Sir Gavin de Beer

Born 1 Nov 1899; died 21 Jun 1972 at age 72. Sir Gavin Rylands de Beer was an English zoologist and morphologist who contributed to experimental embryology, anatomy, and evolution. He refuted the germ-layer theory and developed the concept of paedomorphism (the retention of juvenile characteristics of ancestors in mature adults). From examination of the fossil Archaeopteryx, De Beer proposed mosaic evolution with piecemeal evolutionary changes to explain the combination of bird and reptile features. He was director of the British Museum's Natural History section (1950-60). Applying knowledge of biology (plant pollen) and geology (glaciology) to his study of original documents, he proposed the route taken by Hannibal across the Alps for his attack on ancient Rome.
