After learning all about bears my four and three old were overheard having this conversation:

3 year old, “I’m scared of the bears in Colorado.”

4 year answers, “There’s no reason to be scared because number one, it’s winter time and bears hibernate during winter, remember? And number two, Colorado only has fuzzy bears.”

Another conversation they had while playing:

3 year old, “Let’s put all the Panda bears in the raccoon family.”

4 year old, “No, we can’t do that. Don’t you remember that scientists have changed their family? They used to be in the raccoon family and now they’re in the bear family.”
