The fruit fly (Drosophila melanogaster) has long been a popular model organism for scientific research because it has a much simpler system, making it easier to study and manipulate. Even with such a simple system, fruit flies still replicate aspects of biology in more complex systems, even those of humans. Additionally, flies are fairly inexpensive to study and they have short generation times, meaning you can observe a fly’s entire lifespan in just a few weeks and several generations in mere months.

In my latest report for STEAM Register.com, I cover new research in which scientists used fruit flies to study emotions in humans. They found that, by breaking emotion down into five “primitives,” flies experience something analogous to a negative emotional state such as fear.
