Competitive exclusion among self-replicating molecules curtails the tendency of chemistry to diversify.
Nat Chem

The transition of chemistry into biology is poorly understood. Key questions include how the inherently divergent nature of chemical reactions can be curtailed, and whether Darwinian principles from biology extend to chemistry. Addressing both questions simultaneously, we now show that the evolutionary principle of competitive exclusion, which states that a single niche can be stably occupied by only one species, also applies to self-replicating chemical systems, and that this principle diminishes the tendency of chemistry to diversify.

The evolution of cancer cells parallels species evolution in numerous ways. Variations arise and spread under the pressure of competition between cancer cells. Current investigations of tumor evolution echo earlier debates between biologists.

Interest in the study of domesticated plants increased near the end of the 18th century, mainly because of their economic potential. In the 19th century, there was a new focus on the historical understanding of species, their origin, changes in their distribution, and their evolutionary history. Charles Darwin developed an extended interpretation of species domestication, considering variations, reproduction, inheritance, and modification as standard processes between wild and domesticated organisms.

Mutualism is considered a major driver of biodiversity, as it enables extensive codiversification in terrestrial communities. An important case is flowering plants and their pollinators, where convergent selection on plant and pollinator traits is combined with divergent selection to minimize niche overlap within each group. In this article, we study the emergence of polymorphisms in communities structured trophically: plants are the primary producers of resources required by the primary consumers, the servicing pollinators.
