Yes but there should be some examples that we can see right now. At some point there is a situation where there is a mutation like the one you mentioned above. And according to what you are saying humans should speciate someday into at least 2 different species. If a mutatant develops a much more efficient brain would not they out compete the others. And why did not some dinosaurs develop speech? They would have had an advantate in hunting. Or why were they not 'smart' dinosaurs? We developed 'smartness' in only what 10 million years. The dinos had more time. Where was their tools etc. ? 68.109.234.155 00:02, 19 April 2007 (UTC)[reply]

Why are you assuming dinosaurs did not develop speech (communication)? Lizards traditionally are solitary animals, however if you have group behavior and hunting, such as with raptors; then indeed vocalizations and other methods of communicating would be very advantageous. There is no reason to think they did not develop advanced communications. - Roy Boy ⁸⁰⁰ 00:42, 19 April 2007 (UTC)[reply]

There were likely plenty of smart dinosaurs; don't assume because they are extinct they were "dumb". - Roy Boy ⁸⁰⁰ 00:42, 19 April 2007 (UTC)[reply]

We did not develop smartness in 10 million years, our predecessors were plenty smart already. - Roy Boy ⁸⁰⁰ 00:42, 19 April 2007 (UTC)[reply]

While again, you are assuming dinosaurs used no tools; let us assume they indeed did not. First to use a tool you need the ability manipulate small objects. The predecessor to many dinosaurs were based on, had claws instead of fingers... which were good for defense and killing, but not necessarily great for manipulation. - Roy Boy ⁸⁰⁰ 00:42, 19 April 2007 (UTC)[reply]

By "more time" you are assuming a number of things, that evolution is progressive and/or has a goal. It is neither. If circumstances do not encourage specific kinds of intelligence; or things are too competitive for that to happen, it won't... either for a long long time, or never. - Roy Boy ⁸⁰⁰ 00:42, 19 April 2007 (UTC)[reply]

Also, a more efficient brain in indeed good; but it does mean two species would be the outcome. As I mentioned in my example, the more likely scenario is that one sub-species replaces the other gradually; and you do not see what is even going on. Furthermore, if the brain with double the neurons; isn't more efficient, and actually would take far more oxygen and nutrition than an average brain... if those demanding needs are not met, then that individual will not meet their potential and may not even survive. - Roy Boy ⁸⁰⁰ 00:42, 19 April 2007 (UTC)[reply]

In my hypothetical, and in your question about dinosaur intelligence, I must emphasize there is no free lunch in biology. If you are smarter; great, but if it takes more to feed you than is available, then it won't matter. - Roy Boy ⁸⁰⁰ 00:42, 19 April 2007 (UTC)[reply]

the point is the theory is too encompassing. Smarter dinos should have out competed the dumber ones and within 65 millions they should have become more intelligent. and why did not sea creatures evolve in to whale types? much more efficient. do you see what i am saying?
