Why
This extensive horizontal gene transfer (HGT) from the endosymbiont Blattabacterium cuenoti to cockroach genomes provides a clearer picture of bacterial DNA transfer into an animal genome.
The Frontline Impact
How this affects you
This discovery challenges previous assumptions about the rarity of horizontal gene transfer in complex organisms like animals, suggesting that such transfers have played a significant and persistent role in the evolution of cockroach genomes for millions of years.
