A cosa servono i virus?

Ciò che sta costringendo mezza umanità ai domiciliari nel 2020 è, in realtà, uno dei principali motori dell’evoluzione biologica e dell’intera storia naturale del nostro pianeta Quando, cinque anni fa, lavoravo alla teoria dell’endogenosimbiosi mai avrei potuto immaginare che buona parte dell’umanità sarebbe stata coinvolta da una pandemia virale che avrebbe costretto la quasi totalità…

Evolutionary biology: two new studies confirmed the “endogenosymbiosis” hypothesis

Endogenosymbiosis (from the combination of the words: endo-geno-symbiosis), such as the capacity of “gene carriers” (viruses, retrovirus and bacteriophages) to share parts of their genome in an endogenous symbiotic relationship with their hosts, was proposed in 2015 by Roberto Cazzolla Gatti, Ph.D., associate professor in ecology and biodiversity at the Tomsk State University (Russia), in…

Cooperation, not struggle for survival, drives evolution

An empirical experiment confirms a new hypothesis on the evolution of life Many theories and hypotheses suggest that competition tends to differentiate ecological requirements after repeated interactions and allows biodiversity. Even if the mechanisms that allow species to evolve, coexist, compete, cooperate, or become extinct are becoming more and more understood, the factors that allow…
