Wrong. Any change in the genetic makeup of the spotted owls that gives them an advantage in the "next to the Quickie Mart" environment would be an example of evolution. I don't know whether or not this has occurred, but there need not be a large change to the population such as you suggest for evolution to have occurred.
Seems as how SO's were pretty rare in pre development days, nearly non-existent. They live in trees, and hunt best in open fields where they can catch critters for dinner.
But when loggers started clearcutting, the SO population went up considerably, because there were now more fields for them to hunt in, and THEN they were discovered by enviros who made the point that they lived in large trees, not in clearcut fields.
The point is that loggers actually caused the population of Spotted Owls to grow, not decline.
Result - enviros have shut their trap on Spotted Owls.
