In 2003, scientists announced the 1997 discovery in an Ethiopian valley of three anatomically modern skulls-two adults and a child. Known collectively as the Herto skulls, they were dated by researchers to 154,000-160,000 B.P. All of the following clues suggested these skulls were in fact of anatomically modern humans, EXCEPT
A. evidence of the skulls' cutting and handling, suggesting they had been detached from their bodies and used-perhaps ritually-after death.
B. their long and broad midfaces.
C. their tall and narrow nasal bones.
D. their tall and narrow sagittal crests.
E. their high cranial vaults, falling within modern dimensions.
