A few words about horns

A few words about horns in beetles... very diverse small to huge for >150 years people were curious about what purpose(s), if any, they serve

Your task! Before you are containers with ~20 individual Onthophagus nigriventris Note the very conspicuous horns in at least some of the animals. Your task is to find out what purpose those horns might serve? Using these beetles and your observations, please develop a number of hypotheses about the potential uses of these horns. Then brainstorm about experiments that might be used to test these hypotheses. Can you design and execute some version of these experiments with the materials here at hand? If so, please share your experiment-idea with us and we will execute it together. If not, still share the idea with us, and I will see if I might have data that match your experiment
