This little toolkit looks designed for horizontal gene transport (HGT), but there wasn’t anything similar to it for eukaryotes. Then came this article. And apparently humans (a rather sophisticated eukaryote) have circular DNA as well, it just was overlooked for 30 years.
Researchers: “It was previously thought that the only genes that could spread through a population were those that caused a benefit ‘right now’ (in the environment that the population is experiencing at that point in time).” That’s Darwinism. And Darwinism is becoming comprehensively out of date.
At New Scientist: “‘Yeast and bacteria have fundamentally different ways of turning DNA into protein, and this seemed like a really, really strange phenomenon,’ he says.” They ain’t seen nothing yet. If you subtract the “random mutation” from “natural selection,” what’s left of Darwinism? By the time the Raging Woke hammer down Darwin’s statue, chances are the New Scientist crowd will have forgotten who the old Brit toff even was. Shrug.
Paper: “Horizontal gene transfer and mating between diverged lineages blur species boundaries and challenge the reconstruction of evolutionary histories of species and their genomes.”
A friend writes to ask, “If we don’t have common descent, and we don’t have natural selection, why do we still call it evolution?”
Here, in human mitochondrial DNA — note the BLUE code start and the RED code stop; all HT to Wiki publishing against known ideological interest: Complex interwoven code is of course doubly functionally specific, so it is exponentially harder to account for, other than by exceedingly sophisticated and creative intelligently directed configuration. Indeed, when I Read More…
One wonders how much of their genome they steal from more closely related species (as opposed to schoolbook Darwinian evolution).
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.
The selfish gene is an entity driven by an unadmitted teleological force to replicate itself in offspring. But horizontal gene transfer—hardly taken seriously the day before yesterday—features genes that simply end up on a different string. Is a relentless force of selfishness driving them to do that? Or do they just drift and end up on that string?
This explanation makes explicit that this is not Darwinian evolution. One writeup even alludes to the type of Darwinian tale that is being replaced.
Hedging, yes, But there was a time we would have been told about Darwinism. Period.
Wait. What does this story remind us of? Oh yes, recently a writer at The Atlantic went so far as to express doubt about the claim of a Darwin-in-the-schools lobbyist that everyone needs to buy into their approach to evolution if we want to understand superbugs.
Relevant in more ways than one. Remember that recent Atlantic article where the writer was grousing that her school didn’t teach “evolution” (Darwinism)? And a Darwin lobbyist told her that as a result we wouldn’t understand superbugs? Darwinism is probably in the way, actually.
Yes,but what hope is there that textbooks could start teaching reality when even the right to question the Darwinian [sheet] is still a big controversy in many places? Could science writers like Jabr and others agree that it is time to make textbooks about evolution sound like the reality and not like the 1925 Monkey Trial revisited?
Indeed, HGT may well be “the tip of the iceberg,” as the researcher says. Consider: Darwinism is about ancestor-descendant relationships. Take that away and the whole elaborate catechism of altruism, kin selection, costly fitness, etc. is poof! And horizontal gene transfer does indeed take that away.
Does anyone remember when antibiotic resistance was proof of Darwinism? Antibiotic resistance was Evolution. And Evolution was not non-Darwinian stuff like horizontal gene transfer/jumping genes. Welcome to post-Darwin science.
