Classic mistake

Classic mistake

It is a classic mistake to confuse change with evolution. We can observe change occurring in nature because organisms effectively adapt to changing conditions. However, why isn't change evolution?

The adaptation of organisms is ALWAYS based on epigenetic mechanisms and factors. Epigenetic modifications are dynamic and reversible because cells use specific mechanisms, such as epigenetic readers, writers, and erasers for epigenetic information. You can learn more about these by searching for 'epigenetic readers, writers and erasers.

Epigenetic regulation inevitably leads to genetic decay because methylated cytosine is 20,000 times more likely to change to thymine than unmethylated cytosine. This inevitably leads to the gradual conversion of the GC content of all organisms' cells into AT content. The cell must maintain at least 38% GC content, so it rearranges DNA during reproduction, in so-called meiotic recombination. This usually reduces the total amount of information.

We can therefore observe rapid epigenetic adaptation of organisms, based on the epigenetic regulation of existing information OR the loss of information and subsequent reorganization of information. However, evolution that crosses species boundaries (kinds) has never occurred.

Methylated cytosine is 20,000 times more prone to turn to thymine.
