Yup!
Now let me get this straight.....cave paintings from primitive humans indicate that horses used to have spots like a deer?
Indeed.
At what period do you assume that humans were painting in caves?
A small number of caves, including 25,000-year-old Pech Merle in southern France, feature horses painted white with black spots. Some archaeologists have argued that this leopard-like pattern was fanciful and symbol laden rather than realistic. Indeed, in a 2009 analysis of DNA from the bones of nearly 90 ancient horses dated from about 12,000 to 1,000 years ago, researchers found genetic evidence for bay and black coat colors but
no sign of the spotted variety, suggesting that the spotted horse could have been the figment of some artist’s imagination. Although researchers can only speculate on what prehistoric artists were trying to express, hypotheses range from shamanistic and ritualistic activities to attempts to capture the spirit of horses and other animals that ancient humans hunted.
But in a new paper published online today in the Proceedings of the National Academy of Sciences, the same team reports finding that
spotted horses did indeed exist around the time that cave artists were doing their best work. The researchers, led by geneticists Arne Ludwig of the Leibniz Institute for Zoo and Wildlife Research in Berlin and Michael Hofreiter of the University of York in the United Kingdom, analyzed DNA from an older sample of 31 prehistoric horses from Siberia as well as Eastern and Western Europe, ranging from about 20,000 to 2,200 years ago. They found that 18 of the horses were bay, seven were black, but six had a genetic variant — called LP — that corresponds to leopard-like spotting in modern horses. Moreover, out of 10 Western European horses estimated to be about 14,000 years old, four had the LP genetic marker, suggesting that spotted horses were not uncommon during the heyday of cave painting.
If so, the team argues, prehistoric artists may have been drawing what they saw rather than creating imaginary creatures. Prehistoric horses came in at least “three coat color"
Ludwig says, “and exactly these three [colors] are also seen in cave paintings. Cave art is more realistic than often suggested.”

I assume that it was not 55 million years ago when Eohippus supposedly roamed the earth......his closest relative in the timeline has no spots.....so where does the caveman get his ideas? Are there not spotted horses to this day? Why not make them all spotted like these guys?
Aren't the spots just a visual ploy to reinforce the "suggestion" that horse ancestors resembled deer?
We now have horse DNA going back 700,000 years. This now sequenced genome offers a glimpse at the ancient horse and how equine genes have evolved. Genes that are involved in immunity, the sense of smell, and muscle development have all changed significantly since then, color appears to to have been stable, Bay, Black and LP. Does this guarantee that was so 55 million years ago? No, it does not, but this data, combined with the sort of protective adaptation that even you agree with and the guiding principle of uniformitarianism, makes those color schemes very probable.
Of course not....there is nothing straight about evolution. It just gets curiouser and curiouser.....fantasy built on fantasy, masquerading as science.
Now. now. I know how inordinately proud you are of you level of ignorance, but this borders on hubris.
That is pure assumption. There is nothing linking these animals but similarity, which could be just as easily explained by creation. One Creator, using the same raw materials and using a base design that works in many applications. Doesn't science do the same thing?
Clearly the hubris of ignorance.
I have as much solid verifiable evidence as you do.
But we have already determined that you have not the vaguest clue as to the depths of verifiable evidence that I posses and you've stipulated that even if you did you are too biologically ignorant to understand it. YOU CAN'T HAVE IT BOTH WAYS.
Ah...the old 'I'm smarter than you, let me flash my credentials' defense
.....you could well be vastly superior to me in intellect and in academic achievement, but that in itself just makes your position more monumentally flawed in your acceptance of something that is not backed up by true science at all. You "believe" in evolution because you think it makes you appear to be superior to those with less intelligence who accept the fantasy of a Creator. But the truth is, the fantasy you accept actually requires more faith and credulity than mine.
No, I understand evolution and it's processes and I understand the immense weakness of your lack of evidence. I take it on your word that you do not understand evolution and it's processes and that you have no grasp of the fullness of the information that modern science has at it's disposal. I am not resting on my credentials, in fact, I have not (save debunking your "common sense" foolishness) mentioned them,, though I have in the course of this conversation drawn on them to demonstrate the abject weakness of yours. If your Bible study as as weak as your biological study ... would any of your fellow travelers take you seriously? I expect not. Why do you expect us to take you seriously?
I can and I did.
You have no "scientifically verifiable" evidence of a chain of descent, with creatures morphing into other creatures. It is only a chain if it has links.....there are no verifiable links. Adaptation does not provide them.
You can bloviate that same phrase till you're blue in the face, but you know what they say ... empty barrels make he most noise.
That is just the point.....all the "scientific proof" is alleged, supposed, imagined....not proven. The conclusions were based more on what was an expected outcome and interpreting the results to fit that presupposition.
Science does not deal in "proof" rather it deals in probabilities.
Misconceptions about the
nature and practice of science abound, and are sometimes even held by otherwise respectable practicing scientists themselves. I have dispelled some of them (misconceptions, not scientists) in earlier posts (for example, that
beauty is in the eye of the beholder,
beauty is only skin-deep, and
you can’t judge a book by its cover). Unfortunately, there are many other misconceptions about science. One of the most common misconceptions concerns the so-called “scientific proofs.” Contrary to popular belief, there is no such thing as a scientific proof.
Proofs exist only in mathematics and logic, not in science. Mathematics and logic are both closed, self-contained systems of propositions, whereas science is empirical and deals with nature as it exists. The primary criterion and standard of evaluation of scientific theory is evidence, not proof. All else equal (such as internal logical consistency and parsimony), scientists prefer theories for which there is more and better evidence to theories for which there is less and worse evidence. Proofs are not the currency of science.
Proofs have two features that do not exist in science: They are
final, and they are
binary. Once a theorem is proven, it will forever be true and there will be nothing in the future that will threaten its status as a proven theorem (unless a flaw is discovered in the proof). Apart from a discovery of an error, a proven theorem will forever and always be a proven theorem.
In contrast, all scientific knowledge is
tentative and
provisional, and nothing is final. There is no such thing as final proven knowledge in science. The currently accepted theory of a phenomenon is simply the best explanation for it
among all available alternatives. Its status as the accepted theory is contingent on what other theories are available and might suddenly change tomorrow if there appears a better theory or new evidence that might challenge the accepted theory. No knowledge or theory (which embodies scientific knowledge) is final. That, by the way, is why science is so much fun.
Further, proofs, like
pregnancy, are binary; a mathematical proposition is either proven (in which case it becomes a theorem) or not (in which case it remains a conjecture until it is proven). There is nothing in between. A theorem cannot be kind of proven or almost proven. These are the same as unproven.
In contrast, there is no such binary evaluation of scientific theories. Scientific theories are neither absolutely false nor absolutely true. They are always somewhere in between. Some theories are better, more credible, and more accepted than others. There is always more, more credible, and better evidence for some theories than others. It is a matter of more or less, not either/or. For example, experimental evidence is better and more credible than correlational evidence, but even the former cannot prove a theory; it only provides very strong evidence for the theory and against its alternatives.
The knowledge that there is no such thing as a scientific proof should give you a very easy way to tell real scientists from hacks and wannabes. Real scientists never use the words “scientific proofs,” because they know no such thing exists. Anyone who uses the words “proof,” “prove” and “proven” in their discussion of science is not a real scientist.
The creationists and other critics of evolution are absolutely correct when they point out that evolution is “just a theory” and it is not “proven.” What they neglect to mention is that
everything in science is just a theory and is never proven. Unlike the Prime Number Theorem, which will absolutely and forever be true, it is still possible, albeit very, very, very, very, very unlikely, that the theory of evolution by natural and sexual selection may one day turn out to be false. But then again, it is also possible, albeit very, very, very, very, very unlikely, that monkeys will fly out of my *** tomorrow. In my judgment, both events are about equally likely.

This is obvious to those looking at evolution from the outside. 'In house', I just see you all being as blind as each other....patting one another on the back and perpetuating your pet theory with nothing but suggestion.
That is simply because you do not understand, as you demonstrate with each post, how science works, you are criticizing a saw because it makes a lousy hammer. You'd do better to equip your tool kit with both a saw and a hammer.
