Chapter 13 Homo sapiens and the evolution of modern Human Behavior Upper Paleolithic-The period from about 45 kya to about 10 kya in Europe, North Africa, and parts of Asia. The tool kits from this period are dominated by blades. Blade-A stone tool, made from a flake, that is at least twice as long as it is wide. Blades dominate the tool traditions of the Upper Paleolithic. Mode 4-A category of stone tools in which blades are common. Mode 4 tools are found in some Middle Stone Age industries in Africa, and they predominate in the Upper Paleolithic industries of Europe. Mitochondrial DNA-(mtDNA) DNA in the mitochondria that is particularly useful for evolutionary analyses, for two reasons: (1) mitochondria are inherited only from the mother, and thus there is no recombination, and (2) mtDNA accumulates mutations at relatively high rates, thus serving as a more accurate molecular clock for recent changes (last few million years). Mitochondrion-(mitochondria, pl.) A cellular organelle that is involved in basic energy processing. Chatelperronian-(mitochondria, pl.) A cellular organelle that is involved in basic energy processing. Middle Stone Age-The stone tool industries of subSaharan Africa and southern and eastern Asia that existed 250 to 40 kya. The MSA is the counterpart of the Middle Later Stone Age-The tool industries found in Africa that correspond in age and type to the Upper Paleolithic industries in Europe. Mode 5-A category of stone tools in which microliths are common. The African Later Stone Age industries are typified by Mode 5 tools.
