Bees actively adjust flower choice based on color and distance: Updating 'flower constancy' beyond Darwin's theory | ScienceDaily
Since Darwin's time, the phenomenon known as flower constancy -- i.e., where insects consistently visit the same flower type even when many others are also present -- has been understood as a passive behavior to reduce the effort of remembering different flower types. However, researchers have now shown via experimentation with bees that this behavior is an active strategy in which bees balance the time required for memory retrieval and moving between flowers, thereby realizing efficient foraging.
Earthworms reveal an evolutionary mechanism that could defy Darwin
In 1859, Darwin imagined evolution as a slow, gradual progress, with species accumulating small changes over time. But even he was surprised to find the fossil record offered no missing links: the intermediate forms which should have told this story step by step were simply not there. His explanation was as uncomfortable as it was unavoidable: basically, the fossil record is an archive where most of the pages have been torn out.
International research team analyzes the genetic basis of ant evolution
The existence of ant colonies was a mystery even to the famous naturalist Charles Darwin. How could evolution produce workers that cannot reproduce? Darwin assumed that workers increase the reproductive success of their queen, thereby explaining the so-called reproductive division of labor: males provide sperm, which the queens store and use to fertilize eggs throughout their lives. Workers search for food, care for the brood and defend the nest, but do not reproduce.
