Vegetation, soil, DNA and natural evolution

Dialogue with Sandro Pignatti on natural evolution, considering the soil as a living matrix in which the recycling of organic matter and DNA takes place. How vegetation interacts with the soil and how it is not the species that evolve but the ecosystem that contains them. The hypothesis of a still poorly understood genetic exchange in relation to the biodegradation process is raised. Recent research in soil microbiology and biodiversity highlights a functional and primordial collaboration between living beings in the exploitation of natural resources.
