Exciting new discovery in fruit flies
August 31st 2007 07:02
From The Guardian, article by Alok Jha, science correspondent:
“Scientists have found the genes of an organism fused wholesale into the genome of an entirely separate species, raising new questions over how evolution works. The discovery suggests that simple bacteria and animals might swap entire genes more often than previously thought. Such large-scale transfer of genes would allow species to acquire entirely new functions and abilities in a very short space of time, rather than the much slower sequence of random mutations that normally evolves species over several generations.”
