Evolution Genetics Genomics Intelligent Design stasis

Ghost worms unchanged in form for 275 million years but show “highly distinct” genetics?

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.

Big Data study of termites forces rethink of their evolution

“Often, researchers construct a phylogeny using a single gene. This can, however, give an inaccurate picture of the relationship between species — and can incorrectly place them.” So the industrious team studied “used up to 4065 genes from each termite species to construct the phylogeny.” Good for them. But it raises the question, why—in the age of Big Gene—doesn’t everyone do that, instead of loudly proclaiming an evolutionary history based on a handful of genes? One is much less inclined to dismiss the evidence of thousands than a handful.

More Salt in the Peppered Moth’s Wounds

The entire history of Kettlewell’s Peppered Moth experiment is littered with problems: doctored photographs, wrong assumptions and slim evidence, followed by genetic analysis revealing that the protein exons coding for color were not changed, but, rather, a transposon (non-random) was inserted in an intron (“junk DNA”). And now there’s this paper. It seems that the Read More…
