Survival of the Flattest: Digital Organisms Replicate and Mutate

In this article, the author overviews on the basics of natural selection. More specifically "r selection," which is the theory that the organisms that replicate the fastest within an environment are considered to be most successful. However, in this article, they state that being the fastest at self replicating may not be the most successful method for succeeding future generations. In a digital simulation, researchers have observed that organisms were more focused towards having more control over their resources. And in another simulation where the environment induces mutations, the organism that is most resistant to mutations would likely be the most fit organism, rather than the organism that is overall more fit. This article seemed to be focusing on looking into the different types of strategies organisms may use to thrive in harsh environments.
