What I said is that the articles themselves are illustrating the contradiction of evolutionary thought with scientific results. The articles are doing this. They do it in the titles, and they do it in the text. The authors of the study are doing this, too. I don't have to, because they are doing it.
That's funny, because I don't see anything in the title, article, or original publication where any of the scientists say anything that resembles "therefore we should reject evolution"
as you claimed.
Let's first note the title. You understand, I'm sure, that the idea of the tree of life is that as organisms propagate, they have offspring that is dissimilar enough to the parent that they can be called a different species. This may take a good number of generations, but eventually the offspring are different enough. As this happens over and over to a particular starting organism, its offspring can continue to diversify. Thus, for any one starting organism (or pair of organisms, if necessary), it's descendants ascend (irony intended) to different and better capabilities. This is illustrated by a single trunk of a "tree" branching out into many branches.
So exactly what in the title do you think should lead one to reject evolution?
What this is saying is that the tree of life concept predicts that species will bring forth other species in a linear fashion--with each branch separately branching off further. But Uppsala researchers have found something that doesn't hold to the simple tree of life concept. They distinguish this new concept by claiming it's more of a "bush of life".
So they find that under
adaptive radiation (a concept that's been in evolutionary biology for about a century), we get evolution and speciation proceeding in a specific manner that produces a more complex "shape".
Exactly how does that translate to "therefore we should reject evolution"?
This paragraph explains how a bunch ("consortium") of scientists mapped out the order of evolution of 50 bird species with respect to one another, including the "exact order" they had diverged in.
Right....so they mapped out
how those species evolved, and according to you that means we should reject evolution?
Two members of the original bunch ("consortium") have looked at the 50 species in another way ("method") which tells a different story ("partially contrasting picture") about how these species are interrelated ("kinship").
So they come up with a more detailed understanding of how these species evolved, therefore we should reject evolution?
Here our buddy Hans says that things didn't go as originally thought ("failed to split into separate lineages"). This is the author of a follow-up study saying the first consensus was really a faulty conclusion.
Yeah, that's how science works. As more data becomes available, you update your models accordingly. As [MENTION=20697]Vulcan Logician[/MENTION] noted, that's a good thing. But for some reason, you creationists keep trying to cast it as a knock against science.
Let's assume for a moment that the consortium's logic was impeccable. That would mean that there was a faulty premise that lead to the faulty conclusion. What was that faulty premise? That life diverges like a tree branching.
Again, more complete data gets incorporated into their model and leads to a better understanding of how these species evolved. And to you that means "therefore we should reject evolution"?
They go on to give their solution to the puzzle--jumping genes. This is an interesting concept that brings to light another failed evolutionary concept, since jumping genes were at one time considered junk DNA. Now they use their conclusion to falsify (if it hadn't already been falsified) the junk DNA status of transposable elements.
Um, no. You've completely misunderstood that. It's specifically because the retrotransposed elements are non-functional that they were able to be used for this analysis. From
the original paper...
Homoplasy via independent RE insertion requires the retrotransposition of the same RE subtype into precisely the same genomic location, in the same orientation, and featuring an identical target site duplication. In addition to these factors that make independent insertions very rare, the LTR retrotransposons studied here have a low copy number (e.g., 3,138 copies in the zebra finch genome), were active only for a short time period around the neoavian radiation [10], and show no target site preference among thousands of reconstructed ancestral target sequences of inserted elements (S2 Fig). We therefore propose that the probability of homoplasy caused by independent insertions among our RE markers is extremely low.
If those REs were functional, the above wouldn't make any sense at all.
Jumping genes are the supposed solution to the conundrum that "for instance, a cuckoo can be more closely related to a hummingbird than a pigeon in a certain part of its genome, while the opposite holds true in another part." In other words, the cuckoo looks like it descended from a hummingbird (or vice versa) if you look at one part of the genome, and from a pigeon (or vice versa) when you look at another part, BECAUSE that's what the genome says! Which can't be if species descend in a linear branching pattern. Thus the authors say the "tree" looks more like a "bush". Jumping genes allow us to consider that species are descended from a single progenitor through a tangled mess of relationships where branches reconnect and divide again.
So again, more complete data produces a more complex picture of bird evolution.
And "transposable elements" go back and forth, thus needing the prefix "retro" added on.
Again, you have this completely wrong. "
Retrotransposons" are genetic parasites that exploit their host's genome by getting it to "copy and paste" the parasite's genome in various places in the host's genome. The "retro" prefix refers to it replicating via the copy-n-paste method, rather than the "cut-n-paste" method of transposons.
Remember that genetics was the savior of Darwin's theory, becoming the foundation of the "modern synthesis" of the theory of evolution. But now, as we see in the article, scientists have to use words like "incomplete lineage sorting" to express a concept that says the genetics aren't obeying the theory.
As noted above, adaptive radiation has been a part of evolutionary theory for a very long time. This research shows that adaptive radiation events can produce evolutionary patterns that differ from non-radiation patterns.
And as [MENTION=20697]Vulcan Logician[/MENTION] pondered, one has to wonder why creationists seem to think that modifying a model to account for new data is somehow a knock against science. The only thing I can figure is it's because in the world of creationism, things never change and deviating from scripture is viewed as heresy.
