Choosing you to mate: honesty brings better results

In the animal world, sparkling colors or gimmicky action are like ads to attract you to mate. But what do those ads really promise, and what percentage can be trusted? Researchers at Yale University (USA) argue that when males are forced to pay attention to the survival of their offspring, the signal it emits is completely honest and reliable. Males spend more of their energy to care for their children than to care for attractive looks.

It is not new for males to exhibit their best characteristics to attract females. And it is well known that males can 'cheat' themselves in marketing advertisements. Here, the remarkable thing that Natasha Kelly, bachelor of ecology and evolutionary biology at Yale University, the author of this study came up with is a plausible argument about honesty in ostentatious claims to ensure protect the function of male father.

Representing to seduce your partner consumes a lot of energy. When you use too much energy to maintain an attractive appearance, the energy for caring for your children will be less. Only the species that the male does not need to bother about taking care of the children, the fact that the male has a lot of publicity does not affect the maintenance of the race.

Previous research suggests that, under certain circumstances, males can 'market marketing' about parenting skills but they still succeed in breeding. On the online site Proceedings of the Royal Society B, the new model in this study examines the reliability of male mating signals when they have to take care of their offspring - an aspect overlooked in previous research.

In many species, females are responsible for raising children; therefore, although males can but they do not have to do it. Researchers at Yale University focus on studying the species that females cannot raise and males are forced to do so to maintain the race. The typical example of this is the stickleback fish.

Suzanne Alonzo, senior research author, assistant professor of ecology and evolutionary biology at Yale University, said: 'This new work shows that when males are forced to take care of their children, the show their will reliably show whether they can take care of their children well. '

'In this case, the male standing quietly in one corner may promise better fatherhood.' Kelly said.

This research was funded by the US National Science Foundation and Yale University.
