Rapid (contemporary) evolution
The interface between ecology and evolution
When the short time-scale evolution synchronizes with the time-scale of population & community dynamics dynamics, evolution alter ecological outcomes that previous theories expected.
What is a fuel of rapid evolution?
Rapid evolution can be promoted by four factors (relatively important from first one):
- Standing genetic variation
- Selection
- Mutation
- Gene flow
Adaptive introgession
Migration load

Strong vs weak selection
Rapid evolution are usually expressed by the quantitative genetic model under an assumption of weak selection. However, in nature, it is suggested that strong selection drive rapid evolution. May we use conventional evolutionary model to derive rapid evolution?
