This not only explodes the idea that the white working class somehow voted as a monolithic bloc in favor of leaving the EU, but also hints at why times of economic and social upheaval push populations toward the right.

Unfortunately, recent evidence has shown that such an influx could not overcome the permanent forces that continue to push populations into poverty traps [ 27].
Complex traits targeted by means of correlative approaches, and especially those regarding climatic adaptation, are expected to reveal small changes in allele frequencies that push populations to a new optimum [ 35].
There are a number of other studies that have reported similar findings in a range of taxa [ 56- 61], suggesting that selection (or plasticity; this study) can frequently be strong enough to push populations to diverge in reproductively important features despite gene flow.
Generous immigration quotas and tax incentives designed to boost the birth rate have pushed population growth to its fastest pace since the years just after World War II.
The current finding that the risk of extinction is not magnified in populations with small initial genetic effective population size intriguingly suggests that the reproductive fate of diploid males crucially affects the speed with which the postulated vortex [ 36] pushes population of species with sl-CSD towards extinction.
Such seals are natives of the North Atlantic and Arctic, but scientists believe a growing population -- and shifts in climate and food sources -- have pushed populations farther south.
Meanwhile, trawlers are netting bycatch that include marine mammals and even seabirds – as many as 320,000 seabirds are being killed annually when they get caught in fishing lines, pushing populations of albatrosses, petrels and shearwaters to the edge of extinction.
The disappearance of most aquatic habitats and productive savannas induced local extinction of almost all humidity-dependent species in the lower altitude areas and pushed populations to peripheral wetter regions [9], [10].
