Not as long as Darwin reigns. Darwin’s trolls can work big magic.
From “Mixed Bacterial Communities Evolve to Share Resources, Not Compete” (ScienceDaily, May 15, 2012), we learn
Predicting how species and ecosystems will respond to new environments is an important task for biology. However, most studies of evolutionary adaptation have considered single species in isolation, despite the fact that all species live in diverse communities alongside many other species. Recent theories have suggested that interactions between species might have a profound effect on how each species evolves, but there has been little experimental support for these ideas.
There would be way more if Darwinism wasn’t the local profbot’s iron rice bowl. Anyway this:
The research team, from Imperial College London, found that bacteria that evolved in a mixed community with other species altered their feeding habits to share resources more effectively amongst themselves and to make use of each other’s waste products in a cooperative manner. In contrast, when grown alone, the same species evolved to use the same resources as each other, thereby competing and impairing each other’s growth.
