Lightly seared on the reality grill.
On the subject of evolution and genetics, fairly recently, the genetic mutation responsible for the classic peppered moth example of evolution has been identified.
The industrial melanism mutation in British peppered moths is a transposable element

The industrial melanism mutation in British peppered moths is a transposable element
Here we show that the mutation event giving rise to industrial melanism in Britain was the insertion of a large, tandemly repeated, transposable element into the first intron of the gene cortex. Statistical inference based on the distribution of recombined carbonaria haplotypes indicates that this transposition event occurred around 1819, consistent with the historical record.
