Why OBSERVED change in organisms is not evolution?

Reasons for organismal change and why it doesn't result in evolution


Most people consider the theory of evolution as fact. This is because people are not taught serious science. Instead, even small children are indoctrinated with pseudoscientific fairytales. Today, evolution is a synonym for change. Let's have a closer look at organismal change and the reasons behind it.

1. Adaptive radiation

A common definition: "Adaptive radiation refers to the adaptation (via genetic mutation) of an organism which enables it to successfully spread, or radiate, into other environments. Adaptive radiation leads to speciation and is only used to describe living organisms. Adaptive radiation can be opportunistic or forced through changes to natural habitats."

This is WRONG! Why?

Serious science: Epigenetic mechanisms and factors help organisms adapt to changing environment. This might result in changes in phenotypes that may inspire biologists to name new species. No novel information arises. The most significant mechanism behind protein diversity and speciation is alternative splicing. No evolution.

An example. Darwin's Finches.

"In contrast, we did find dramatic epigenetic differences between the urban and rural populations of both species, based on DNA methylation analysis."

2. Allopatric, peripatric, sympatric and parapatric speciation. 

These are man-made definitions for phenomena occurring due to different environmental and living conditions. For example, different nutrition results in changes in sex pheromone production and this leads to so-called reproductive isolation. Mate preferences (sexual selection) are driven by changes in certain olfactory receptors. The most significant mechanism behind modifications in olfactory receptors is alternative splicing which is regulated by epigenetic mechanisms and factors. No evolution. An example:

"We also found evidence of some genes showing differential expression or alternative splicing, which may be associated with odorant-sensing between sexes. Most chemosensory receptor genes showed evidence of expression in the zebrafish olfactory epithelium, with a higher expression level in males than in females. Taken together, our results provide a comprehensive catalog of the genes mediating olfactory perception and pheromone-evoked behavior in fishes."

3. Chromosome fusions

The GC --> AT mutation bias results in a reduced level of GC content in all kinds of organisms. So-called Common Fragile Sites are AT-rich chromosomal regions (they contain a lot of Adenine-Thymine pairs due to harmful mutations). In meiotic recombination, DNA is rearranged by complex rules mediated by histone epigenetic markers. The cell tries to maintain a necessary level of GC content (Guanine-Cytosine pairs). In this process, chromosomes are occasionally fused. Chromosome fusions point to genetic entropy. No evolution.

Summary and conclusions:
  • Speciation is a man-made word.
  • Adaptive radiation means epigenetic modifications. No evolution.
  • Allopatric, peripatric, sympatric, and parapatric speciation are due to epigenetic changes in pheromone production or olfactory receptors. The most significant mechanisms behind these alterations are alternative splicing and RNA editing.
  • Bringing different 'species' into the same environment (such as a zoo) often breaks these reproductive barriers especially when animals are fed with similar food.
  • Chromosome fusions are due to mutational load and they always result in loss of biological information.
  • Speciation is like dog breeding; the more adaptation and variation, the more information loss and genetic entropy.
  • There is no mechanism for evolution.
