Neolithic technologies also spread eastward to the Indus River valley of India by 5000 BCE. Farming communities based on millet and rice appeared in the Huang He (Yellow River) valley of China and in Southeast Asia by about 3500 BCE. Neolithic modes of life were achieved independently in the New World. Corn (maize), beans, and squash were gradually domesticated in Mexico and Central America from 6500 BCE on, though sedentary village life did not commence there until much later, about 2000 BCE.
