Paper Suggests Catch 22: Neo-Darwinism Faces Either a Massive Molecular Clock Misfire, or a Major Biogeographical Conundrum

As we've discussed here in the past, molecular clocks are notoriously unreliable indicators of a lineage's evolutionary age. Typically the problem is that the molecular clock is ticking "too fast" and suggests a lineage is older than the fossil record shows. Viewed through a non-Darwinian lens, genes in different organisms seem to be more dissimilar than one would expect under an evolutionary perspective. In other words, there are more informational differences between the organisms than, ac...
