There are genes in bdelloid rotifers that seem to have come from bacteria, fungi, and plants. This suggests they arrived by horizontal gene transfer (HGT). The capture and use of exogenous (~foreign) genes seems to be important in bdelloid evolution. The team led by Matthew S. Meselson at Harvard University showed that, despite the lack of sexual reproduction, bdelloid rotifers do engage in genetic (DNA) transfer within a species or clade. The method used is not known at present. Bdelloid rotifers currently hold the 'record' for HGT in animals with ~8% of their genes from bacterial origins.
