Questions evolution can't answer

Evolution is explained as the best theory to fit the data. However, there are a great many key questions that the theory of evolution (and its advocates) cannot answer.


 * Why are human beings altruistic?


 * Why did sexual reproduction evolve when asexual reproduction is far more efficient?


 * Why do humans cry when sad?


 * Why do human beings have moral objections to sexual promiscuity when it is favorable to a species to have many offspring?


 * Why aren't more people sexually promiscuous, given the evolutionary advantages of increasing one's offspring?


 * Where and why did music evolve?
