Evolution May Make it Harder for Humans to Hold Their Liquor - Live Science


Live Science
Humans are still evolving… but before toasting to that, know this: Some of the genetic changes may make hangovers worse, a new study finds. So far, only certain populations have genetic adaptations that make it hard for them to process alcohol, but ...

Mapping the 'Conflict Zones' Between Sprawl and Biodiversity - CityLab


CityLab
By 2030, the world is expected to add another billion people or so, bringing the total population to roughly 8.5 billion. And with humans becoming increasingly urban, sprawl will only get worse, taking up precious space that wild birds, mammals, plants ...

Small Population Size Effects: Genetic Drift

San Marcos - United States
