Can bees be intelligent and do they have hearts

Are bees intelligent?

A honey bee brain has fewer than one million neurons, while a human brain has around one hundred billion neurons. Bees are capable of a wide range of behaviors, although they have a brain the size of a peppercorn and a nervous system that is simpler than many other animals. At one time, scientists believed that insects were not very interesting to study with regard to their intelligence, assuming that their behaviors were stereotypical and fixed - more like robots than living things. We now know that many insect behaviors are dependent on their capacity to assess local conditions and that they can adjust their behavior depending on their perceptions, much like vertebrates. This flexibility is especially true for bees and indicates a higher level of intelligence than other insects.

Bees see color and have well-developed olfactory (smell) and gustatory systems with a fondness for sweets. Included in their behavioral repertoire is an ability to learn the location and identity of their home as well as the spatial features of the local neighborhood, to identify nest mates with an awareness of social roles, and to learn about resource availability. Honey bees use a symbolic language and employ such basic concepts as sameness and difference. One indicator of intelligence is the ability to profit from learning experience, and bees' capacity to learn complex behaviors has been amply demonstrated. Because of their highly social lives and sophisticated behaviors, bees are thought to be among the most intelligent insects.

The neural architecture of the honey bee brain is particularly intriguing. The small brain has many highly organized and sculpted regions that are easily distinguishable under a microscope. One of these brain regions, called the mushroom bodies, has attracted the attention of behavioral biologists and neurobiologists alike because of its unique size, shape, and connectivity. Mushroom bodies appear larger in animals that are highly social, and smaller in insects that live a solitary lifestyle. Neuroscientist Susan Fahrbach at Wake Forest University described the explosion of research interest in this part of the bee brain over the last decade.

The discovery by biologist Ginger Withers and others, working at the University of Illinois in Urbana- Champaign, that honey bee brains exhibit neural plasticity during the life of an adult bee has initiated both behavioral and neurobiological studies with bees. Complex forms of learning and other cognitive processes, as well as brain structures, chemistry, and neurophysiology, have been explored in great detail by Randolf Menzel and his colleagues at the Free University of Berlin. These studies aim to connect the bee brain structures to their possible functions. The mushroom bodies appear to be involved with processing information acquired through both odor and vision, essential to the life of the bee.

Does a bee have a heart?

Yes, bees have hearts, but they are quite different than the four-chambered hearts of mammals like humans. Bees, like all insects, have an open circulatory system without veins or arteries, so there are places in its body where the body fluid washes directly around the tissues and organs. A pulsating, muscular tube along its back, called the dorsal vessel, pumps the hemolymph from the abdomen to the thorax and then to the head, squeezing the hemolymph into each section of the body.

Additional pulsating organs, called simple hearts, or ostia, are located at other points in the body and boost the fluid's circulation. As the muscles relax, the fluid circulates back into the dorsal vessel, moving more or less quickly depending on the insect's activity level. Unlike blood, hemolymph does not carry oxygen, so this relatively inefficient system is adequate to distribute nutrients to the cells.
