Summary:
- Water fleas, also known as Daphnia, are tiny crustaceans that live in freshwater environments. They are an important part of the aquatic food chain, serving as food for larger animals.
- Researchers have discovered that water fleas can rapidly evolve to swim faster in response to the presence of predators. This ability to adapt and evolve quickly helps the water fleas survive and avoid being eaten.
- The study found that water fleas can increase their swimming speed by up to 30% within just a few generations, demonstrating the remarkable adaptability of these small creatures to changing environmental conditions.
