Sweet find.

At the risk of getting the it's-just-a-cartoon-don't-take-things-so-seriously response, I have one question:

Do viruses evolve into other viruses?

I guess they can evolve into a different variation of the same virus.
Take the common cold for example.

Indeed. That can be seen all over the natural world. Called natural selection and survival of the fittest, if junior high sience serves me correctly.

How is that evolution?

Evolution:
a process in which something passes by degrees to a different stage
(especially a more advanced or mature stage); "the development of his
ideas took many years"; "the evolution of Greek civilization"; "the
slow development of her skill as a writer"

Aren't viruses doing the same thing here. Passing from stage to a more advanced stage. How is that not evolution.

I guess when I think of evolution, I think of the process that must have taken place to move from one species to another...not the natural changes that take place in species of the same genetic makeup.

It seems to me (please correct me if I am wrong) that viruses adapt to their environment, just as any other life form does. This is what Darwin observed, and what is observable today. What I have never seen reported is evolution from one life form to another (cat to dog, ape to human, fish to lizard).

Isn't this what humans have done too.

We've evolved into a more self-favourable life form.

Evolution big or small, major or minor is evolution.
