If a species looks superficially the same after thousands of years, the most likely explanation is: there is no evolution happening to that population they have evolved a level of perfection so no changes are necessary the changes are not easily observed, such as changes in immunity or metabolism they have not experienced any Gene Flow 13

What is adaptive radiation? Large-scale evolutionary patterns and trends in speciation The event when a species no longer has living members A lineage undergoes a burst of genetic divergences that gives rise to many species Changes in allele frequency that are always occurring in natural populations
