ENV has a new post up regarding the evolution of the mammalian ear.
| Quote | Secondly, if one reads the paper carefully, it is curious that (as noted by the authors), "Given the phylogeny, the [definitive mammalian middle ear] evolved several times independently." An earlier paper in Nature, published in 2007, reported on the discovery of a fossil of a eutriconodont mammal species called Yanoconodon (Luo et al., 2007). Curiously, as explained by this editor's summary of the paper,
| Quote | | The situation is not as clear-cut as it seems. The evolutionary relationships of the fossil suggest that either the "modern" middle ear evolved twice, independently or that it evolved and was then lost in at least one ancient lineage. |
It thus appears to be the case that the middle ear evolved independently at least twice: in monotremes and in placentals and marsupials. Multiple occurrences of difficult evolutionary trajectories is something that is not easy to square with the standard neo-Darwinian narrative. |
Whenever I see a quote like that from a 'summary' of the paper the alarm bells start ringing. The paper is behind a paywall but perhaps someone can check to see what was said in the body rather than in the 'teaser' summary text.
Oh, and heads we win tails you lose:
| Quote | | There are a few points that are worth raising here. Firstly, even supposing that the hypothesis of common ancestry is valid, this lends little traction to neo-Darwinism (one has to distinguish between pattern and process) and it does nothing to undermine the hypothesis of design. ID, in its purest sense, has nothing to say about common ancestry. ID does, however, open up the possibility that universal hereditary continuity may be false, perhaps radically so. Many of us Darwin critics, therefore, also happen to be skeptical of common ancestry. But it would not invalidate our position on ID if common ancestry turned out to be true. |
