Chernobyl: a DNA discovery on substitution rates
On Friday, BBC has brought us news about an interesting paper on evolution:
The answer sounds logical but it's always helpful to confirm a consistency check and to learn some additional details that don't directly follow from consistency: the answer is that the affected species are those that have accumulated high substitution rates during past environmental perturbations - as reflected by cytochrome b mitochondrial DNA base-pair substitution rates.
However, let me admit that when I look at the graph on page 7/11, I am somewhat unimpressed by the quality of the correlation coefficient between the abundance slope and the substitution rate.
