For all practical purposes, the coelacanth is a “living fossil,” in the sense that it is an example of stasis. It wanders a bit genetically over millions of years but doesn’t change much over hundreds of millions of years. Could we say the same of most vertebrates?
At the Smithsonian: Surviving crocodiles did not change throughout millions of years because they arrived at an equilibrium where they were efficient and versatile enough that they did not need to evolve to exist, reports the Conversation.
“55 Million years of separation on different continents is a very long evolutionary path to travel. I would have expected some mix of general similarity and characteristic differences between species in these neural modules. But the fact of the matter simply is: It is practically impossible to tell them apart.” … It sounds a lot like a designed system. The basic core of the hardware and software hasn’t changed in 55 million years.
Cross sections of tusks provide evidence of periods of growth, stress, and activity.
She does a good job of pointing out how much of the history of life is really stasis. But then what about Darwin’s claim about nature daily, hourly adding stuff up, subtracting the bad, retaining the good… Apparently not.
Note that we are told that the find “helps track the evolution of eyes and vision in arthropods over time” but in this case, it appears that their wasn’t much evolution: They “developed apposition compound eyes during the earliest evolutionary stages of the group and stuck with this design throughout their history.” No matter the history, Darwin must be placated.
In the words of one researcher, “Our concept of how cells evolve goes out the window for this incredibly large biosphere.” And yet, we are told, “these almost-but-not-quite-dead cells play an important role in the production of methane, the degradation of the planet’s largest pool of organic carbon, and other processes.”
At Nature: The genome produced by Gemmell and co-workers is one of the largest vertebrate genomes published so far. At more than 5 gigabases, it is about 50% larger than the human genome… Tuatara have a close resemblance to their forebears from the early Mesozoic era, between 240 million and 230 million years ago…
ScienceDaily: Morono was initially taken aback by the results. “At first I was skeptical, but we found that up to 99.1% of the microbes in sediment deposited 101.5 million years ago were still alive and were ready to eat,” he said.
Will we all meet up at the Big Bang? Don’t rule it out.
Like any real history, evolution is not driven by a single force or idea. Horizontal gene transfer from bacteria obviates the quest for an “ancestor” seaweed. Maybe there isn’t one.
But get this: Benson goes on to explain that one of the “bizarre” features of Oculudentavis is qualities present in lizards but neither in birds nor in dinosaurs. It is smaller than most hummingbirds but had over a hundred teeth… The more research we do, one suspects, the more of this type of thing we’ll find and the harder it would all be to explain to our old Darwinian schoolteacher.
It’s not “land” vs. “sea” that’s really significant here. It’s how much time was available for the development of photosynthesis. If the claim is that photosynthesis developed via natural selection acting on random mutations (Darwinism), then it must have somehow randomly happened in that billion years. Was there enough time? becomes an unavoidable question.
It doesn’t sound as though they bothered with much evolution. How would we distinguish their origin from creation? At a certain point, does evolution become creation? Just wondering.
One wants to ask, how distinct ARE the genomes of these species that all look the same?
Would it be like mapping a cat’s genome and finding a German Shepherd’s GATTACA in there? What that level of distinction really tells us goes well beyond cats and German Shepherds. Or do the researchers really mean something less highly distinct? What? We search for analogies here.
