The world of viruses and their critical roles in shaping ecosystems, driving evolution, and impacting human health

Abstract

The world of viruses is vast and diverse, influencing nearly every aspect of life on Earth. Although invisible to the naked eye, viruses are among the most abundant entities on the planet, outnumbering all other life forms combined. Found in every environment—from the depths of the oceans to the human body—viruses play critical roles in shaping ecosystems, driving evolution, and impacting human health.
