"Homo habilis" emerged about 2.1 Mya. Its type locality is near those for "Homo habilis" and "Paranthropus boisei". OH 7 is now considered the type specimen of "Homo habilis". The genus emerged with the appearance of "Homo habilis", just over 2 million years ago. These important differences indicated a different species, which eventually was named "Homo habilis". It is a well-preserved jawbone assigned to "Homo habilis", dated to c. 2.4 Ma. "Homo habilis" came about two million years ago. The same process was used for OH 7, the holotype of "Homo habilis" (handy man). "Homo habilis" lived from about 2.8 to 1.4 Ma. Other finds including "Homo habilis" fossils were subsequently made. While "Homo habilis" was certainly bipedal, its long arms are indicative of an arboreal adaptation. Recovery of "Homo habilis" habitation has been made at these caves. Furthermore, "Homo habilis", living approximately 2.3 mya, is the most sexually dimorphic early hominid.
