A Brain Emerged for Such a Worm as I
With no room for discussion or Q&A, a press release from European Molecular Biology Laboratory asserted, “Modern brains have an ancient core.” How ancient? At least as far back as the marine ragworm. Continuing the confident assertions, it went on to say, “Multifunctional neurons that sense the environment and release hormones are the evolutionary basis of our brains.”
The article says that neurons in this centipede-resembling annelid worm secrete hormones. This was the basis of a surprising discovery for evolution:
Hormones control growth, metabolism, reproduction and many other important biological processes. In humans, and all other vertebrates, the chemical signals are produced by specialised brain centres such as the hypothalamus and secreted into the blood stream that distributes them around the body. Researchers from the European Molecular Biology Laboratory [EMBL] now reveal that the hypothalamus and its hormones are not purely vertebrate inventions, but have their evolutionary roots in marine, worm-like ancestors. In this week’s issue of the journal Cell they report that hormone-secreting brain centres are much older than expected and likely evolved from multifunctional cells of the last common ancestor of vertebrates, flies and worms.
So rather than being a problem for evolutionary theory, these hormones showed that evolution was an innovator earlier than expected:
“This suggested that hormone-secreting brain centres have arisen after the evolution of vertebrates and invertebrates had split,” says Detlev Arendt, whose group studies development and evolution of the brain at EMBL. “But then vertebrate-type hormones were found in annelid worms and molluscs, indicating that these centres might be much older than expected.”
Of all things. They found that a fish, a vertebrate, and an annelid worm all had hormone-secreting neurons with “stunning similarities.” The similarities between two fish and worm hormones “are so big that they are difficult to explain by coincidence,” the article claimed, seeing evolution as the only alternative. “Instead they indicate a common evolutionary origin of the cells.”
But why would a worm need advanced brain cells? The original paper in Cell,1 speaking of the neurosecretary control centers in higher animals, admitted that “The evolutionary origin of these centers is largely unknown.” A story was forthcoming:
The EMBL scientists now assume that such multifunctional sensory neurons are among the most ancient neuron types. Their role was likely to directly convey sensory cues from the ancient marine environment to changes in the animal’s body. Over time these autonomous cells might have clustered together and specialised forming complex brain centres like the vertebrate hypothalamus.
And how did cells accomplish that, without being able to think or plan ahead? That question was not addressed. Instead, anything “conserved” is obviously “thus phylogenetically ancient,” they said. “At the end of this process, complex brain centers emerged, such as the vertebrate hypothalamus, that integrate multiple sensory input,” obviously.
The team relished in how their findings “revolutionise the way we see the brain.” It’s no longer just a computer with I/O. “Now we know that the brain is itself a sensory organ and has been so since very ancient times.”

Whenever you hear evolutionists saying, “Now we know,” you know two things: (1) they didn’t know anything before, and (2) they’re lying. Now we know is code that a new just-so dime novel has hit the bookshelves, to replace the last one that got exposed as a fraud (e.g., 06/29/2007).
It gets so tiring to watch the Darwinians trying to pull these stunts on us. They are hardened criminals at calling black white and white black. They call creationists the evil ones for engaging in religion instead of empiricism, but then they turn around and grab the bullets nature aims at them, melt them down, and mold graven images to lay at Charlie Buddha’s feet.
Here they found a complex system in a worm and drew an absurd extrapolation, connecting it all the way to the human brain. It should have been a problem that this feature existed long before vertebrates in their timeline, but no! They leapt off the logical cliff and dived into the ocean of evolutionary speculation, where needs cause innovative solutions to “arise.” Without a thinker to think, cells “clustered together and specialized,” all by themselves. Presto: the vertebrate hypothalamus, controlling growth, metabolism and reproduction. Wouldn’t Lamarck and the orthogenesis sect be proud.
It’s becoming a pattern for the evolutionists to find the roots of complex structures further and further back in their timeline. At this rate, it won’t be long before they’ll be claiming that bedrock was the Last Universal Common Ancestor, and that the DNA code emerged in the primordial solar nebula.
Evolutionists can’t continue this line of explanation indefinitely. It puts pressure for all the innovation to occur up front, and leaves less need for change afterward. Why not go all the way, then? Why not agree with the creationists that all the innovation appeared abruptly in the beginning? What’s the problem? We all believe in miracles anyway. Whenever Darwinists need a miracle, they just wave their hands and say such and such a complex system simply “emerged.” Why stretch out the inevitable? Just cram all the miracles together at the beginning, say all the animals and plants appeared fully formed, and be done with it. We’ll even give them six days.
