The mass number of one atom of an isotope (e.g., carbon-14). It is the sum of the number of protons and neutrons in the nucleus of one atom. See atomic number.

The male sex spores of flowering plants. Pollen particles are usually nearly invisible, except in large concentrations, due to their extremely small size. They can survive for hundreds of thousands of years in silty, anaerobic soils, such as mud sediments at the bottom of a lake. When excavated from early human sites, they can be used to reconstruct what the climate was like at the time of the occupations as well as relatively date them.
Industry:Anthropology
The maintenance of two or more alleles for a trait in a population at a more or less constant frequency ratio due to the selective advantage of heterozygotes. See polymorphism.

The Linnaean classification system use of two Latin name categories, genus and species, to designate each type of organism. A genus is a higher level category that includes one or more species under it. For example, humans are Homo sapiens, or "man who is wise"--Homo is our genus and sapiens is our species. Binomen or binomial nomenclature literally means "two names" in Latin.

The late 18th century theory of James Hutton that the natural forces now changing the shape of the Earth's surface have been operating in the past much in the same way. The most important implication is that the Earth is very old and that the present is the key to understanding the past. Elaborated on by Charles Lyell in the 19th century, this theory opposed catastrophism.

The last part of the Paleolithic stage of development in which Cro-Magnon and other late ice age modern Homo sapiens developed a number of sophisticated stone tool making traditions including the Magdalenian. This was the height of technical sophistication during the Old Stone Age. The Upper Paleolithic in Europe began about 40,000 years ago and ended around 10,000 years ago. Technological developments leading to the Upper Paleolithic may have begun somewhat earlier in Africa.
