Horizontal Gene Transfer Vastly Underestimated, Suggests New Study

The movement of genes between unrelated species (horizontal gene transfer, or HGT) may happen much more frequently than previously believed, allowing species to acquire new genes and functions extremely quickly, say scientists from the University of Rochester and the J. Craig Venter Institute. Their new study, appearing Science, is based on the discovery of a […]

Then, in the space of only a billion years, plants, mammals, insects, birds and other species exploded across the Earth. Now, scientists from Rice University think they may be […]
