Broca's region.
Making an impression: Broca's Area
It was initially believed that the Turkana Boy, and members of his species, Homo ergaster, were capable of language. This was because the inside of the boys fossilised skull showed an impression from a part of the brain known as Brocas Area. Possession of Brocas Area was once considered to indicate the ability to speak.
New technologies such as Positron Emission Tomography (PET) have now caused this idea to be revised. PET scans highlight areas of the brain that are active during language activities. They have shown that Brocas Area does not always function during speech and cannot be used as evidence of speech in our ancestors.
How do we know if they could speak? - Australian Museum
Sorry USincognito, once again, what was..now isn't. Don't you ever get tired of these silly straw grabs going up in smoke?
