Stress migration is a failure mechanism that often occurs in integrated circuit metallization (aluminum, copper). Voids form as result of vacancy migration driven by the hydrostatic stress gradient. Large voids may lead to open circuit or unacceptable resistance increase that impedes the IC performance.
Putative migration waves out of Africa and back migrations into the continent, as well as the locations of major ancient human remains and archeological sites (López et al., 2015). The population brought to South Asia by coastal migration appears to have remained there for some time, during roughly 60,000 to 50,000 years ago, before spreading ...
Molecular anthropology, also known as genetic anthropology, is the study of how molecular biology has contributed to the understanding of human evolution. [1] This field of anthropology examines evolutionary links between ancient and modern human populations, as well as between contemporary species.
The March of Progress, [1] [2] [3] originally titled The Road to Homo Sapiens, is an illustration that presents 25 million years of human evolution. It was created for the Early Man volume of the Life Nature Library , published in 1965, and drawn by the artist Rudolph Zallinger .

A developmental model of the evolution of the mind, culture, and society was the result, paralleling the evolution of the human species: [23] "Modern savages [sic] became, in effect, living fossils left behind by the march of progress, relics of the Paleolithic still lingering on into the present."
The delineation of the "human" genus, Homo, from Australopithecus is somewhat contentious, for which reason the superordinate term "hominin" is often used to include both. "Hominin" technically includes chimpanzees as well as pre-human species as old as 10 million years old (the separation of Homininae into Hominini and Gorillini).
The timeline of human evolution outlines the major events in the evolutionary lineage of the modern human species, Homo sapiens, throughout the history of life, beginning some 4 billion years ago down to recent evolution within H. sapiens during and since the Last Glacial Period.
