Centralized migration accelerates adaptation and drives parallel evolution, emphasizing the key influence of spatial organization on evolutionary dynamics across systems from pathogen transmission to ...

Evolution describes changes in inherited traits of populations through successive generations. To fully understand the science of ecology, one must first be able to grasp evolutionary concepts. Aa Aa ...

Someone once asked me “Is evolution still happening?” My brief answer was “Of course, it’s always happening.” I would have gone on to explain a bit, but the questioner turned and walked away. That ...

At some point in the deep past, humans may have come frighteningly close to disappearing altogether. Here’s what we know, ...

The concept of punctuated equilibrium was, to some, a radical new idea when it was first proposed by Stephen Jay Gould and Niles Eldredge in 1972. Now it is widely recognized as a useful model for one ...

Example of a spatial configuration of a 2D expanding and evolving colony of cells, a typical simulation representing an example with 3 mutations. The individual graphs represent different snapshots in ...

Life in the wild is never constant; animals adapt quickly if they are to survive. Climate change, the reduction of habitats, ...

Researchers have shed new light on how viral evolution, population immunity, and the co-circulation of other flu viruses shape seasonal flu epidemics. Researchers have shed new light on how viral ...
