One of the most fundamental things we learn regarding Darwinism is this...”Evolution is not free to make anything, it makes things that work by gradual steps…That is a finite set of options.” says a blogger in response to a previous post. Nature doesn’t agree!
For example, a Cambrian arthropod that was recently discovered in China, had a complex brain! The imprint was so well-preserved that scientists were able to trace the neural pathways from the brain all the way to the eye stalks! This discovery defies evolutionary thinking of “making things work by gradual steps (from simple to complex).
Evolutionists begin to ask, “why would nature create an advanced brain anatomy with a primitive body plan?” So you have this animal with a very simple body structure with a modern brain! Even though Stausfeld, a neurobiologist at the University of Arizona believes this fossil ‘evolved’ his explanation goes against evolutionary expectations…
“The fossil supports the idea that once a basic brain design had evolved, it changed little over time, he explained. Instead, peripheral components such as the eyes, the antennae and other appendages, sensory organs, etc., underwent great diversification and specialized in different tasks but all plugged into the same basic circuitry.”
“It is remarkable how constant the ground pattern of the nervous system has remained for probably more than 550 million years,” Strausfeld added. “The basic organization of the computational circuitry that deals, say, with smelling, appears to be the same as the one that deals with vision, or mechanical sensation.”
Not only is this fossil falsifying “gradual steps” but has evolutionists suggesting that evolution goes backwards! In the story of evolution, insects evolved from simpler-brained branchiopods.
“Because the brain anatomy of branchiopods is much simpler than that of malacostracans, they have been regarded as the more likely ancestors of the arthropod lineage that would give rise to insects.
However, the discovery of a complex brain anatomy in an otherwise primitive organism such as Fuxianhuia makes this scenario unlikely. “The shape [of the fossilized brain] matches that of a comparable sized modern malacostracan,” the authors write in Nature. They argue the fossil supports the hypothesis that branchiopod brains evolved from a previously complex to a more simple architecture instead of the other way around.”
Stausfeld, a Londoner and two Chinese colleagues their paper in nature admitted to branchiopods under going “evolutionary reduction” in brain structure rather than a step by step increase that is normally expected! Why would such a reduction have to occur, wouldn’t have been better (or more fit) to have the brain remain complex and evolve it more from there?
Does this shed more understanding on how evolutionary expectations don’t work when observing nature, oops I mean work? One hears this a lot when evolution is falsified.
Graham E. Budd says this in nature…
“Even to palaeontologists, the fossil record can resemble the chaotic attic of an eccentric relative, stacked with ancient bric-a-brac of dubious usefulness. But the record has recently been throwing up some surprises that are bringing new order to this jumble. Our concept of dinosaurs, for example, has evolved from what were essentially bolted-together lumps of bone into living creatures covered in graceful feathers — and in colour too. Other fossil finds have brought changes to the scale of our understanding of evolution.”
“For example, the discovery of exceptionally well-preserved fossil muscle fibres throughout the record and fossilized embryos from at least the Cambrian period, some 500 million years ago, have provided remarkable insight into the fine-scale evolution of these tissues and life stages. Now, on page 258 of this issue, Ma and colleagues describe preserved nervous tissue from the Cambrian — a find that grants palaeontologists access to the exclusive zoological club of those who study the brain and nervous system.”
When a “theory” increases in complexity as a result of falsifications which happens a lot in evolution, it doesn’t hold up in explaining the realities of nature! How these complex muscle fibers and embryos from the earliest parts of the record could provide such “insight” into evolution was left unexplained.
The Cambrian shows an abrupt appearance of all the animal body plans along with complex brains but no transitional forms. Transitional forms should out number the species themselves in the fossil record! From there, diversification and simplification occurs according to built-in variability and adaptation mechanisms, but the original complex designs endure! This is my friend what you call, evidence that confirms creationism!
