Researchers find novel courtship behavior in female Drosophila santomea, a fruit fly species native to the island of São Tomé off the coast of West Africa .
Researchers found that evolution has reused a pair of neurons that regulates a conserved female abdomen behavior to also control wing spreading.
The discovery of this newly evolved novel behavior is particularly exciting to the evolutionary neurobiology lab.
By focusing on female-initiated behaviors, the study highlights what is possible in evolution's toolkit, sparking new questions about the complex dynamics of communication in the animal kingdom.
