We've really got to do something about these extraneous question marks.
Meanwhile, "One Species? Genome Discovered Inside Another?s"
Scientists at the University of Rochester and the J. Craig Venter Institute have discovered a copy of the genome of a bacterial parasite residing inside the genome of its host species.
The research, reported in today?s Science, also shows that lateral gene transfer?the movement of genes between unrelated species?may happen much more frequently between bacteria and multicellular organisms than scientists previously believed, posing dramatic implications for evolution, pest, and disease control.
Seems there's a parasite called Wolbachia, which "has implanted itself inside the cells of 70 percent of the world?s invertebrates". Now they've "found at least one species where the parasite?s entire or nearly entire genome has been absorbed and integrated into the host?s. The host?s genes actually hold the coding information for a completely separate species.?
Didn't I mention something about co-option in my last message? ?Here it is, on a grand scale. ?Lynn Margulis is going to win a Nobel prize yet!
