How come animals do not talk?
They communicate with each other. But why haven't they developed vocalization to the extent that we have??? Because they didn't need it to survive. Thats the answer to every question. Why does this species have this ability??? Because they needed it to survive (those that didn't have it died) Why does that species not have a certain ability??? Because they could survive without it. I'm not neccessarily defending the position- just explaining it. As a lifelong JW, I feel that I really never studied evolution and so, really should not have any opinion on it until I look into it. The books that the Borg and most other creationist movements publish on the subject have one argument- "Life is complex- therefore there was a creator." Not a really sound logical argument......
