Pandoravirus is a type of giant virus discovered in 2013. It is notable for its large size and complex genetic structure, containing more than 2,500 genes, which is significantly more than most known viruses. This virus primarily infects amoebas and is found in various environments, including freshwater and soil. The discovery of Pandoravirus has challenged traditional views of viruses, as it blurs the line between living and non-living entities. Its unique characteristics have led scientists to explore the evolutionary history of viruses and their role in ecosystems, raising questions about the origins of life on Earth.
