Genes can influence behavior for their benefit 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
In the endless struggle for survival and reproduction, genes will go to great lengths to ensure their own perpetuation. One way they accomplish this is by influencing behavior in their host organisms. By shaping behavior in ways that increase the chances of their own replication, genes can effectively promote their own survival. Take, for example, the behavior of a mother bird diligently caring for her chicks. This seemingly selfless act can be attributed to the genes that code for such behaviors. These genes have been selected for over generations because they increase the likelihood of the mother bird's offspring surviving and passing on those same genes. In a similar vein, genes can also influence behaviors that benefit the larger group or species to which the organism belongs. This seemingly altruistic behavior can be explained by the fact that genes are not solely concerned with the survival of individual organisms, but rather with the continuation of their own genetic material. If promoting the survival of the group enhances the chances of their own replication, then genes will favor such behaviors. It is important to remember that genes are not sentient beings with a conscious agenda. Instead, they are biochemical entities that have been shaped by the forces of natural selection. The behaviors they influence are not the result of a grand plan, but rather the cumulative effect of millions of years of trial and error.- The concept that genes can influence behavior for their benefit is a fundamental aspect of evolutionary biology. By understanding how genes shape behavior, we can gain insights into the complex and often seemingly irrational actions of living organisms. This perspective sheds light on the underlying mechanisms driving the diversity and adaptability of life on Earth.
