Mutations guided by national selection have become one of the most if not thee most important aspect in evolution. Growing up, I was taught that evolutionary adaptation was the result of experience. National Geographic had programs on advocating the experience of one animal would produce an advantage or certain new features over many generations.
As science grew, it became apparent that the hypothesis was falsified. There is no link between one’s experience and their reproductive cells. No wire link, no strand, no signals of communication between the two whatsoever.
So evolutionary scientists altered the hypothesis, focusing in on mutation with natural selection rather than natural selection on it’s own…It’s basically their last stand on how things could have evolved biologically. There is no other explanation in the belief of naturalism which can be found.
In the years of scientific research we see that mutations produces three changes in genes or chromosomes. And they listed below…
1) an alteration of DNA letter sequence in the genes
2) gross changes in chromosomes (inversion, translocation)
3) a change in the number of chromosomes (polyploidy, haploidy).
But whatever the cause, the result is a change in genetic information…Now in order for mutations to be successful in observing evolution (directly or indirect) the following needs to happen.
1) Millions of specific purposeful changes which are dramatic enough for the species to change into another.
2) Increased information
We know that most (not all) small changes caused by mutations results in harmful effects which results in disease and even death as also pointed out by this known evolutionist…
“A proportion of favorable mutations of one in a thousand does not sound much, but is probably generous, since so many mutations are lethal, preventing the organism from living at all, and the great majority of the rest throw the machinery slightly out of gear.”
—Julian Huxley, Evolution in Action, p. 41.
This brings me to the next point, mutations happen on a rare basis. There has been much debate over the math aspect, which entails many assumptions. It’s been estimated that mutations are created in one in ten thousand and one in a million per gene per generation. It’s lower in the smaller organisms. Evolution requires millions of changes in order for it to be successful, yet it’s a very rare event.
Now mutations need to specify their work in order to make changes which leads to other species. Random chaos, wouldn’t accomplish such a feat. Just creating numerous mutations which function with no purpose but instead just be chaotic in the body would lack the ability to have a profound effect leading to change. Even the smallest animal is complex which would require specified changes.
And lastly, since mutations are “copied information” it doesn’t create any increase of information from scratch and a progression of a new enhanced features. It may change certain features but what advantage it does create is only limited in a certain area. In cases like digesting milk where it has been observed loosing it’s advantage in the adulthood stages rather than maintaining or enhancing it’s function.
The vital importance of mutations and information is evolution’s last stand, there is no other. It’s not on solid ground and lacks scientific evidence (not explanations) in order to be successful. In other words, evolution’s last stand has fallen.
