New Words on the Origin of Speech

Believers in universal common ancestry long believed that since humans and apes diverged ages ago, apes should be able to talk as well as humans. Well, they have had enough time, but it did not happen. What about environment? Putting young chimps with humans was expected to give chimps speechifying ability.

Evolutionists have been telling stories about why apes cannot speak like humans. New research made things worse for them.

Since that failed, hands at the Darwin Ranch fired up the rescuing devices, and it was decided that a passel of storytelling was in order. It was figured that the larynx was lower in humans than in apes, so the Descended Larynx "theory" was conjured up (without any evidence supporting it). That supposedly made it possible for humans to make the necessary sounds that are heard in the world's languages.

"Does that mean apes didn't have vowel movements, Cowboy Bob?"

So anyway...

We have seen that there are many factors involved in communication, and critters are just not designed by the Master Engineer for complex communication and speech itself — especially understanding one another. Creationists know that such foolish speculations will fail because we were created separately from the animals. Newer research has Darwinists thinking that primates made some vowel sounds long ago, so the origin of speech was pushed back a few million years. Once again, get out the pen and ink well and commence to rewriting the evolution books again.
Speech is considered the cornerstone of the human species that separates us from all lower primates. Speech requires numerous essential articulators, including the teeth, tongue, jaw, lips, a descended larynx and several critical brain structures including Broca’s and Wernicke’s areas. No earthly creature has speech except humans, in spite of controversial efforts to train various primates to learn sign language as an effective means of communication.
