Our ancestors heard the world differently

Scientists have determined that early humans had very different hearing abilities than we do today.
The research was based on the careful reconstruction of the internal ear anatomy of two early humans using a combination of CT scanning and 3D computer modeling.

The findings indicated that our ancestors living in South Africa around two million years ago were much more sensitive to close-range sounds and could hear much softer sounds than we can today.

It is believed that this difference would have helped to facilitate close-range communication - something that at the time would have consisted of a series of vowel-based calls.

"We concluded that Australopithecus africanus and Paranthropus robustus had a heightened sensitivity to sound between 1.0-3.0 kHz compared with both chimpanzees and humans," said anthropologist Rolf Quam who led the study.
The discovery offers a unique glimpse back in time and helps scientists to understand how our ancestors' perceptions of the world changed over the last few million years.

But what will happen in the future - will our hearing continue to evolve ?

"It is unlikely that our hearing pattern will change much in the future," said Quam.

"Our previous studies have shown that human fossils that date to around 430,000 years ago from northern Spain, and which represent ancestors of the later-in-time Neanderthals, had a hearing pattern almost identical to our own."

I'm sure back then it was a much quieter world then it is now. So much more noise out there. And cell phones right to our ears make it so we don't need to hear things farther away from us. I could see that evolution.

So when they heard Thou Shalt Not steal they actually did hear Thou Shalt Not Steal and not Steal Only If You Can Get Away With It And If You Can Justify It To Yourself.

Perhaps you are right Athena1979 I can hear a pin drop 10 miles away if there is no background noise..
