"Molecular Evidence Supports Key Tenet Of Darwin's Evolution Theory"



(from http://www.SCIENCEDAILY.com)

"As a model system, the research focused on one specific molecular machine, the TIM complex, which transports proteins into mitochondria. Mitochondria are a compartment of human cells that serve as the energy-producing 'powerhouses'. At a very early stage in evolution, mitochondria were derived from bacteria that lived within the first eukaryotic cells.

'Our cells literally are chimeras of a "host" cell and these intracellular bacteria. Yet bacteria don't have TIM complexes – to understand where the TIM complex came from we simply applied scientific reasoning and looked at a modern-day bacterium akin to the organism that gave rise to mitochondria.' Professor Lithgow said.

The group looked at the bacterium Caulobacter crescentus and found bacterial proteins related to the components of the mitochondrial TIM complex. They then showed that these bacterial proteins are not found as part of protein transport machines.

'Fran├žois Jacob described evolution as a tinkerer, cobbling together proteins of one function to yield more complex machines capable of new functions.' Professor Lithgow said..."

Michael Behe (Biochemist)
The most scientifically credible proponent of Design over Evolution



To find out more about what has been one of the stronger arguments against Darwinian evolution; that being that the molecular structures within cells (especially protein "machines") are too complex and specific to be a product of evolution... click here to read about the earnest but flawed work of Dr. Michael Behe. I think his idea of an "irreducible complexity" of cell structures overlooked the probabilities discussed in the above article...


(click on this image, it's really cool in detail)

...not to mention that the following fields and developments within and across various fields of science point to Darwinian evolution as an accurate description of the state of life on Earth:

1. Geologic Stratigraphy
2. Plate Techtonics
3. Comparative Embryology of Vertebrates
4. We can actually see it at work with some species, like fruit flies.
5. We have done it with selective breeding of domestic animals.
6. The Fossil Record (which goes along with our understanding of rock layers, Stratigraphy)
7. Comparative Anatomy and Physiology
8. Geographical Distribution of animals
9. We also have made recent advances in fields like the evolution of the Terrestrial Atmosphere through time, Paleoclimatology, and Microbial Fossils.

* I was a bit lazy here, and just linked to Wiki articles, but we can spend more time on these 9 items later. :)
