SPLICE

"I've often wondered what Mary Shelley's Frankenstein would have been like if it had been rewritten by Charles Darwin and turned into a movie by David Cronenberg. Now I do not have to wonder! It would probably be a lot like Splice, a delightfully twisted horror thriller from Vincenzo Natali, director of 1997's sci-fi nightmare Cube."

Synopsis:

Two young scientists (Brody and Polley) achieve fame by splicing human DNA with the DNA of different animals to create a new creature. In the process they ignore their society's ethical and legal boundaries. The scientists name their creature "Dren", which is initially a deformed female infant. However, it rapidly develops into a beautiful but deadly winged human-chimera.

I think this movie will give rise to interesting ethical debates regarding human cloning.

This brings into question the idea that homosexuallity is a genetically inherited trait or whether it is environmentally founded. The term animal homosexuality is one that might not even be able to be used because it applies human traits to animals

Animal Regeneration

The parallels of regenerative biology throughout the animal kingdom could unlock the differences in human regeneration, such as skin cells and animals such as the Paranais litoralis which can grow its limbs back. This relates to pluripotency within Therapeutic cloning
