheritable, because generation after generation does exactly the same things, then the genome seems the most likely location for transmission of an instinct.
If the genome is NOT the location, and I'm not saying it is, then we are in the realms of the spirit, and your evolutionary problems become even more horrendous.
