Recombination with random extracellular DNA must often cause deleterious effects. For a single-celled species this may not be a significant problem because an unlucky cell simply dies, while other colonial cells continue uninterrupted. However, for multicellular species such deleterious mutations may have severe consequences for the remaining cells.

It is a well-known fact in biology that pressures of an existential nature on a species result in two possible outcomes. The first outcome is that the species evolves. It adapts by way of biological evolution to the new conditions and survives. The second is that the species does not evolve and thus perishes.
