Evolution is often perceived as being a “directional” or “adaptive” process. We often think of species evolving to become stronger or faster, or to have sharper teeth, for example.

The case appears to be one of the clearest examples researchers have found yet of non-adaptive evolution, although selection still plays a role in maintaining the original gene set. The research ...

This view is in sharp contrast to adaptationist explanations of change in stelar morphology expressed by other authors and provides an example of non-adaptive change in evolution. Paleobiology, ...

The introduction of noise into an evolutionary iterated prisoner's dilemma model can promote the evolution of strategy memory. In this paper, an analysis in terms of Ashby's (1956) law of requisite ...

"Non-adaptive evolution or Neutral Theory is when there is no selective pressure on a gene, resulting in an accumulation of random mutations in the gene sequence over time," he says.

The swarm of 237 weevils in a single genus inhabiting Macaronesia is the result of a blend of adaptive and non-adaptive evolution in old volcanic archipelagos. It is the specificity of their ...

Department of Physics, Bose Institute, Kolkata, India Strictly adaptive walks on uncorrelated and correlated fitness landscapes have been a subject of intense research. However, some experimental ...

This suggests that neutral (non-adaptive) evolution may be more important in shaping inner ear morphology than previously thought. A new study of the inner ears of a diverse group of mammals sheds ...

Strictly adaptive walks on uncorrelated and correlated fitness landscapes have been a subject of intense research. However, some experimental findings tend to advance the notion of non-adaptive ...
