Evolutionary Trajectory
An evolutionary trajectory describes the long‑term path a population follows as its genetic composition changes over generations. This article explains how selection, drift, mutation, and environmental pressures shape these trajectories.
Population Bottleneck
A population bottleneck is a sharp reduction in population size that drastically reduces genetic diversity. This article explains how bottlenecks occur, how they drive genetic drift, and why their effects persist for generations.
