Evolution: Bioluminescent Courtship as an Engine of Diversity
نویسنده
چکیده
A new study finds that the evolution of bioluminescent sexual displays drives high species richness across animal lineages, providing a crucial link between microevolutionary and macroevolutionary explanations of biodiversity.

Male courtship attractiveness and paternity success in Photinus greeni fireflies.
Although female mate choice and male sperm competition have separately attracted much attention, few studies have addressed how precopulatory and postcopulatory episodes of sexual selection might interact to drive the evolution of male traits. In Photinus fireflies, females preferentially respond to males based on their bioluminescent courtship signals, and females gain direct benefits through ...
متن کاملHigh Rates of Species Accumulation in Animals with Bioluminescent Courtship Displays
One of the great mysteries of evolutionary biology is why closely related lineages accumulate species at different rates. Theory predicts that populations undergoing strong sexual selection will more quickly differentiate because of increased potential for genetic isolation [1-6]. Whether or not these population genetic processes translate to more species at macroevolutionary scales remains con...
متن کاملDeterminants of reproductive success across sequential episodes of sexual selection in a firefly.
Because females often mate with multiple males, it is critical to expand our view of sexual selection to encompass pre-, peri- and post-copulatory episodes to understand how selection drives trait evolution. In Photinus fireflies, females preferentially respond to males based on their bioluminescent courtship signals, but previous work has shown that male paternity success is negatively correla...
متن کاملFirefly Courtship: Behavioral and Morphological Predictors of Male Mating Success in Photinus greeni
Differences among males in their mating success constitute an important aspect of sexual selection (Darwin 1871), and many male sexual traits have been identitied that enhance male competitive ability or attractiveness to females (Andersson 1994). Male-biased breeding sex ratios are expected to intensify male–male competition and simultaneously cause females to become more selective due to redu...
متن کاملRepeated and Widespread Evolution of Bioluminescence in Marine Fishes
Bioluminescence is primarily a marine phenomenon with 80% of metazoan bioluminescent genera occurring in the world's oceans. Here we show that bioluminescence has evolved repeatedly and is phylogenetically widespread across ray-finned fishes. We recover 27 independent evolutionary events of bioluminescence, all among marine fish lineages. This finding indicates that bioluminescence has evolved ...
