Neutrons Explain How Haemoglobin Evolution in Red Blood Cells Helped the Duck-Billed Platypus Respire

Posted June 21, 2012 10:28 AM

From Phys.org - latest science and technology news stories:

Scientists have explained the evolutionary history of haemoglobin using what might seem an unlikely array of samples. Researchers focused the world's most intense neutrons beams on the oxygen-carrying protein from a human, a duck-billed platypus, a chicken and a salt-water crocodile to explain how it has adapted to different body temperatures within different species. The results of research at the Institut Laue-Langevin (ILL), Aachen University of Applied Sciences (FH Aachen), the Australian Nuclear Science and Technology Organisation, the Centre National de la Recherche Scientifique (CNRS) in Paris and the FRMII facility in Germany could lead to interesting developments in bio-engineering and biomedical research.

Maybe a small detail but a question that has to be asked. How did the species itself survive for tens of thousands of years before this "trait" evolved? If the trait was needed for survival, the species would have become extinct before it "evolved" to a higher, more advanced species with all the necessary qualities and characteristics.

Have evolutionists ever stopped to think how far and illogical they have to stretch to make that unproven theory work? I'm certainly not saying there aren't unanswered questions about Creation either but that is an element of faith not stretched logic.

There is change within species to adapt to environment but there has never been change between species types.

I'll go back to my "coloring book" now.

My wild theory on this would be that the species could survive with a lower oxygen content in the haemoglobin, but it would not operate as efficiently as it would once the haemoglobin evolved to it's optimum condition. (ie. lower energy, more anemic) The ones within the species that had a closer to optimum haemoglobin configuration would have more energy and would have a better chance of surviving, which would push the evolution of that particular haemoglobin structure. Rinse & repeat over tens of thousands of years.
