Quotations

"
Between his self-knowledge, which was considerable, and his vanity, which was immense, he had created a strange hybrid animal, and called it by his own name."
Stevenson, Robert-Louis. "Tales and Fantasies" Farlex. Accessed 11 Nov. 2010. <>

"The mule always appears to me a most surprising animal. That a hybrid should possess more reason, memory, obstinacy, social affection, powers of muscular endurance, and length of life, than either of its parents, seems to indicate that art has here outdone nature. Of our ten animals, six were intended for riding, and four for carrying cargoes, each taking turn about"
Darwin, Charles. "The Voyage of the Beagle" Falex. Accessed 11 Nov. 2010. <>


Annotated Bibliography

Lemmon, Emily Moriarty, and Alan R. Lemmon. "REINFORCEMENT IN CHORUS FROGS: LIFETIME FITNESS ESTIMATES INCLUDING INTRINSIC NATURAL SELECTION AND SEXUAL SELECTION AGAINST HYBRIDS." Evolution 64.6 (2010): 1748-1761. Academic Search Complete. EBSCO. Web. 11 Nov. 2010.

This article discusses findings in experiments on hybrid species reproductive viability, frogs in particular. It was found that in this species, the sterilization of hybrid individuals was only partially attributed to natural selection against reproduction. Another cause of limited viability is the species sexual selection against hybrid individuals.

"Maladaptive hybridization is hypothesized to be an important force driving the evolution of reproductive isolation between closely related species."

This article was interesting because it describes a natural safeguard process against specific hybridization, in this case, scientifically imposed by humans. The article was scientific in nature and absent of any bias.


Relates

This idea relates to my work because, for one, genetic engineering across species to produce hybrids is commonplace in human societies. (Mules) Also, often in my images, I pose an anatomical conundrum between humans and non-human forms, symbolic of the power struggle between man and wild. Scientifically, hybridization causes a natural filtration process to occur to prevent the viability of such genetic traits, which is an interesting conceptual defense mechanism I think relates to this grotesque struggle I am portraying.
