The earliest and longest part of the Paleolithic stage of development. The Lower Paleolithic began with the Oldowan tool tradition of Homo habilis and continued with the Acheulian tradition of Homo erectus and early archaic humans. The Lower Paleolithic began about 2. 5-2. 4 million years ago and continued until after 100,000 years ago. Lower Paleolithic tool making was the height of technology for most of the time that we have been human.

The disease of babies and very young children resulting from long-term severe protein deficiency in the diet. There is usually an associated deficiency in the consumption of vitamin A and E as well as zinc and selenium. Symptoms include edema (or swelling) due to water retention (especially in the abdomen), stick-like legs and arms with little fat or muscle mass, apathy, and loss of hair and skin pigmentation in patches. As in the case of marasmus, children with kwashiorkor are likely to have their growth retarded. Kwashiorkor usually results from a child being weaned too early and being forced to subsist mainly on a high carbohydrate and low protein diet.

Industry:Anthropology
The development of a similar anatomical feature in distinct species lines after divergence from a common ancestor that did not have the initial trait that led to it. The common ancestor is usually more distant in time than is the case with parallelism. Convergence is thought to be due primarily to the independent species lines experiencing the same kinds of natural selection pressures. Convergence is also referred to as convergent evolution. Convergence results in homoplasies.
