At Phys.org: Chinese fossils show human middle ear evolved from fish gills

Researchers: Embryonic and fossil evidence proves that the human middle ear evolved from the spiracle of fishes. However, the origin of the vertebrate spiracle has long been an unsolved mystery in vertebrate evolution.
EH: It seems that evolutionists have a much softer definition of what amounts to proof than in other fields of science.

At Skeptic: Why Christians Should Accept the Theory of Evolution

Larry Arnhart writes: American Christian fundamentalists reject Darwinian evolution for at least two reasons. The first is their belief that the Bible has revealed a clear teaching about the divine creation of the world that denies Darwinian evolution. The second reason is their belief that Darwinian evolution contradicts the foundational principle of the American creed Read More…

The Death of Neutral Theory

In today’s Nature, we find this article: “Synonymous mutations in representative yeast genes are mostly strongly non-neutral.” They investigated what effect “synonymous, nonsynonymous and nonsense” mutations involving “21 endogenous genes” would have on yeast. The fitness levels of synonymous and nonsynonymous fell in equal (though not ‘identical’) measure–around 75%. I don’t have access to the Read More…

Studies of co-evolution biased toward “striking and exaggerated phenotypes”, researchers say

The authors seem to suspect that “the widespread impression that coevolution is a rare and quirky sideshow to the day-to-day grind of ecology and evolution” is wrong and that new tools for uncovering it will show it to be more common. Co-evolution must require a fair amount of cooperation between utterly different life forms. If natural selection is the model, one failure would end a multi-stage process.
