You ask several questions. It is very difficult to obtain hard data on the
development of speech, because it involved changes in soft tissue rather
than bone. Soft tissue rarely survives in the fossil record. That is why
it is so difficult to say exactly when speech developed. The theory that
speech was associated with the cultural flowering circa 60,000 years ago is
only one. Others believe it began much earlier, when Homo sapiens sapiens
first appeared circa 100,000 years ago, possibly in Southwest Asia ("Middle
East) as you say. Also, remember, humans did not evolve from
monkeys. Monkeys and humans had a common ancestor. Big difference. You
also are right that only humans can express themselves in speech, because
of both brain and vocal cord differences (soft tissue).
