@Dad1   Explain in your own words the best few reasons/data/evidence points that you actually think your close relative is a little flatworm?

Because that’s where the physical evidence points to.

Plus the fact that the flow of evidence is so harmoniously self-consistent.  But you wouldn’t have a clue what I mean if you never learned anything about genetics and the science of tracing DNA into the dim reached of the past.

@Dad1   I am familiar with the key aspects of origin science claims

Then why haven’t provided any indication of that familiarity.   All you are doing is baiting.   Why do you have a difficulty appreciating the evidence.  I mean don’t you notice that accumulating change over time is about as fundamental as we can get.  Why would what we witness day to days not lead to evolution over the centuries and eons.  Care to respond to that.   Or are you just going to ridicule and never actually engage???

Why don’t you believe a flatworm is a very distant relative of your’s.

{Heck, you can’t even pretend to take any this serious “close relative” – or are you just that awfully ignorant?    I don’t mean ignorant as in stupid, I mean ignorant as in willfully ignoring evidence that is readily available.}

Next you will tell me I do it all on faith.  Sure I have faith that the global community of scientists are dedicated to learning and for the most part honest, and best of all, that all these scientists get their work cross examined by other competitive experts, so seems to me the best humans can do.

Sure better than demanding I believe you or anyone, simply because their ego driven belligerent forcefulness demands no less.  No sir, I’m no trumpkin type.   It’s solid evidence and rational constructive arguments I believe in.

… Shook the evolutionary tree

This used to be the common story between the 1990´s to 2011, when an international team of researchers found that flatworms and humans are not species with a simple common forefather, by new RNA-analysing methods and new ways of setting up experiments.

As a result, the flatworm, for a moment, lost its position as a key species. It was reduced to a deficient creature in terms of evolution, and belongs to the same branch as us humans. The new forefather must have been a much younger and more complex being than the original, the new findings concluded.

These findings, however, led to a lot of scientific doubt, also from Hejnol. He thinks the alternative sequence of evolution is a result of the researchers left out important data in their analysis. And if they where right, the acoel flatworms must have been evolved from a forefather with a central nervous system, gut, mouth and anus.

“If they would have been right we would have lost a very informative group of animals that helps to understand the evolution of organs,” Hejnol argues.

According to Andreas Hejnol, this is not necessary anymore. He claims he has now nailed the flatworms to its original position in the tree of life, once and for all. …

Here’s an oldie but Goldie, that still hold up for the most part.  What can I say, the experts can explain better than the spectators and enthusiasts.

Abstract
The planarian is the simplest living animal having a body plan of bilateral symmetry and cephalization.

The brain of these free-living flatworms is a bilobed structure with a cortex of nerve cells and a core of nerve fibres including some that decussate to form commissures. Special sensory input from chemoreceptors, photoreceptor cells of primitive eyes, and tactile receptors are integrated to provide motor responses of the entire body, and local reflexes.

Many morphological, electrophysiological, and pharmacological features of planarian neurons, as well as synaptic organization, are reminiscent of the vertebrate brain.

Multipolar neurons and dendritic spines are rare in higher invertebrates, but are found in the planarian.

Several neurotransmitter substances identified in the human brain also occur in the planarian nervous system.

The planarian evolved before the divergence of the phylogenetic line leading to vertebrates. This simple worm therefore is suggested as a living example of the early evolution of the vertebrate brain.

An extraordinary plasticity and regenerative capacity, and sensitivity to neurotoxins, provide unique opportunities for studying the reorganization of the nervous system after injury. Study of this simple organism may also contribute to a better understanding of the evolution of the human nervous system.

Look up consilience of evidence sometime.
