I'm hoping you can help me brainstorm. Octavia Butler uses the concept of 'xenogenesis' in many of her works (not just the Lillith's Brood trilogy), and I'm working on an article for a magazine that explores this concept of, well, deliberately breeding with alien critters.
What *other* science fiction can you think of that explores this theme? Or does it come up in other pop-culture realms beyond scifi?
Thanks in advance for your ideas.
