I found this interesting web page regarding the biological status of viruses. It's part of a series of pages on Microbial Life - Educational Resources.
I recently claimed that whether viruses were alive or not was largely moot, and that "my belief is that living entities are those that evolve via natural selection, and surely viruses should be included in that category".
Ford Denison countered that, "computer viruses could evolve by natural selection." Are there computer viruses out there evolving by natural selection? That's a scary thought!
