...to rest spectacles on.

Hi everyone
I don't understand the underlined part in the text below:

"Thus the pinnae play an active role in sound localisation, suggesting that they did not evolve solely to rest spectacles on."

Thanks

It means that the pinnae evolved not only as something to attach glasses/spectacles to, but also to help in locating the direction from which sounds come from.

Thanks. I know it might sound awkward, but why would one attach glasses to the pinnae?

Not "attach." The arms of one's glasses rest on one's ears, in order not to fall off one's head.

They hook over my ears.

Oh thanks! now I understand.
