摘要：Although some lineages of animals and plants have made impressive adaptive radiations when provided with ecological opportunity, the propensities to radiate vary profoundly among lineages for unknown reasons. In Africa's Lake Victoria region, one cichlid lineage radiated in every lake, with the largest radiation taking place in a lake less than 16,000 years old. We show that all of its ecological guilds evolved in situ. Cycles of lineage fusion through admixture and lineage fission through spe...

摘要：Molecular clocks are the basis for dating the divergence between lineages over macroevolutionary timescales (similar to 10(5) to 10(8) years). However, classical DNA-based clocks tick too slowly to inform us about the recent past. Here, we demonstrate that stochastic DNA methylation changes at a subset of cytosines in plant genomes display a clocklike behavior. This epimutation clock is orders of magnitude faster than DNA-based clocks and enables phylogenetic explorations on a scale of years t...
