Comparing genomes of different species can tell you when new genes evolved and what they do for their respective hosts. But pinpointing the ancestry of any given gene is a complex computational task. Now, powerful new software makes gene “archeology” considerably easier, reports a team of investigators at Carnegie Mellon University. The scientists, who are making this software publicly available for the first time, are presenting their findings Monday, May 16, at the RECOMB meeting in Cambridge, Mass.
