Yet a recent study suggests that the echolocation subunits were mainly located in the central nervous system, while the subunits in the vocal apparatus were already present and capable of use before echolocation even evolved.

Because chimpanzees lack the vocal apparatus to make a variety of modulated sounds, the animals were taught a vocabulary of hand signs _ an approach first suggested in the 18th century by the French physician Julien Offray de La Mettrie.

Amongst the various objects on the ground floor there is a large head that shows the vocal apparatus, on which the visitor can, by pressing chosen phonetic characters, listen to the corresponding sound and see the physical place of articulation lit up.

:: : I imagine that we should be nearing the point where we can accurately model a human vocal apparatus and all the relevant musical instruments and their position in a room, and have a computer optimize the model to match the recording.

"' The spa specializes in treatment of the upper respiratory tract disorders, "'including chronic nose and throat inflammations, diseases of the vocal apparatus, allergies of the upper respiratory tract, bronchial asthma; musculoskeletal disorders, i . e . degenerative disorders of the spine and joints as well as rheumatoid disorders and rheumatoid arthritis.

This study supports the hypothesis of independent evolution of echolocation in " Aerodramus " and " Collocalia ", with the subsequent evolution of complex behaviour needed to complement the physical echolocation system, or just possibly that the vocal apparatus-parts of the echolocation system might even be inherited from some prehistoric nocturnal ancestor.

Recent in-depth analyses of the songs sung by birds and humpback whales show that, even when their vocal apparatus would allow them to do otherwise, the animals converge on the same acoustic and aesthetic choices and abide by the same laws of song composition as those preferred by human musicians, and human ears, everywhere.

This study supports the second hypothesis of independent evolution of echolocation in " Aerodramus " and " Collocalia ", with the subsequent evolution of complex behavior needed to complement the physical echolocation system, or even the third approach, as the vocal apparatus-parts of the echolocation system might even be inherited from some prehistoric nocturnal ancestor.

Utterly peaceful, moralistic, and highly intelligent ( Nebogipfel learns English in a matter of days and is soon able to speak it fluently-with some limitations due to the Morlocks'peculiar vocal apparatus, quite different from those of humans ), the only resemblance these new Morlocks have to the monstrous cannibals of the first future is that of appearance and dwelling " underground ".

My guess is that the teacher is asking, " An injury to what part of the vocal apparatus would produce speech that would sound like drunken slurring to most people . " The answer is a stroke or an injury to the brain would be the best mimic, because most of us can readily tell the difference between defects of central speech processing and defects of articulation.
