Strange but true, there is a creature that was able to survive and maintain the evolution over 80 million years to eat and utilize DNA remains of other creatures. The creature is bdelloidea. This is proof that God really keep all his creations.What is the weakest on the planet proved to be able to survive in evolution and still exist to this day. Relative bdelloidea was recently discovered and are still in the process of research it is still a lot of unknowns, including how bdelloidea magaimana suck and utilize DNA remains of other creatures and evolve asexually (divide, etc.). If we think bdelloidea can be used for genetic engineering. Following coverage:

Animals micro bdelloidea group, rotifers that live in moist soil, attracting the attention of scientists. These creatures are able to maintain the existence of species in 80 million years without sexual reproduction.
The results of a recent study conducted Alan Tunnacliffe from the University of Cambridge adds strangeness of this creature. According to him, 10 percent of bdelloidea DNA was derived from other unicellular organisms, such as fungi and bacteria.
"We do not know how the genes are transferred, but almost certainly it was done by digesting DNA from the remains of organic materials are abundant in the environment. Bdelloidea will eat anything smaller than her head," says Tunnacliffe, as quoted by LiveScience, Saturday ( 11.17.2012).
Many creatures that reproduce asexually in danger of extinction due to poor genetic diversity. However, other bdelloidea story. The creature was successfully overcome shortcomings and continue to grow until more diverse with the number of species has now reached 400.
With DNA "alien" or DNA from other creatures, bdelloidea get capital to survive. As the creature is facing drought, one of the genes in activated alien DNA chains. Genes of foreign DNA is thought to be able to produce potent antioxidants to overcome the adverse effects of drought.
Based on previous research published in the journal Proceedings of the National Academy of Sciences, in 2008, the success bdelloidea also not free of DNA repair capability. The results of this latest study published in the journal PLoS Genetics, Thursday (15/11/2012).
