Commonly, sexual selection changes with the seasons and level of development of an organism. “Seasonal changes in pheromone-detection ability and olfaction sensitivity over the reproductive cycle have been observed in mammals, birds, and teleost, but such seasonal shifts in the visual system are less well-developed” It has been hypothesized that three-spine sticklebacks, Gasterosteus aculeatus, are more sensitive to red during the summer than the winter, which could be linked to the desire to…

Heavier Procambarus clarkii have higher success rates in agonistic interactions Animals in a community are always competing with one another for the resources that the area has to offer such as food, space, and water.

To avoid this, clarkii size each other up before engaging in combat to determine if dominance is worth the risk,…

The Evolution of Animal Genitalia; Sex Style Genitals are the fastest evolving organs in the animal kingdom. Rapid and divergent evolution of male genitalia represents one of the most general evolutionary patterns in animals with internal fertilization. In fact, in recent studies, it has been revealed that male genitalia evolve six times faster than limbs or dewlaps, (a fold of loose skin hanging from the neck or throat of an animal, especially that present in many cattle) explaining the large…

differences between the social expression of gender as well the physical underpinnings of gender have been intensely debated over the last few decades.
