Definition of Evolution

I've been meaning to read more Talk Origin articles and thus, there I was browsing through its archives.

I came across this definition of Biological Evolution which was worth noting.

The author Laurence Moran points out that common misconceptions about evolution seem to stem from bad definitions of the term evolution itself.

Quote:

... evolution is simply "a process that results in heritable changes in a population spread over many generations" ...

This was an enlightening article whereby I paused at the end of my reading to reassess my own misinformed definition. The subsequent dictionary surfing was quite telling as well.
