AL 666-1 (The fossil record of Homo sapiens)

The jaw structure of fossil AL 666-1 was quite different from that of A. afarensis and the 1.75-million-year-old H. habilis fossil with which it was found.  The jawbones of these two species are narrow and quadrangular, similar to those of modern-day apes.  But the fossil AL 666-1 has a jaw structure similar to that of modern human beings.

In spite of the fact that fossil AL 666-1 has been determined to belong to the Homo (human) genus, evolutionists hesitate to interpret it as such. This is because the age of this fossil is calculated at 2.3 million years, much earlier than the age accepted for the Homo genus as a whole.
