Sexual Selection in Giraffes

Evolution plays a crucial role in understanding the development of complex characteristics in various organisms. One of the fascinating examples of evolution can be seen in the development of the giraffe's long neck. While initially believed to be primarily an adaptation for reaching high foliage, further research has revealed that sexual selection may also play a significant role in this trait. This raises the question: What is the primary reason that longer necks in male giraffes are favored in the context of sexual selection?
