Evolutionary processes work at multiple levels

Evolutionary processes work at multiple levels

To shape whole communities. Article at Phys.org. The introduction:

“Evolutionary theory has long held that natural selection largely operates at the level of individuals. Findings from Northern Arizona University researchers, recently published in the Annual Review of Ecology, Evolution, and Systematics, suggest that selection can also occur at multiple levels to shape whole communities. This multi-level selection arises from the interactions of key species that cascade to alter communities and ecosystems.”
