A Tunable Mechanism Determines the Duration of the Transgenerational Adaptations
Tuning the Duration of Directed Adaptations
Organisms adapt to environmental challenges. In fact, many different organisms adapt in non-homologous ways to many different, unforeseen, environments. This contradicts evolution. For we are not talking about random changes occurring by chance, occasionally getting luck enough to confer an adaptation, and then propagating throughout the population. We’re not talking about an evolutionary process of random mutations and natural selection. That would take a long time. What we’re talking about are adaptations that specifically address environmental challenges, and occur in a good fraction of the population, over a few generations, or perhaps within a generation. Such directed adaptation occurs quickly.
That contradicts evolution because random mutations are not going to create such a complicated adaptation capability. Furthermore, they are not going to do this over and over, in so many different species, for so many different environments. And even if, by some miracle, this did occur, it would not be selected. That is because the adaptation capability is not for the current environment the organism faces, but for an unforeseen, hypothetical, future environment. The moment it arises, the adaptation capability is of no use, and would not be selected for.
But that’s not all.
As with Lamarck’s inheritance of acquired characteristics, these rapid, directed, adaptations are transgenerational. From parent to offspring, the progeny inherit the adaptation from the progenitor.
So now we must not only believe that evolution’s random mutations constructed these unbelievably detailed, complicated, unique adaptation capabilities, but that evolution also constructed the incredibly complicated means to transmit the adaptations to the next generation. As we saw recently, new research has demonstrated such transgenerational inheritance to be genetic, rather than via the parent’s behavior, breast milk, etc.
So again, random mutations must have created yet another complex design (the ability to pass along adaptations for an unforeseen environmental challenge), and it would have been worthless until that particular environmental challenge arose.
But that’s not all.
New research out of Tel Aviv University explains how these acquired adaptations persist through the later generations. Previously, these inherited adaptations were assumed simply to decay or “peter out” over a few generations. But the new research has uncovered proteins that manage and govern the duration of the adaptations. The adaptations are transmitted by small RNA molecules, and the proteins provide a tunable mechanism to govern the duration of the adaptation, over the generations. As the title of the paper explains:
A Tunable Mechanism Determines the Duration of the Transgenerational Small RNA Inheritance
Again, random mutations are not capable of producing such designs, and the designs would not be selected for. None of this makes any sense on evolution.
So now we must not only believe that evolution’s random mutations constructed these adaptation capabilities, and the means to transmit them to later generations, but also to control precisely their duration.
The science contradicts evolution.
