Man’s Primeval Home and His Earliest Known Remains
If man is therefore essentially one, he cannot have had more than one primeval home. This human cradle, as it may be called, has been located with some certainty in the Eastern Archipelago, and more particularly in the island of Java, where in 1892 Dr. Eugene Dubois brought to light the earliest known remains that can be described as distinctly human. From the Pliocene (late Tertiary) beds of the Trinil district he recovered some teeth, a skull, and a thigh-bone of a being whom he named the Pithecanthropus erectus, thereby indicating an “Ape-man that could walk.”
In this “first man,” as he has been designated, the erect position, shown by the perfectly human thigh-bone, implies a perfectly prehensile (grasping) hand, with opposable thumb, the chief instrument of human progress, while the cranial capacity suggests vocal organs sufficiently developed for the first rude utterances of articulate speech.
