No. Some species, maybe. Took only about 10,000 years for a polar bear to evolve.
But pacing of evolution is highly variable depending on selection. Typically, there are brief periods of strong directional or disruptive selection, followed by long periods of stabilizing selection.
The were some major changes to make bears and dogs out of generalized carnivores. Humans haven't changed that much from Australopithecines. The major changes are in the cranium, with the postcranial skeleton very similar to primitive hominins.
So not so much change required.
I disagree, I feel that a Change From Lucy to Man, is Much larger, than A bear, to a Bear.
We have an ape-like skull.
We have a Human Skull, a Human Like Skull. Ape's have Ape Like Skulls, How hard can this really be for you?
Specific changes are reduction in size of facial bones and increase in the size of the skull, the loss of the simian shelf, and the consequent development of a chin. Neotony left us looking more like a juvenile ape, and the repositioning of the foramen magnum (which is farther forward on young apes) means our heads sit on top of the spine which repositions the larynx, making complex speech possible, but also making it likely we will choke on food.
I'm Sorry, How did we Get Chins, Again? I heard that Evols believe that the Chin formed because We Started Talking, LOL!!!!
The rest of our bodies are remarkably like late Australopithecines. Would you like me to show you?
Please Do, I Love the Australopithecine. LOL!!!! How much of it's Skull did we Find, agian?
Wrong. Bears vary a great deal more than Australopithecines vary from modern humans.
I disagree, the fact that we cannot Mate with Apes, shows that they are very much Different From us, than Bears are from each other. Your the Guy that thinks Wolves are A different Species than Dogs, even though you have Been Proven Wrong, Directly.
A Polar Bear, is still a bear, It is Capable of Reproducing with other Bears, that's how we know, it is still the same Species as Bear. No Speciation has taken Place.

Your Definition of Species is Flawed, due to your Unfounded Bias of Evolution.
Lucy, well what there is of Her;
-----------------------------------------------------------------
Man;
-----------------------------------------------------------------
What Evols think those Few Fossils Add up too;
-----------------------------------------------------------------
Here is what they Constructed with their Evol Minds from the Lack of Evidence;
Odd, She Looks more like an Ape than a Woman.... Given Her Size, Skull, and Many of her Other Ape like Appearances, which Make Her Different Than Man.
Did you know, that Evolutionists Used to believe that We Descended from Cave Men, Now they Think that We Lived along Side Cavemen, and Actually Interbred with them. Hey, You know what that Means? These cave Men, are Really Humans. LOL!!!
Lucy of Course is no cave man, Lucy is an Ape, which is not the Same Species as Man, whatsoever.
Lucy is A Lie, composed of a Young Woman's Pelvis, And an Ape's Skull, and Femur. Her Feet were never Found, so we don't know if She Had Monkey Hand Feet or People Feet.
The Reason Evols think that she Had Man Feet, is because they found Fossilized Foot Prints, which look like Man's Foot Prints, Supposedly made 3 Million years ago. So, Instead of Saying the Obvious, "Hey We Found People Prints", they say, "HEY Lucy must have Had Feet Like a Man", and Not Hand Feet, After All Lucy's Kind is the Only Being Walking around Back then; That means She must have Man Feet, and be on her Way to becoming Man!!!!!
Leaping Lemur Logic, I tell you, Leaping Lemur Logic.
Here is Your Question, Barbie, or Any other Evol, that Feels Up to the Challenge;
How Identical to a Young Woman's Pelvis, is Lucy's Pelvis believed to Be?
Shouldn't it be, by the Theory of Evolution, in Between an Ape's And Woman's Pelvis?
