The evolution of honey bee brains: Specialized neurons in some insect brains, related to highly evolved behaviors, may have developed from a multifunctional ancestor

Researchers have proposed a new model for the evolution of higher brain functions and behaviors in the Hymenoptera order of insects. The team compared the Kenyon cells, a type of neuronal cell, in the mushroom bodies (a part of the insect brain involved in learning, memory and sensory integration) of 'primitive' sawflies and sophisticated honey bees. They found that three diverse, specialized Kenyon cell subtypes in honey bee brains appear to have evolved from a single, multifunctional Kenyon cell-subtype ancestor. In the future, this research could help us better understand the evolution of some of our own higher brain functions and behaviors.

Yes, glyphosate is harmful to bees

Many people assume that herbicides, since they are designed to kill plants, are not toxic for bees. This, however, is far from the truth. In our latest briefing, we list scientific findings that reveal that glyphosate-based herbicides are toxic to bees in many ways. Bees are exposed to these chemicals either by direct contact or by ingestion via food and contaminated water. Glyphosate-based herbicides are widely used to combat weeds in agriculture, towns and cities, peoples’ homes and gardens and even in nature-protected areas.
