I also imagine that it won't be too long before the WT has to admit that "evolution" by the strict dictionary definition is a reality.
You may have hit on something there. The WTS never drops a bomb like change in doctrine. They set it up with subtle changes, such as redefining words and phrases. Doesn't matter that it has no basis in real life or fact, but in dubland, if you control the information, you can make the people believe whatever you want.
With this confusing, somewhat contradictory statement, they may be setting up a slow change in how they define 'evolution' and how they can slowly convince their followers that belief in 'evolution' is consistent with their doctrines. It's not an overnight thing. It'll take a couple years or more.
We should keep an 'evolution watch' on em and see what they print over the next couple of years. Naw... I've gotta life. Don't really care that much...
