Evolution favors adaptations that increase gene survival from "summary" of The Selfish Gene by Richard Dawkins,Charles Simonyi Professor of the Public Understanding of Science Richard Dawkins,David Dawkins,RICHARD AUTOR DAWKINS
The process of evolution can be summed up in one simple phrase: survival of the fittest. But what does it truly mean to be the fittest? In the intricate dance of natural selection, it is the adaptations that increase gene survival that are favored above all others. These adaptations are not chosen consciously, of course. They are simply the result of random mutations that happen to confer some advantage to the organism in its environment. Over time, these advantageous traits become more common in the population as those individuals carrying them outcompete their counterparts. This idea of adaptations increasing gene survival is at the heart of the concept of the selfish gene. Genes are the fundamental units of heredity, the building blocks of life. And they are selfish in the sense that their primary goal is to survive and replicate. Every adaptation that increases the likelihood of a gene being passed on to future generations is favored by evolution. This can manifest in many different ways, from physical traits that aid in survival and reproduction to behaviors that increase the chances of mating or cooperation with kin. In the grand scheme of things, it is all about ensuring the survival of the genes themselves. Organisms come and go, but genes persist through generations, carrying the information that shapes life as we know it. So, the next time you marvel at the diversity and complexity of the natural world, remember that it is all driven by the simple principle that evolution favors adaptations that increase gene survival.
