Professor John Brookfield is a British population geneticist. He is Professor of Evolutionary Genetics at the University of Nottingham, in the School of Biology.  Professor Brookfield is interested in how the genomes evolve and has recently focussed on the evolution of DNA sequences which control development, particularly in Drosophila, and on the evolution of transposable elements. He received his BA in Zoology from the University of Oxford 1976, his Ph.D. in Population Genetics at the University of London in 1980. Following a post as Research Demonstrator in Genetics at the University College of Swansea from 1979-1981, he became a Visiting Fellow in the Laboratory of Genetics at The National Institute of Environmental Health Sciences, North Carolina from 1981-1983. Returning to the UK, he became a Lecturer in Genetics at the University of Leicester from 1983-1986. He is now Professor of evolutionary genetics at the University of Nottingham.

About the image: Charles Darwin's 1837 sketch, his first diagram of an evolutionary tree from his First Notebook on Transmutation of Species (1837) on view at the the Museum of Natural History in Manhattan. Interpretation of handwriting: "I think case must be that one generation should have as many living as now. To do this and to have as many species in same genus (as is) requires extinction . Thus between A + B the immense gap of relation. C + B the finest gradation. B+D rather greater distinction. Thus genera would be formed. Bearing relation" (next page begins) "to ancient types with several extinct forms" (Text and Img source:  Wikimedia)
