Group selection

Group selection is a proposed mechanism of evolution in which natural selection is imagined to act at the level of the group, instead of at the more conventional level of the individual. Early authors such as V. C. Wynne-Edwards and Konrad Lorenz argued that the behavior of animals could affect their survival and reproduction as […]

Mitochondrial Eve

Allan Charles Wilson (18 October 1934 – 21 July 1991) was a Professor of Biochemistry at the University of California, Berkeley, a pioneer in the use of molecular approaches to understand evolutionary change and reconstruct phylogenies, and a revolutionary contributor to the study of human evolution. He was one of the most controversial figures in […]

Tettigoniidae

Insects in the cricket family Tettigoniidae are commonly called katydids or bush crickets. More than 6,400 species are known. They are also known as long-horned grasshoppers, to distinguish them from the Caelifera, the true or short-horned grasshoppers. Part of the suborder Ensifera, it is the only family in the superfamily Tettigonioidea. Primarily nocturnal in habit, […]

the Myth of Race

Uploaded on Jan 31, 2008 One of the leading authorities on race and science, Troy Duster discusses how the understanding of race is being reshaped by the genomics revolution. Sometimes unintentionally and sometimes not so innocently, genomics may be generating a new and more sophisticated racism, not so different from the eugenics-based and criminological racism […]

Paleopathology

Paleopathology, also spelled palaeopathology, is the study of ancient diseases. Studying pathologies, these abnormalities in biologic individuals and systems, may be intrinsic to the system itself (examples: autoimmune disorders or traumatic arthritis) or caused by an extrinsic factor (examples: viruses or lead poisoning from pipes). Any living organism can have a pathology. Studies have historically […]

Proteomics

Proteomics is the large-scale study of proteins, particularly their structures and functions.[1][2] Proteins are vital parts of living organisms, as they are the main components of the physiological metabolic pathways of cells. The term proteomics was first coined in 1997[3] to make an analogy with genomics, the study of the genome. The word proteome is […]
