The area is historically known as Clare Market. The LSE has more than 10,000 students and 3,300 staff, just under half of whom come from outside the UK. It had a consolidated income of £340.7 million in 2015 / 16, of which £30.3 million was from research grants. One hundred and fifty five nationalities are represented amongst LSE's student body and the school has the highest percentage of international students (70%) of all British universities. Despite its name, the school is organised into 25 academic departments and institutes which conduct teaching and research across a range of legal studies and social sciences.

Document 5: Natalia Rybczynski: She is a research scientist with the Canadian Museum of Nature and holds a professorship at Carleton University in Ottawa, Ontario. Her doctorate was obtained at Duke University and her main interests are evolutionary functional morphology, particularly at the polar climes.
Document 6: David Peak: David Peak is Professor of Physics at Utah State University. His current research focuses on the interdisciplinary field of complexity and computation in biological phenomena, motivated by the similarities between stomata and cellular automata. Peak was one founder of the National Council on Undergraduate Research and is on the governing board (formerly the Chair) of the National Conferences on Undergraduate Research.
Document 7: London: With 120,000 students in London, the federal University of London is the largest contact teaching university in the UK. It includes four large multi-faculty universities – King's College London, Queen Mary, Royal Holloway and UCL – and a number of smaller and more specialised institutions including Birkbeck, the Courtauld Institute of Art, Goldsmiths, Guildhall School of Music and Drama, the Institute of Education, the London Business School, the London School of Economics, the London School of Hygiene & Tropical Medicine, the Royal Academy of Music, the Central School of Speech and Drama, the Royal Veterinary College and the School of Oriental and African Studies. Members of the University of London have their own admissions procedures, and some award their own degrees.
Document 8: Robert Jameson: As Regius Professor of Natural History at the University of Edinburgh for fifty years, Jameson is notable for his advanced scholarship, his superb museum collection and for his tuition of Charles Darwin. Jameson was not at his best in the lecture theatre however, and, for the first half of his career, he grappled with his predecessor John Walker's perverse "Neptunian" geological theories. Darwin attended Robert Jameson's natural history course at the University of Edinburgh in his teenage years, learning about stratigraphic geology and assisting with the collections of the Museum of Edinburgh University, then one of the largest in Europe. At Jameson's Wernerian Natural History Association, the young Charles Darwin saw John James Audubon give a demonstration of his method of using wires to prop up birds to draw or paint them in natural positions. Robert Jameson was the great-uncle of Sir Leander Starr Jameson, Bt, KCMG, CB, British colonial official and inspiration for the "Jameson Raid".
Document 9: Edward O. Wiley: Professor Edward Orlando Wiley III is the curator emeritus of ichthyology at the University of Kansas Biodiversity Institute and professor of systematics and evolution for the Department of Ecology and Evolutionary Biology at the University of Kansas. His Masters advisor was Darrell Hall, of Sam Houston State University (retired), and his doctoral advisor was Donn E. Rosen, of the American Museum of Natural History (deceased). Wiley has published extensively in topics related to phylogenetic systematics, is a Past President of the Society of Systematic Biology (then Zoology) and was involved in the founding of the Willi Hennig Society. Wiley is known for building on and establishing conceptual advances in the evolutionary species concept, first formulated by George Gaylord Simpson. Wiley defines an evolutionary species as:
Document 10: London: A number of world-leading education institutions are based in London. In the 2014/15 QS World University Rankings, Imperial College London is ranked joint 2nd in the world (alongside The University of Cambridge), University College London (UCL) is ranked 5th, and King's College London (KCL) is ranked 16th. The London School of Economics has been described as the world's leading social science institution for both teaching and research. The London Business School is considered one of the world's leading business schools and in 2015 its MBA programme was ranked second best in the world by the Financial Times.
Document 11: Yale University: Slack (2003) compares three groups that conducted biological research at Yale during overlapping periods between 1910 and 1970. Yale proved important as a site for this research. The leaders of these groups were Ross Granville Harrison, Grace E. Pickford, and G. Evelyn Hutchinson, and their members included both graduate students and more experienced scientists. All produced innovative research, including the opening of new subfields in embryology, endocrinology, and ecology, respectively, over a long period of time. Harrison's group is shown to have been a classic research school; Pickford's and Hutchinson's were not. Pickford's group was successful in spite of her lack of departmental or institutional position or power. Hutchinson and his graduate and postgraduate students were extremely productive, but in diverse areas of ecology rather than one focused area of research or the use of one set of research tools. Hutchinson's example shows that new models for research groups are needed, especially for those that include extensive field research.
Document 12: James Mallet: He became professor of biological diversity at the Department of Biology, University College London. He was co-director of the Centre for Ecology and Evolution, a centre of excellence in research and teaching formed by University College London, the Institute of Zoology (Zoological Society of London), Natural History Museum, Imperial College, Queen Mary, Royal Holloway and Kew Gardens.
