Cass considers her own words carefully. "That's true, it won't. But if my understanding is correct, your species evolved that way because host bodies on your home planet were plentiful. At some point, that changed, and you started to want more sophisticated host bodies, which meant attacking other sentient species. Again, if my information is correct, your numbers have been greatly reduced over time. That would seem to suggest that natural selection is not in favor of this method, wouldn't it?
"I understand that accepting artificial bodies is a huge leap, but I disagree that it's like asking me to live without my skin. It's more like asking a civilization who has built its economy on enslaving other races to shift to a different way of providing for itself, without the use of slaves. All I'm asking is that you consider the prospect. It could very well prove to be the salvation of your species."
