- would it not be more accurate, in terms of existing biological usage,
- to talk about "hard" vs. "soft" selection? "coevolution" usually refers
- to the evolution of distinct, interacting populations, such as
- host/parasite, not intraspecific competition as you imply in the above
- example. it's not a good idea to change the meaning of existing terms.
