What is the selfish gene theory? How does it depart from traditional biologists’ views of organisms and evolution?<\/p>\n\n\n\n

The selfish gene theory, developed by evolutionary biologist and author Richard Dawkins, contradicts traditional perspectives in biology and evolution. He argues that life is best understood from the genetic perspective as opposed to the organismal perspective.<\/p>\n\n\n\n

Read on for more about the selfish gene theory.<\/p>\n\n\n\n\n\n\n\n

The Logic Behind the Selfish Gene Theory<\/strong><\/h2>\n\n\n\n

All behaviors in nature lead back to genes trying to copy themselves, which is the core of the selfish gene theory. Selfishness and altruism can both be explained by animals acting to protect either themselves or their relatives (who will, by definition, share many of their genes).  <\/p>\n\n\n\n

Note that, due to countless variables, it\u2019s impossible to say exactly what effect a behavior will have on a creature\u2019s long-term chance of survival<\/a>. Therefore, all of the examples throughout this essay are presented with what we assume <\/em>the effects of those actions will be.<\/p>\n\n\n\n

Emperor penguins demonstrate selfish behavior when they push each other into the water to check for predators before diving in themselves. Meanwhile, bees demonstrate altruistic behavior when they sting to defend their hives\u2014while they may drive off creatures that would have eaten the hive\u2019s food source, the honey, the bees themselves often die in the process. <\/p>\n\n\n\n

However, selfishness and altruism aren\u2019t always immediate life-or-death acts. For example, a bird that gives an alarm call upon seeing a predator is being altruistic, because the bird might draw that predator\u2019s attention to itself. It\u2019s a relatively small risk compared to that of a bee stinging an intruder, but it still counts as altruism.<\/p>\n\n\n\n

For all the earlier talk of creatures reproducing, it must be understood that the gene <\/em>is the unit of inheritance\u2014not the creature, species, or population. Therefore, creatures\u2019 selfishness and altruism are both rooted in gene selfishness.<\/strong> <\/p>\n\n\n\n

Animals, including humans, are essentially organic machines built by genes, and genes are designed to survive and reproduce. Genes are selfish\u2014not consciously, of course, but those that still exist have out-competed countless other genes. This is ultimately selfish behavior\u2014that is, behavior that benefits the individual at the expense of others. <\/p>\n\n\n\n

Genes also show their selfishness because of the fact that altruism toward outside groups is rare, and toward different species is almost unheard of. For example, a human killing another human is one of the worst crimes possible, but we kill animals every day for food, in self-defense, or simply for sport. This species bias supports the selfish gene theory.<\/p>\n\n\n\n

Humans are something of a special case when it comes to selfishness and altruism, as well as the selfish gene theory generally. Unlike other animals, we can be taught altruism and be convinced to go against our basic selfish nature\u2014although to exactly what extent is part of the ongoing nature vs. nurture debate.<\/p>\n\n\n\n

Nature Seeks Stability<\/strong><\/h3>\n\n\n\n

Since genes themselves aren\u2019t living organisms, it may be confusing to talk about their \u201csurvival\u201d; substituting the word \u201cstability\u201d might help to clarify the matter. By definition, something that\u2019s unstable\u2014whether it\u2019s a single molecule or a population of animals\u2014will keep changing until it finds a stable form. For primordial molecules, this happens by chance; atoms randomly bump into each other until they happen to land in a form that sticks. <\/p>\n\n\n\n

In animal populations, the selfish gene theory gets a lot more complex. As we\u2019ve discussed, a population of altruistic animals could be easily overtaken by selfish individuals, and therefore can\u2019t be considered stable. Similarly, a population of all selfish animals will be unstable because it\u2019ll fight against itself, inevitably growing weaker until it\u2019s overwhelmed by other types of individuals. <\/p>\n","protected":false},"excerpt":{"rendered":"
