Evolution Is Useful

From an article somewhere else,

----
Darwinian evolution, unlike true sciences such as chemistry and physics, cannot be employed to predict anything or to make exact classifications of anything. It is nothing more than a speculative hypothesis with no way to employ normal scientific tests to assess its validity. Believers have nothing to cling to beyond the word of Darwinians that things "could have been" as they hypothesize.

This is just a typical bald-faced lie often told by pseudochristian narcissists. Easily refuted, take a look at this article.

Here's an exceprt.

If Darwin was right, for example, then scientists should be able to perform a neat trick. Using a mathematical formula that emerges from evolutionary theory, they should be able to predict the number of harmful mutations in chimpanzee DNA by knowing the number of mutations in a different species' DNA and the two animals' population sizes.

"That's a very specific prediction," said Eric Lander, a geneticist at the Broad Institute of MIT and Harvard in Cambridge, Mass., and a leader in the chimp project.

Sure enough, when Lander and his colleagues tallied the harmful mutations in the chimp genome, the number fit perfectly into the range that evolutionary theory had predicted.

In a 1995 article in Science, Douglas Futuyma listed several ways that evolutionary biology is being utilized:

* Biodiversity and conservation: Analysis of risk of extinction due to "inbreeding, reduced gene flow, specialization, and constraints on genetic and ecological responses to global change."

* Phenotypic expression in novel environments: Use of tools already in use in studies of natural systems, like "molecular markers of gene flow, gene geneaologies as evidence of gene exchange, analyses of phenotypic plasticity, and the 'costs' of adaptation".

* Novel processes and products: This includes production of antibiotics, flavors, pigments, biopolymers, and enzymes.

* Bioremediation: Production of tolerance to waste products as well as bacterial strains to decompose hazardous materials.

* Wildlife management: Identification of stocks by genetic analysis.

* Agriculture: Identification of disease resistance factors in related wild plants, pesticide resistance, management of pest adaptation to pesticide, pest resistant cultivation.

* Health sciences: Causes of senescence, treatment of fever, tracing origins of pathogens, evolution of virulence in viruses and other pathogens, measurement of genetic diversity in pathogens and hosts, mechanisms of drug resistance, evolutionary epidemiology.
