Scientists advise caution with regard to artificial insemination method

Richard Wagner examines a classic experiment in evolutionary biology and points out pitfalls in the experimental design.

It is well known that genes are passed from one generation to the next. In addition, new genes arise regularly, although the number of genes in a particular organism does not seem to increase. The paradox has been solved by recent research at the University of Veterinary Medicine, Vienna, which shows that newly created genes are frequently lost. The spontaneous appearance and disappearance of genes enables organisms to adapt rapidly to their environment and helps drive evolution. The work is published today in the journal eLife.
