way to be current ..... science was warning it appeared to be a composite, national Geo ran with the story anyway (popular science magazines dont have
the same standards as scientific journals) 3-4 months later it was proven a composite fake
found that the head and upper body actually belong to a specimen of the primitive fossil bird Yanornis.[1] A 2002 study found that the tail
belongs to a small winged dromaeosaur, Microraptor, named in 2000.[2] The legs and feet belong to an as yet unknown animal.[3][4]
the ironic thing is your first article doesnt mention which dromaeosaur the tail bellonged to, and the simple answer is becasue it belonged to
microraptor
Microraptor
zhaoianus
Microraptor
gui
both these fossils are complete single slab of rock so no this one isnt a composite some chinese farmer glued togather, and we have more then 1 fosil
of both species
and what did our friend microraptor look like in real life with a little artistic help it looks like this
yepp a 4 winged feathered gliding dinosaur, it didnt have the muscle for powered flight but it had rthe wing capacity to glide a fair old distance
rather then discredit the dinosaur to bird hypothesis it enhanced it, it gave us 1 of 2 new species of microraptor and when they asked the chinese
farmer that glued it together which area he found the parts it gave them an idea where to look, bad chinese farmer for making a fake for cash

good chinese farmer for later helping science
yay lets beat up the strawman
The ridiculous reptile to bird theory
And then there is common sense. In a popular evolutionary explanation, here's how reptiles evolved into birds: They wanted to eat flying insects that
were out of reach. So the reptiles began leaping, and flapping their arms to get higher. Over millions of years, their limbs transformed into wings by
increments, their tough reptilian scales gradually sprouting soft feathers.
they wanted to fly and jumped up and down? yeah like fish flopped
around on land until they grew lungs ..

books arnt that hard to read ya know
shall we look at just how hard it is to turn a birds scales to soft feather? about as hard as getting them to grow teeth
atavisms are the name of the game, genetic material left over from ancestors which under certain circumsatances can be flicked back on to cause what
would be considered an abnormality in the present species
becasue birds descended from dinsoaur directly or an earlier lizard as Feducha Et Al believes the genes to form its beak and the genes to form its
feathers have been found to be modified versions of earlier genes
where as the gene for teeth in reptiles continues to run until teeth are formed in the fetous in avarian reptiles(birds) it switches off early, if you
restart the gene and let it run as it did in its earlier ancestors the beak doesnt form leaving a quasi jawbone with teeth (conical teeth the closet
living species that display these teeth are corcodillia), yes hens teeth arnt all that rare if your good at embryology
now birds have scaled legs(depending on the bird some are quite tough) so what does it take to transform hard cale to feather? you guessed it gene
reactivation, feathers were just a mutation that altered the stop point of gene expression, turn the gene back on and those hard scales form feathers
But the theory suffers when scrutinized. According to natural selection, a physical trait is acquired because it enhances survival.
not
really if yoou actually scrutinise it not just say this is silly cant be true and put your fingers in your ears
The problem is, wings would have no genuine survival value until they reached the point of flight. Birds' wings and feathers are perfectly
designed instruments. Those with crippled or clipped wings cannot fly,
ohh but they can glide, they can glide from 1 tree to another to reach
food escape predators, and if they fall even half a wing will slow your fall and aid your survival better then no wing at all
and feathers came before powered flight, so before they helped with gliding and fall breaking they provided warmth to help regulate body temperature,
we find feathered dinosaur long before they had the ability to fly or glide(and lots of them with feathers were to big to do so anyway)
so its not a problem at all
and are bad candidates for survival. Likewise, the intermediate creature whose limb was half leg, half wing, would fare poorly -- it couldn't
fly, nor walk well. Natural selection would eliminate it without a second thought.
why? it would still have the ability to climb, and some ability to glide and some ability to break its fall. that all aids survival so chances are
natural selection wouldnt kill them all off
and thats 1/2 arm 1/2 wing not leg silly
Let's raise an even more fundamental question: Why aren't reptiles today developing feathers?
they are small cold blooded and dont
need to regulate thier body temperature like warm blooded dinosaurs? (btw crocodillians have been shown to have once been warm blooded too at one
point)
becasue it takes a random mutation and the right one hasnt triggered in them?
becasue it would harm not aid them so natural selection would have killed them off?
Why aren't fish today growing little legs, trying to adapt to land? Shouldn't evolution be ongoing?
mudskipper? lungfish? theres
quite a few fish that can travel over land
but competition on land is now as fierce as in water so switching from one to the other permanently doesnt provide the benefits it once did so natural
selection works against it
The complete lack of a fossil record
Supposedly invertebrates evolved into the first fish. But despite millions of fossils from both groups, transitional fossils linking them are
missing.
wernt we on about reptile > avarian reptile?
missing? no we havnt found any missing links once found they stop bieng missing
Insects, rodents, bats, pterodactyls and numerous other life forms appear in the fossil record with no trace of fossils showing how they
developed.
bald faced lie
The main point: If evolutionary theory is true, we should find the innumerable transitional forms Darwin predicted would be in the geologic
record. We shouldn't find just a handful, but billions of them.
will thousands do?
and no only a very small percentage will fossalise for us to find, fossils can only transform to fossils under certain conditions, most get eaten
destroyed and dragged away, others are in soil conditions that destroy the bone (acid soil is a bitch) while others are eroded before we find them and
many havnt been found yet
the fact we can use what we already have to make predictions on what to find where and go hunt down specifics transitionals says our fossils records
plenty accurate
we know where to look for whale transitionals and fish > tetrapod, tiktaalik wasnt a chance find they went specifically looking for a transitional
fossil in the area our understanding of the fossil record tells us they should be
Instead, the fossil record shows animals complete -- not in developmental stages -- the very first time they are seen. And this is just what we
would expect if the Bible is right and God created animals whole.
of course theya re complete, they are complete for thier species which is a
transitional for the next
if they wernt complete they would die and be unable to form a transition, lack of knowledge on evolutionary thoery is showing here
so lets look at some of the transitional species we supposedly havnt found
so this is up to tetrapods
but this guys JUST has a P.HD. in chemical biology, better find an expert ... palentology to the rescue
