It takes a long time for the changes to be obviously observable. But at least some change has to occur in any given generation, in order for it to build up to 'significant' change over time. So now that we can look at genes directly, it makes sense that we would potentially be able to identify these changes.
- hellofunk 9y ago> But at least some change has to occur in any given generation This is not usually true and not typically how many species have evolved. Typically a long sequence of generations will exist with zero change, and then individual evolutionary events occur to create very rapid change in a very short period of time before stabilizing with long periods of no change again. A lot of people here are expressing what they seem to think evolution is without apparently having ever actually studied it; that is my take-away anyway.
- tempestn 9y agoInteresting. I'm unfamiliar with that position, but as you say, I'm certainly not an expert in the area. A bit of googling didn't turn up evidence one way or the other; do you happen to have a reference?
- hellofunk 9y agoMy main reference is what I was taught in an animal behavior course several years ago at university. There are some interesting books on this subject on my reading list, but I haven't yet gotten to them.
