A new study has shed light on homosexuality, and why it might have evolved. 'It highlights several promising directions for future research by anthropologists and psychologists interested in the evolutionary and social contexts of same-sex behaviour,' he added. Based on these insights, Professor Savolainen suggests SSB 'probably' evolved as a survival strategy to help highly social species survive environmental challenges. Same-sex behaviour (SSB) was more common in species facing harsh ecological conditions. Meanwhile, even male burying beetles will engage in same-sex behaviour when females are scarce, because same-sex mating alone reduces chances to display mating potential.
