Creation Moment 8/3/2023 - Lesson from the Cornfield

In the beginning God created.... Genesis 1:1
 In the article below, from a secular site, one can see that TE's are proof of DESIGN for functionability...and the ability to produce different shapes, sizes and colors. The reason it is a problem for evolution is because it undermines random glitches/changes which undermine the core of neo-darwinism and Richard Dawkins....All this change is DIRECTED, for different shapes, sizes and colors for the blooming rose of creation WITHIN each kind....which stays it's kind.
 
"During the past century, discoveries that have challenged the gradualist view of evolution have been sidelined, forgotten, and derided. 
This includes the work of 20th-century geneticists such as Hugo de Vries, one of the rediscoverers of Mendelian genetics and the man who gave us the term ‘mutation’, or Richard Goldschmidt, who distinguished between microevolution (change within a species) and macroevolution (changes leading to new species). 
 
Barbara McClintock, one of the giants of 20th-century genetics, has
not been accepted as posing a viable alternative to dominant theories of evolution.
McClintock won the Nobel Prize in 1983 for her discovery during the 1940s of rapid genetic changes in maize plants that were definitely not random. 
 
In 1944, McClintock began mating maize plants with genomes configured so that both parental pollen and ovule cells contained broken chromosomes. The result of these experiments created what has been described as ‘a genetic earthquake’ in the fertilized embryos. Many could not produce viable maize plants, and those that could grow to maturity often exhibited variegated patterns of coloration in the stalks, leaves and kernels.
 
McClintock found that unstable loci carried insertions of genetic
material that were unlike any previously discovered. She demonstrated that
these ‘controlling elements’, as she came to call them, had previously been dormant in the maize genome and were activated in response to ‘genome shock’ from ongoing cycles of chromosome breakage and repair. 
 
This discovery revealed an entirely new mechanism of genetic
regulation and variability
: maize plants were rapidly changing their own genomes through transposable controlling elements (TEs). And moreover, TE changes were nonrandom in two ways. 
Firstly, the same DNA element could insert repeatedly at new target sites; and, 
secondly, TE mobility and mutagenic activity was activated by specific organismal stress conditions.
 
There are multiple types of TEs, including purely DNA-based ‘transposons’ as well as two different types of ‘retrotransposons’, which use RNA intermediates to move to new locations in the genome.We might expect that McClintock’s discovery of TEs and their rediscovery across all forms of life would have unleashed
serious questions for established views of evolutionary change. 
Instead, her findings were ignored. My own belief is that the reason for this wilful neglect lies in the basic philosophical foundations of mainstream thinking about evolution, which requires a purely physical explanation for all evolutionary processes
 
The fact that TEs respond to stress indicates that they are regulated biological entities that play a sensory-guided role in survival and reproduction. The notion of controlled biological processes at the core of organic evolution is plainly incompatible with a purely physicalist explanation, such as random mutations plus natural selection."
