To make a comb jelly engaging to a Darwinist, all you must do
is cut back by 1 the variety of miracles required for its sudden look
Comb jellies (phylum Ctenophora) are fascinating little creatures within the ocean. They’re not associated to jellyfish (phylum Cnidaria). As an alternative, they’ve comb rows alongside their clear bells with tiny bundles of cilia that refract gentle as they beat, creating touring waves of coloration that give them the looks of little spaceships (see YouTube video). They’re advanced creatures with a intestine, motility and a nervous system. Like many different animal phyla, they make their first look immediately within the Cambrian fossil file, a part of Darwin’s dilemma referred to as the Cambrian explosion.
Evolutionists have been worrying for years about the place to suit comb jellies into their imaginary tree of life. Primarily based on molecular comparisons, some have thought they may have been among the many first multicellular animals. Different Darwinians have thought that concept far too inconceivable; they’ve tried to make sponges first, as a result of they give the impression of being a lot easier to the attention (however see Evolution Information about sponge complexity).
One other research within the lengthy collection of speculations about comb jellies pretends to make headway on the query. Darwinians really feel they’re making progress if they’ll subtract one miracle from the collection of miracles required to clarify any advanced animal. On this case, evolutionists on the Okinawa Institute of Science and Know-how declare they’ll cast off the notion that neurons advanced twice independently. One miraculous sudden look of neurons will do. Whew!

Into the mind of comb jellies: scientists discover the evolution of neurons (Okinawa Institute of Science and Know-how, 9 August 2022).
Sure, the Darwin Social gathering has an iron grip on science in Japan, too. They seized management a very long time in the past. As in America and Europe, there isn’t a tolerance for creationism there, or clever design, both. Comb jellies? They exist; subsequently they advanced! That’s all a scholar must know in science class.
Some professors, although, wish to know when they advanced within the lengthy chain of progress from molecules to man. And that query just isn’t so easy.
Regardless of their supposed simplicity, little or no is thought concerning the nervous system of historic animals. Out of the 4 animal lineages that branched off earlier than the rise of extra advanced animals, solely comb jellies (the primary historic lineage to diverge) and cnidarians (the final historic lineage to diverge) are identified to own neurons. However the uniqueness of the comb jellies nervous system in comparison with that seen in cnidarians and extra advanced animals, and the absence of neurons within the two lineages that diverged in between, led some scientists to hypothesize that neurons advanced twice.
A diagram reveals 4 phyla lined up. Two of them (ctenophora and cnidaria) have neurons. The opposite two (porifera, or sponges, and placozoa) should not have neurons. To Darwinians, solely two explanations exist to maintain Darwin’s notion of common frequent ancestry intact. The caption reads,
How neurons first advanced is a long-standing debate. Some scientists consider that neurons advanced as soon as and was then misplaced in some animal lineages (origin factors proven in inexperienced). Others consider that they advanced twice, one time within the lineage that led to the rise of comb jellies, and a second time within the lineage that led to cnidarians and extra advanced animals….
Why invoke two miracles when one will do? Professor Hiroshi Watanabe, who leads the Evolutionary Neurobiology Unit on the Okinawa Institute of Science and Know-how (OIST), carried out divination on genes for neurons within the 4 teams. His conclusion? The phyla missing neurons should have misplaced them. Neurons should have solely advanced as soon as within the frequent ancestor of the 4 teams.
“We already know that cnidarian peptide-expressing neurons are homologous to these seen in additional advanced animals. Now, comb jelly neurons have additionally been discovered to have the same “genetic signature”, suggesting that these neurons share the identical evolutionary origin,” mentioned Prof. Watanabe. “In different phrases, it’s probably that neurons solely advanced as soon as.”
To the nice reduction of the Darwin Social gathering, Watanabe’s clarification solely requires one miracle. Or does it?
Practical Complexity Doesn’t Simply Occur
Neurons are extremely advanced cells with beautiful channels that may selectively transmit sodium or potassium ions at excessive pace towards the focus gradient. In his current guide The Miracle of Man (Discovery Institute, 2022), molecular biologist Dr Michael Denton describes how these channels function in human neurons:
One other aspect of prior health is the existence of small cellular ions—together with sodium (Na) and potassium (Okay), that are ideally suited to maneuver electrical cost at nice pace by diffusing quickly down electrochemical gradients via the lipid bilayer through extremely selective ion pores—known as ion channels or gates. What makes sodium and potassium very best for this work is that they bind solely weakly to natural compounds, rendering their mobility excessive. Certainly, their mobility and capability to maneuver quickly down gradients via ionic channels is astounding. As Bruce Alberts [Harvard biochemist and former editor of Science Magazine] and his colleagues observe, “As much as 100 million ions could cross via one open channel every second.” (P. 161.)
These ions, bear in mind, don’t merely diffuse by osmosis. They must be pumped in or out of the cell membrane towards the focus gradient. However that solely begins the surprise of nervous system operation. Neuronal cells possess 1000’s of those channels, and as they open to ions, waves of cost cross down the size of the neuron quickly and proceed throughout synapses to the following neuron. In people, a sign can cross from toe to move in a fraction of a second. Alberts says in his textbook Molecular Biology of the Cell that “Single Neurons Are Complicated Computation Gadgets.”
Comb jellies (Ctenophora) are very advanced animals to have appeared abruptly. (DFC)
Comb jellies, being smaller, can reply with a bit much less complexity, however even then, a single neuron with its ion channels is irreducibly advanced. It might be extremely simplistic to think about such a system of working neurons to “evolve” by miraculous emergence even as soon as, not to mention twice. If counting miracles, then, accounting for a single origin within the ancestor of 4 phyla as an alternative of twin origins just isn’t chopping the variety of pure miracles in half; it’s like subtracting one miracle from 1000’s.
No Assist in the Paper
Watanabe’s answer is revealed August 8 in Nature Ecology & Evolution with the title, “Mass spectrometry of brief peptides reveals frequent options of metazoan peptidergic neurons” (Hayakawa et al., open entry). It begins with the unhelpful (for Darwin) sentence, “The evolutionary origins of neurons stay unknown.” After all, it’s not unknown to creationists who see neurons as merchandise of clever design. However the ignorance continues within the Foremost part: “Understanding the origins of neurons stays one of the crucial intractable challenges in evolutionary biology.”
A comparability of genetic traits revealed that the peptide-expressing cells of Cnidaria and Ctenophora specific the overwhelming majority of genes which have pivotal roles in maturation, secretion and degradation of neuropeptides in Bilateria [which includes humans]. Practical evaluation of neuropeptides and prediction of receptors with machine studying demonstrated peptide regulation of a variety of goal effector cells, together with cells of muscular methods. The placing parallels between the peptidergic neuronal properties of Cnidaria and Bilateria and people of Ctenophora, essentially the most basal neuron-bearing animals, counsel a frequent evolutionary origin of metazoan peptidergic nervous methods.
Nowhere does the paper clarify how advanced neurons might have arisen by Darwin’s Stuff Occurs Regulation. As an alternative, the entire level of the paper is to argue that neurons advanced as soon as as an alternative of twice. However “placing parallels” between the neurons of comb jellies, jellyfish and people might be defined higher by design as an alternative of likelihood evolution—until design has been dominated out of courtroom by Darwin fiat.
Watch the comb jellies in motion on YouTube and ask if these advanced animals, with their stunning lighting results and neurons, simply “appeared” from single cells by evolution. When you agree that such a narrative is very implausible, are you mad but on the Darwin Social gathering for pretending that likelihood is the one scientific clarification, and for censoring anybody who sees proof for design?
To essentially get animated concerning the scenario, contemplate that the Darwinians consider that round 20 totally different physique plans (phyla) together with comb jellies appeared immediately within the Cambrian explosion, with no fossil ancestors, and that Darwin himself thought-about this downside one of many predominant objections to his idea (watch the movie Darwin’s Dilemma or learn the guide Darwin’s Doubt).
As if that isn’t insupportable sufficient, the scenario with the Cambrian explosion has solely gotten worse since Darwin, however the Darwinists are nonetheless instructing impressionable college students that the Stuff Occurs Regulation is the one legitimate scientific clarification for all of life, they usually proceed censoring anybody who disagrees with them. This insupportable scenario stretches across the globe all the way in which to Japan. Evolutionary idea offers them quite a few “intractable issues” just like the origin of neurons, however they consider it despite proof and logic. Now you see why Romans 1:18-22 is so pertinent to our instances.
