Bird Evolution – Dinosaurs Not The Solution???
PLEASE READ MILOS BABIC COMMENT BELOW – It gives a different and what I believe now, more accurate viewpoint on the bird-dinosaur debate.
Sometimes, a ‘fact’ comes into human knowledge and, for some unfathomable reason, takes root as a certainty. And few think to dispute it. Take for example the concept that a swan can break your arm. I’ve heard people say this with absolute belief, but come on – a swan breaking a human limb? What does it do, twist its neck around your arm, conduct a clever twisting movement and snappity-snap, one arm broken? Seems a tad difficult to believe.
Hearing is believing
Another piece of information that has been taken up with enthusiasm without any regard for evidence is the idea that birds evolved from dinosaurs. The concept of the ‘dino-bird’ is very popular, not only with the common man, but with much of the bio-scientific community as well. I have to admit, it does sound great, birds evolving from dinosaurs, and I’d love it to be true that our feathered companions were once our dinosaur predecessors, but it is in fact, unproven, and quite likely, totally false.
What, no dino-bird?
The idea that birds evolved from dinosaurs has been around a long time, but was recently promoted due to the ‘discovery’ of a fossil in China called Shenzhouraptor sinensis in 2002 . This fossil depicted a feathered dinosaur dated 140-million years old and was hailed as the missing evolutionary link between dinosaurs and birds. Darwinists have always theorised that scales developed into feathers, hence reptiles (dinosaurs are a descendent of the diapsid reptile) developed into birds, but, as yet, there has been no fossil evidence found to support this theory.
What a great discovery then with the Shenzhouraptor to be able to confirm that those scaly dinosaurs of Jurassic fame have become the birds of the 21st century. Well, it would have been great except for a few important and brushed-aside observations that the evolutionary theorists don’t want to hear.
Why birds aren’t dinosaurs
1) The oldest known bird is the Archaeopteryx and is no different in structure to birds today. It lived 150-million years ago making it older than the Shenzhouraptor sinensis, which therefore means that the Shenzhouraptor sinensis cannot be a transitional form. Also the theropod dinosaurs, deemed the Archaeopteryx‘s ancestor, appear later in the fossil records.
2) Feathers are too complex to have come from scales. As A. H. Brush, professor of physiology and neurobiology, University of Connecticut states, “Every feature from gene structure and organisation, to development, morphogenesis and tissue organisation is different [between feathers and scales].” The protein structure of bird feathers is also quite unique amongst vertebrates. And there are no fossils showing intermediate states of development, feather fossils appeared suddenly with no apparent precursor.
3) Lungs and breathing differ radically between birds and land animals. In land animals, the air is inhaled and exhaled from the same place. In birds, the air follows one direction through the lungs and leaves by a different exit. Evolution between these mechanisms is said to be impossible as a reversal of the lung structure (required to change breathing mechanism) would prove fatal to the evolving creature.
4) Every ‘dino-bird’ fossil put forward in the last ten years has been unproven. Most of their ‘feathers’ have turned out to be collagen fibres (hair). Some fossils even turned out to be fakes, like the Archeoraptor (a generic name for a dino-bird fossil) revealed in 1999 from China, but subsequently found to be made up of pieces of other animal fossils.
Where does this leave us?
Taking all those facts above into consideration, the notion that birds came from dinosaurs doesn’t hold well. Disappointing perhaps as the dinosaur-bird evolution is a great idea, which is probably why so many people believed it (or still do believe it). After all, when you want something to be true, it doesn’t take much for the mind to convince you that it is actually so.
“The human understanding is like a false mirror, which, receiving rays irregularly, distorts and discolours the nature of things by mingling its own nature with it.” [Francis Bacon].
So where do birds come from then? Ah, I can answer that one. No one knows. Not yet anyway. Until then, birds will remain the evolutionary mystery of our time.
