Science Daily: Hundreds Of Natural-selection Studies Could Be Wrong, Study Demonstrates.
ScienceDaily (Mar. 31, 2009) — Scientists at Penn State and the National Institute of Genetics in Japan have demonstrated that several statistical methods commonly used by biologists to detect natural selection at the molecular level tend to produce incorrect results.
"Our finding means that hundreds of published studies on natural selection may have drawn incorrect conclusions," said Masatoshi Nei, Penn State Evan Pugh Professor of Biology and the team's leader. The team's results will be published in the Online Early Edition of the journal Proceedings of the National Academy of Sciences during the week ending Friday 3 April 2009 and also in the journal's print edition at a later date.
Nei said that many scientists who examine human evolution have used faulty statistical methods in their studies and, as a result, their conclusions could be wrong.
