Hendrik Poinar

Hendrik Nicholas Poinar (born May 31, 1969 in Utrecht, The Netherlands ) is an evolutionary biologist specializing in ancient DNA. Poinar first became widely known for successfully extracting DNA sequences from ground sloth coprolites. He is presently director of the Ancient DNA Centre at McMaster University in Hamilton, Ontario.

Education and academic career
The son of noted entomologist George Poinar, Jr. and Eva Poinar, Poinar received his B.S. and M.S. degrees from California Polytechnic University, San Luis Obispo in 1992 and 1999 respectively before earning a Ph.D. in 1999 from the Ludwig Maximilians University of Munich, after which he was a postdoctoral researcher from 2000 to 2003 at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany. In 2003 he was hired as an assistant professor in the anthropology department at McMaster University in Canada.

In a joint 2000 paper in Science, Poinar and Dr. Alan Cooper argued that much existing work in human ancient DNA has not been sufficiently rigorous to prevent DNA contamination from modern human sources, and that many reported results for ancient human DNA may therefore be suspect.

In 2003, Poinar and others from the Max Planck Institute published genetic sequences isolated from coprolites of the extinct Shasta giant ground sloth, with an estimated age of 10500 years using radiocarbon dates. This were the first genetic sequences retrieved from any extinct ground sloth.

In 2005 Poinar was reported to be working on the sequencing of the wooly mammoth genome.
