Me(me), Not You

Sex is probably the biggest part of life. There are other important things, like surviving, but even survival needs sex. For our genes to survive more than one life time or generation, we need to pass them on, and the only way to do that is through reproduction - which means sex. This works fine for genes, but for meme endurance, it undergoes a slight twist. Memes cannot be passed on from an organism to another through sexual or asexual reproduction, their travel plans are a little bit more complex. Memes are cultural ideas that travel through brains. They have to compete against each other and make themselves as conspicuous and flamboyant as possible because their existence depends on how many organisms "like" them. The imitation of one meme creates a new meme that can be from extremely similar to the original one, to having only a small resemblance. Ideas change with everyone that thinks about them, this is why memes aim to be ideas that are attractive in its original way. The less change they undergo in brains, the clearer the imitation of the original, which means the original will last longer. The change and development in the world affects the memes plans, so it is indeed very hard for them to pass on from one person to another with minimum change made to them.
