The earliest australopithecines very likely did not evolve until 5 million years ago or shortly thereafter (during the beginning of the Pliocene Epoch) in East Africa.
The australopithecines took advantage of these new conditions.The primate fossil record for this crucial transitional period leading to australopithecines is still scanty and somewhat confusing.However, by about 4.2 million years ago, unquestionable australopithecines were present.The concept of yin and yang became popular with the work of the Chinese school of Yinyang which studied philosophy and cosmology in the 3rd century BCE.The principal proponent of the theory was the cosmologist Zou Yan (or Tsou Yen) who believed that life went through five phases ( Yin is feminine, black, dark, north, water (transformation), passive, moon (weakness and the goddess Changxi), earth, cold, old, even numbers, valleys, poor, soft, and provides spirit to all things.
