George Owen MackieFRSCFRS (October 20, 1929 – August 25, 2023) was a British–Canadian zoologist who was a professor emeritus of biology at theUniversity of Victoria. Prior to this, he worked at theUniversity of Alberta Department of Zoology, which he left in 1968. Much of his research focused on invertebrate behavioural physiology. He was born inLincolnshire, England on October 20, 1929, the youngest son ofFrederick Percival Mackie. After obtaining a B.A. from theUniversity of Oxford in 1953, he obtained an M.A. and a D. Phil from Oxford in 1957. In 1982, he was made a fellow of theRoyal Society of Canada. In 1991, he was made a fellow of theRoyal Society of London.[1][2][3] Mackie died on August 25, 2023 at the age of 93.[4]
Mackie worked on jellyfish and other marine invertebrates, exploring the role of excitable epithelia as signalling pathways and analysing the neuromuscular basis of behaviour. He and Robert Meech discovered axons inAglantha that conduct two sorts of action potential: sodium-based in fast swimming and calcium-based in slow. With Sally Leys he found thathexactinellid sponges conduct electrical impulses throughout their bodies, regulating the activity of the flagella that produce the feeding current.
