| dbo:abstract | Brian Keith Hall (* 28. Oktober 1941 in Port Kembla, New South Wales) ist ein australisch-kanadischer Entwicklungsbiologe und Hochschullehrer an der Dalhousie University in Halifax (Nova Scotia). Hall studierte Zoologie an der University of New England in Armidale mit dem Bachelor-Abschluss 1963 und 1965 und der Promotion (Ph.D.) 1968. Die Dissertation bei war über die Differenzierung von Knochen und Knorpel in Hühner-Embryos. Zusätzlich erhielt er 1978 einen D.Sc. in Biologie. Von 1968 bis zur Emeritierung 2007 forschte und lehrte er an der Dalhousie University. Er ist bekannt für den Vorschlag, dass die Neuralleiste im Embryo bei Wirbeltieren ein viertes Keimblatt ist neben Endoderm, Mesoderm, Ektoderm. Das ist nach Hall eine Besonderheit von Wirbeltieren und erzeugt eine Reihe neuer Organe (Knochen, Knorpel, sympathisches Nervensystem). Außerdem befasst er sich mit evolutionärer Entwicklungsbiologie (Entwicklung des Bauplans der Tiere) und war wesentlich an der Verbindung der Disziplinen Evolutionsbiologie und Entwicklungsbiologie beteiligt (Evo-Devo). Dabei betonte er auch die Rolle epigenetischer Wechselwirkungen von Geweben bei der Entwicklung. Er ist Fellow der Royal Society of Canada (1985) und Mitglied der American Academy of Arts and Sciences (2002). Von 2003 bis 2005 war er Killam Research Fellow und 2005 gewann er den Killam Prize. 2014 wurde er Ehrendoktor der University of Calgary. 2001 gehörte er zu den ersten Empfängern der Alexander-Kowalewski-Medaille. (de) Brian Keith Hall FRSC (born 1941) is the George S. Campbell Professor of Biology and University Research Professor Emeritus at Dalhousie University in Halifax, Nova Scotia. Hall has researched and extensively written on bone and cartilage formation in developing vertebrate embryos. He is an active participant in the evolutionary developmental biology (EVO-DEVO) debate on the nature and mechanisms of animal body plan formation. Hall has proposed that the neural crest tissue of vertebrates may be viewed as a fourth embryonic germ layer. As such, the neural crest - in Hall's view - plays a role equivalent to that of the endoderm, mesoderm, and ectoderm of bilaterian development and is a definitive feature of vertebrates (as hypothesized by [1983]). As such, vertebrates are the only , rather than triploblastic bilaterian animals. In vertebrates the neural crest serves to integrate the somatic division (derived from ectoderm and mesoderm) and visceral division (derived from endoderm and mesoderm) together via a wide range novel vertebrate tissues (bone, cartilage, sympathetic nervous system, etc...). He has been associated with Dalhousie University since 1968. Since his retirement in 2007, he has been University Research Professor Emeritus and Emeritus Professor of Biology. (en) |
