In general, evolution is a long, slow process of tiny changes passed down over generations, resulting in new adaptations and even new species over thousands or millions of years. But when living things are faced with dramatic shifts in the world around them, they sometimes rapidly adapt to survive better.



Summary

Evolution typically occurs gradually through accumulated small changes over vast timescales. This process drives adaptation and the emergence of new species. However, drastic environmental changes can trigger rapid evolutionary adaptation in organisms. Facing immediate pressures, populations may evolve at an accelerated pace to enhance their survival and reproductive success in the altered environment. This demonstrates that while slow and steady is the norm, evolution possesses the flexibility to respond quickly to urgent challenges.
