Sentence examples for much evolutionary change from inspiring English sources

It is not at all clear how much this would revolutionise biology, nor how Gould might reconcile this kind of multi-level selectionism with his other belief that much evolutionary change is essentially random.

The other, by Robert Moyzis of the University of California, Irvine, and his colleagues, asks a broader question: how much evolutionary change has happened since Homo sapiens climbed out of his African cradle and began to colonise the world?

Biologists have long had difficulty determining how much evolutionary change comes from new species being formed and how much from gradual changes that accumulate within species over time.

To quantify how much evolutionary change we expect in the absence of harvesting, we ran 2500 replicates of our model for the full 150 years without harvesting.

The view that much, if not most, of evolutionary change at the molecular level was determined by random genetic drift and not natural selection was highly controversial.

Overall, quantitative analyses corroborated our qualitative analyses and revealed that pressure-related ideas were relatively common in student explanations of evolutionary change, although much less so in trait loss scenarios than in trait gain scenarios (Fig. 2).
