Die artikel Bird breathing anatomy breaks dino-to-bird dogma is uitstekend. Dit is duidelik dat evolusioniste nie eers naastenby ’n hipotese1 het oor hoe voëls geëvolueer het nie. Ek noem slegs die belangrikste hieronder (LW: die aanhalings hieronder is nie deur skeppingsleerders gemaak nie, maar evolusioniste):

  • …they believe that birds evolved from the carnivorous dinosaur group known as theropods. Yet there are many problems with this idea. And now, new research into the birds’ lung and leg anatomy provides more strong evidence against it.
  • “The idea of feathered dinosaurs and the theropod origin of birds is being actively promulgated by a cadre of zealous scientists acting in concert with certain editors at Nature and National Geographic who themselves have become outspoken and highly biased proselytizers of the faith.”
  • Dr Alan Feduccia (evolusionis): “It’s biophysically impossible to evolve flight from such large bipeds with foreshortened forelimbs and heavy, balancing tails,’ exactly the wrong anatomy for flight.”
  • So the ‘earliest’ bird had the through-flow avian lung system, while one of its closest ‘ancestors’ had a reptilian bellows lung. The transitional forms are lacking.
  • Dr John Ruben – respiratory physiology expert at Oregon State University in Corvallis:
    • “bellowslike lungs could not have evolved into the high-performance lungs of modern birds.”
    • “how would the ‘bellows’-style lungs of reptiles evolve gradually into avian lungs? The hypothetical intermediate stages could not conceivably function properly, meaning the poor animal would be unable to breathe.”
  • …fixed femur and the accompanying muscles and hip bones were essential for the bird to keep its air-sac lung from collapsing inwards when the bird inhales. Devon Quick (John Ruben se kollega) “This is fundamental to bird physiology. It’s really strange that no one realized this before. The position of the thigh bone and muscles in birds is critical to their lung function, which in turn is what gives them enough lung capacity for flight.”
  • Politiek:
    • Ruben: “Frankly, there’s a lot of museum politics involved in this, a lot of careers committed to a particular point of view even if new scientific evidence raises questions.”
    • “…many museum displays treat the dino-to-bird theory as fact… The only nod to dissent might be an asterisk with some fine print saying, “some scientists disagree.””, “But now there are more asterisks all the time. That’s part of the process of science.”
  • Most scientists believe in evolution not because of the evidence, but because most scientists believe it.

 

Voetnotas:

1. Hipotese:

Volgens die HAT is die verskil tussen ‘n hipotese en teorie die volgende:

Hipotese: Ongegronde veronderstelling wat gebruik word om iets anders te bewys.

Teorie: Grondreëlsvan ‘n wetenskap om waargenome feite of verskynsels te verklaar. Geldige teorieë is bv. die atoomteorie, Newton se teorie van gravitasie en Einstein se teorie van relatiwiteit.

Evolusie kan nie ’n teorie genoem word nie omdat dit nie bewys en getoets is/kan word nie.

Kyk ook Arguments we think creationists should NOT use:

What people usually mean when they say “Evolution is just a theory” is ‘Evolution is not proven fact, so it should not be promoted dogmatically.’ Therefore people should say that. The problem with using the word ‘theory’ in this case is that scientists use it to mean a well-substantiated explanation of data. This includes well-known ones such as Einstein’s Theory of Relativity and Newton’s Theory of Gravity, and lesser-known ones such as the Debye–Hückel Theory of electrolyte solutions and the Deryagin–Landau/Verwey–Overbeek (DLVO) theory of the stability of lyophobic sols, etc. It would be better to say that particles-to-people evolution is an unsubstantiated hypothesis or conjecture.

 

Is die skepping-evolusie kwessie belangrik?
