Further research of the unicellular eukaryote, Emiliani huxleyi, revealed a unique strategy these organisms use to survive. Researchers call it the "Cheshire Cat" strategy because when they are threatened by marine viruses, they have the capability to change from sexually-capable diploid form to haploid phase and become virtually invisible to the virus, as well as to the human eye. This significant discovery enables "a clearer understanding of the origin of, and reasons for, sexual reproduction in eukaryotes,"the subjects who ultimately "invented" sexual reproduction.
