He believed that, on the contrary, sex and the associated diversity allows the brothers to avoid competition with each other, as they are taking a slightly different ecological niches. For an analogy, suppose that in a small village blacksmith's family lives. If all five c***dren of a blacksmith inherited his craft, the four of them will die of starvation, since only one village blacksmith. But if they have different professions (weavers, roofers), their total income would be more, as they will not be competing for a place under the sun.The third hypothesis suggested American biologist Leigh Van Valen. It was called "Red Queen Hypothesis" by the name of a character from the works of Lewis Carroll. For the Red Queen from Carroll fastest run was the only way to stay in place. According to Van Valen, sex emerged as a way of individual pest. In the course of this struggle does not take place no victory - and the individual parasites are evolving at the same time, remaining in the same. I am awash with this heat, this quaking sensation all over my body and the soft flesh between my legs is already pounding with need. As a dog walker passes close by we pause, breathing hard as we lean forehead to forehead. It’s decision time and it has come up on us so suddenly, surprising us with this intensity. I know he is fighting with himself, trying to hold back so I take control. What is this life for if you turn your back on fantasy nights like this? I simply cannot let this chance to go by unheeded so I put my hands at his hips and gently push, flicking my eyes to the sand dunes rearing up behind the beach. They are glowing gold in the early evening sun and the breakers are crashing in. Sea gulls whirl above us in the bright blue sky. Decision made, we find the perfect spot. The walker has long since moved away and there isn’t a soul to be seen. We spread out our shirts and lie down together. Our mouths join again and I cannot hold back the needy groan. The kiss deepens.
