Of course, the concept of mosaic evolution, meant to clarify how evolution works, is often itself misunderstood. From Wikipedia:
"Mosaic Evolution is the concept that major evolutionary changes tend to take place in stages, not all at once." .. well, sort of, but that is not the main point and it is not well stated. Continuing, "...It is a pattern in evolution ..." "a" pattern? I wouldn't have said it that way. It is more like a general characteristic of macroevolution ... "... in which the rates of evolution in one functional system vary from those in other systems." .. like, different rates of mutation? of selection? No, no, that's not it, it's about timing, not rates "...For example, in hominid evolution, the dental system, locomotor system, and neurological system, evolved at markedly different rates." Almost. These differed systems have different histories. They do not co-evolve (see below). The word "rate" is ill advised in this context. I'll explain shortly.

Greg Laden has another wonderful post on his ScienceBlog page. Well worth reading the whole thing. Again, I am usually very concerned at how poorly the general public understands what the theory of evolution even states. Most of what people think is part of the theory isn't. As a matter of fact, most of what people think are part of the theory are just lies told by denialists. That is why it is incumbent upon education and individuals to fight for the truth as opposed to a rehash of lies and fables...
