Fish May Be Evolving To Swim Faster- Not!

As much as the evolutionist might wish for you to believe, this is not an example of evolution:

“Fish may be evolving to swim faster to escape capture by fishing nets from trawlers, according to research. A study by the University of Glasgow has shown that fast­swimming fish are less likely to be trapped by fishing nets and that over time this could lead to physiological changes in fish populations. The university group simulated trawling with schools of wild minnows to determine whether some individual fish were consistently more susceptible to capture, and measured the swimming ability, metabolic rate and indicators of aerobic and anaerobic physical fitness of 43 fish.”   Faster fish may be evolving to give trawler nets the slip

It is, of course, an example of natural selection, but not of evolution.  The slower fish are removed from the gene pool leaving the faster fish to breed and produce offspring, and if that characteristic is passed on it will result in faster fish in the sea.

But how does that differ from a dog breeder picking dogs for speed to breed resulting in the greyhound?  Both the faster fish and faster dog are the results of the intervention of humans, and neither have lead to a new species!

And God made the beast of the earth after his kind, and cattle after their kind, and every thing that creepeth upon the earth after his kind: and God saw that it was good. Genesis 1:25
