Evolution vs. Intelligent Design

17.04.2008
There is heated debate taking place over whether organisms are the result of intelligent design or evolution.

The proponents of intelligent design believe that chance and selection are too casual and slow to allow complex new properties to arise. In particular, they argue that the intermediate steps in shuffling the genes to make something new are likely to scramble the existing system and be bad for the organism ("half an eye is bad for you").

The work, directed by Mark Isalan, leader of the group Gene Network Engineering and Luis Serrano, coordinator of the research programme Systems Biology and leader of the group Design of Biological Systems, from the Centre for Genomic Regulation in Barcelona, Spain, will be published tomorrow in the prestigious magazine Nature.

Although it’s true that it seems incredible that organisms could be able to face extreme mutation processes and gene reorganization, Isalan et al. show just that. This work describes a new method that links information networks in the genome of the bacterium Escherichia coli that are not usually communicating with each other. Not only do most of the bacteria survive with the new transcription networks, but some gain new properties that allow them to do better than the original bacteria in extreme conditions. For example, some survive better at 50°C or have a longer lifespan after growing to maturity.

Organisms appear to have an innate capacity to allow evolution. This new and revolutionary methodology opens the door to a much more rapid evolution that offers multiple new phenotypes or properties.

This will have useful applications in biotechnology, for example in the production of biofuel from more efficient microorgansims. Ultimately, evolving cellular gene networks may allow the production of new properties in a wide variety of cells, with profound implications for human health.

Im Focus: Future electronic components to be printed like newspapers

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.

The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
