George O. Poinar Jr. (born April 25, 1936) is an American entomologist and writer. He is known for popularizing the idea of extracting DNA from insects fossilized in
amber Amber is fossilized tree resin that has been appreciated for its color and natural beauty since Neolithic times. Much valued from antiquity to the present as a gemstone, amber is made into a variety of decorative objects."Amber" (2004). In ...

in the Department of Entomology, Division of Insect Pathology. There, and during travels around the globe, he performed research on the axenic culture of nematodes, nematode parasites of insects and the fossil records of insects and nematodes in amber. In 1992 a team consisting of Poinar, his wife entomologist Roberta Poinar, his son Hendrik, and Dr. Raúl J. Cano of California Polytechnic State University successfully extracted insect DNA from a Lebanese

cast doubt on the DNA results, but not on the authenticity of the amber samples. In 1995, George and Roberta Poinar, a fellow researcher from Berkeley, moved to Oregon, where they opened the Amber Institute. Upon his move to Oregon he received a courtesy appointment to the Department of Entomology of

Strychnos electri ''Strychnos'' is a genus of flowering plants, belonging to the family Loganiaceae (sometimes Strychnaceae). The genus includes about 100 accepted species of trees and lianas, and more than 200 that are as yet unresolved. The genus is widely dis ...
