Our earliest relatives in California

Abstract

In the tropical jungles of the Philippines, Celebes, Sumatra and Borneo lives a shy, curious, goggle-eyed little creature, no bigger than a small squirrel. He looks somewhat like a monkey, with large bare ears, long tail and a coat of soft brown fur. On the under surfaces of his fingers and toes he has round sucker-like disks by which he fastens himself to the trunks and branches of his arboreal world. Certain bones in his feet are elongated, which allows him to jump nimbly from branch to branch and from tree to tree.
