Can melting glaciers influence the acceleration of continental drift and volcanic activity? New research suggests that this ...

Aa Aa Aa Natural selection, genetic drift, and gene flow are the mechanisms that cause changes in allele frequencies over time. When one or more of these forces are acting in a population ...

As Gautschi et al. explain, genetic drift, arguably the most powerful evolutionary force at work in small populations, results from the random sampling of alleles from one generation to the next ...

Around 10,000 years ago, as the last Ice Age drew to a close, the drifting of the continent of North America, and spreading ...

Melting glaciers 10,000 years ago sped up continental drift and volcanic activity, a process that could repeat as modern ice ...
