Scientists discovered fossilized dinosaur footprints at Colorado's Dinosaur Ridge indicating that male dinosaurs, possibly similar to T. rex, performed courtship dances resembling a moonwalk to attract females, suggesting the site was a major lek for mating displays, and providing new insights into dinosaur behavior.
Scientists discovered evidence of a unique dinosaur courtship ritual involving 'moonwalk'-like movements at Dinosaur Ridge, Colorado, revealing complex social behaviors and lekking displays similar to modern birds, dating back around 100 million years.
A study by the University of California, Santa Barbara, suggests that testosterone in men is more closely linked to romantic behavior and courtship efforts rather than sexual desire. The research, involving 41 men over 31 days, found no correlation between elevated testosterone levels and increased sexual desire. Instead, higher testosterone was associated with increased courtship efforts during social interactions with potential romantic partners. These findings challenge the common practice of prescribing testosterone for low sexual desire in men with normal hormone levels.
A study on three-spined stickleback fish sheds light on animal decision-making processes and the trade-offs they face. Male sticklebacks must balance territorial defense, courtship, and caring for offspring during the breeding season. The study found that males generally prioritize territorial defense over courtship, with some variation in individual strategies. Gene expression analysis revealed unique molecular responses when faced with conflicting demands, potentially related to reward and motivation pathways in the brain. These findings suggest ancient mechanisms driving complex decision-making across various animal taxa.
A new study published in Nature Neuroscience reveals that dopaminergic error signals play a crucial role in retuning social feedback during courtship. The researchers found that dopamine neurons in the ventral tegmental area (VTA) encode social interaction and promote reinforcement learning through social prediction error. This study adds to the growing body of evidence highlighting the importance of dopaminergic signaling in social behaviors and provides insights into the neural circuits underlying courtship and mate selection in animals.
