Fossil
of Australopithecus afarensis (known as Selam or LIttle
Lucy) suggests anatomical adaptations to walking on two legs while
also well adapted to living in trees. A unique tongue bone suggests
speech was unlikely.
"An interesting feature is
the hyoid or tongue bone, never found before in a species older than
Neanderthal man. It influences the voice box and is important to the
debate about the origins of human speech. Selam’s hyoid is much
more similar to that of modern apes than humans, suggesting that A.
afarensis was not capable of language." Read

Some authorities believe language emerged at this time, in parallel
with a surge in the creation of cultural artifacts. It is not likely
to have emerged later than this period.
