According to the Modern Synthetic Theory of Evolution, evolution is most accurately defined as a change occurring at the level of a population, specifically a change in its:
A.
Gene (allele) frequency across successive generations
A. Gene (allele) frequency across successive generations

The human vermiform appendix, which was functional and larger in herbivorous ancestors but is reduced and largely non-functional in modern humans, is an example of a/an:
The hypothesis proposing that life originated from non-living organic and inorganic molecules through a gradual process of chemical evolution on early Earth was independently put forward by:
The increase in frequency of dark-coloured (melanic) peppered moths (Biston betularia) in soot-darkened, polluted industrial regions of England, compared to light-coloured moths, is a classic example of:
A. Industrial melanism (natural selection in action)

When two populations of a species become physically separated by a barrier such as a mountain range, river or ocean, preventing gene flow between them and eventually leading to the formation of new species, the process is called:
The diversification of Darwin's finches on the Galapagos Islands into species with different beak shapes and sizes suited to different food sources, all from a single common ancestor, is the best example of:
