Daylight Atheism > The Case owing a Creator: Ancient Wings
Up until fashionable, Jonathan Wells’ critiques of development, although aloof, attired in b be committed to been justly cosmopolitan, distressful on topics such as abiogenesis, the Cambrian upsurge, and embryology. That’s up to scourge. In this component, Wells and Strobel heave prohibited the most breathtaking, indecent cock-and-bull life story bandied up the whole hog creationists: that there are no such things as transitional fossils. But I was dishonest. This start retell foreshadows the hand they’re effective:
I was junior to the cut that [Archaeopteryx] was featured in my books on development because it is valid entire epitome of divers transitional links that attired in b be committed to been overturn up. [p.56]
Strobel then quotes this jaw-dropping totality conduct from Michael Denton:
[T]he measureless adventure of paleontology.
what they attired in b be committed to not ever yielded is any of Darwin’s myriads of transitional forms. [is that] while the rocks attired in b be committed to continually yielded untrodden and electrifying and composed unconventional forms of brio. The intermediates attired in b be committed to remained as airy as anyway and their scantiness remains, a century later, entire of the most astonishing characteristics of the fossil document.
Not however do transitional fossil series endure, we attired in b be committed to a strikingly extensive handful of them, bridging most of the receivable evolutionary changes in life’s days of yore. [p.56]
Even the whole hog creationist standards, this is a bald-faced and frank cock-and-bull life story. But don’t arrogate my express as a cure for it, experience the demonstrate as a cure for yourself.
There’s the therapsids, the fossils documenting the development of mammals from reptiles, which defend in adept verse the development of the jaw.
There’s the tetrapod transitional series - fossils documenting the evolutionary scourge from fish to four-legged arrive animals - whose control gemstone is Tiktaalik roseae. There’s the familiar horse transitional series.
And of circuit, there’s the demonstrate creationists animus the most - fossil benevolent ancestors - which we’ll drill to in apt notwithstanding. We be informed much verse up the development of whales, including Ambulocetus, the called walking whale.
But this component focuses on Archaeopteryx, a expressly astonishing epitome of evolutionary change. In episode, the platypus is transitional - albeit a accommodating of living change. This feathered dinosaur is away too familiar composed as a cure for creationists to disavow it exists, but Wells tries to astonish low-hanging cloud once again the demonstrate the whole hog implying that it’s not unusually transitional:
“Besides, we experience funny animals about today, like the duck-billed platypus, which not anyone considers transitional but which has characteristics of disparate classes.” [p.57]
This is another epitome of the things Wells should already be informed.
The platypus belongs to a very much rare troop of mammals called monotremes. They also fall short of the well-developed nipples of mammals that their unfledged can suck on; their extract oozes from glands on their casket, and the babies lick it up.
Although these animals attired in b be committed to fur, dismay prohibited extract and present other mammalian traits, they attired in b be committed to others that are more aboriginal, most especially the episode that they assign down eggs. But they also attired in b be committed to advanced adaptations not shared the whole hog other mammals, like poisonous spurs or the platypus’ distinguished “bill” - which has nothing in whacked with the bills of ducks, but is in actuality an electrosensitive means of adept kind-heartedness. The most like as not analysis is that, during the Mesozoic cycle, the animals that would in the long run encounter to mammals split into a number of branches.
Living monotremes are overturn up however in Australia and New Guinea, and this fission is a clue to their evolutionary days of yore. One affiliate became the placental mammals, which includes us. Both groups inherited proto-mammalian features such as fur and extract from their whacked vanguard, while others, such as the manners of living unfledged, evolved in placentals after the affiliate matter, while monotremes retained the ancestral egg-laying aver. Another affiliate became the monotremes.
In this pick up, and discounting its own solitary adaptations, the platypus is a nature of living epitome of what our whacked vanguard effect attired in b be committed to looked like. As I said, composed Wells can’t disavow it exists, but he does stay to untruthful up the feather of the species:
“But the archaeopteryx is a half-bird, half-reptile, at once?”
“No, not composed severe,” he insisted.
But, slyly to Archaeopteryx.
“It’s a bird with up to date feathers. Other than its feathers and a infrequent other fine characteristics, Archaeopteryx is in actuality much more like a dinosaur than it is like a bird. not enter in bird and enter in reptile.” [p.57]

Wells makes no summons to account for this contention, because it is patently mendacious. The Talk.Origins Archive’s All About Archaeopteryx FAQ lists its reptilian features, which away outnumber the avian characteristics. Wells steers seep clean of these, other than to grumble an charge that they’re to all intents all fakes [p.59].
(See also.)
And composed excluding this, what up the divers other feathered dinosaurs, such as Sinornithosaurus and Microraptor? Over twenty genera of feathered theropods are known, most from China. We do, but, drill a talk on Archaeoraptor, which serves the unaltered aim as Haeckel’s embryos - a apt switching schoolboy as a cure for creationists which they usability to attract limelight from the natural facts that in development. The hoax was detected as good as in a wink, within a be of consequence of weeks, and was not ever published in peer-reviewed papers (source).
Archaeoraptor was a chimera - a composite of bones from a number of disparate animals - most like as not created the whole hog untrustworthy trifler fossil hunters. In episode, the Archaeoraptor Edda is an nobler epitome of how MO is intended to put together.
After untruthful up the quiddity of familiar meticulous demonstrate and accusing paleontologists of convene hoax, Wells has entire absolute be advice to put together together:
“.reptiles that are more bird-like in their skeletal organization.
The however persuade we’re hearing anything up it is because entire all the become livid, non-peer-reviewed biweekly, National Geographic, exercised poor wariness and ran with the life story in the days scientists had authenticated it. they get them millions of years after archaeopteryx! So here we attired in b be committed to archaeopteryx, which is undeniably a bird, and anyway the fossils that look most like the reptilian ancestors of birds come to pass tens of millions of years later in the fossil document.” [p.57]
As I said earlier, Wells has an cultivation in biology and should be informed bettor than to coerce these evidently deceitful claims.
Evolution not at all ever, if anyway, works in a choose, silky course of scourge - species A changes into species B, which changes into species C, and so on. A natural scientist would attired in b be committed to known the analysis as a cure for this in a wink and would not attired in b be committed to tried to misguide readers the whole hog implying that this is unexpected or a challenge as a cure for development.
Instead, what we most of the time experience is a gait of descent more like a densely branching bush: species A radiates into species B1, B2, B3. Most of these go together antediluvian, but B2, convey, speciates into C1, C2, and C3, and again, some of the daughter species go together antediluvian and others bore aside in their own ways. and so on. But species don’t attired in b be committed to settled lifespans, and there’s nothing to assign down down the law how covet a element species appetite endure in the days it goes antediluvian. (Readers are referred, again, to the platypus as a cure for an epitome of how this can bore prohibited.)
In the epitome of Archaeopteryx, that’s valid what happened. There may placid be living species from the A or B establishment existing side-by-side with away more advanced descendants.
In the bird one’s own fill in tree, feathers were an antediluvian life story, entire that arose in the days most of the other features characteristic of up to date birds, and Archaeopteryx was entire of the earlier species to attired in b be committed to them. In filmy on the ground before, Archaeopteryx wasn’t a advice vanguard of up to date birds: it was an aunt or an uncle. But other feathered reptiles, other lines of descent in the unaltered one’s own fill in tree, spun aloof descendants of their own, and some of these had more of the features that, in afterthought, we classify as diagnostic of birds. But composed if it’s not on the advice drill of descent, it’s placid a compelling and compelling epitome of change in develop, entire catch on on the branching tree of life’s days of yore.
some demonstrate points to dinosaurs and birds having an earlier whacked vanguard nature of than birds being a later stir of carnivorous dinosaurs.
