Explanation:

In a lake in Brazil, researchers have discovered a virus called Yaravirus that has a “puzzling origin and phylogeny”. The Yaravirus infects amoeba and has genes that have not been described before, something that could challenge how DNA viruses are classified. Over 90% of the Yaravirus’s genome has not been observed before. Because of the Yaravirus’s small size, it was unlike other viruses that infect amoeba and they named it as a tribute to Yara, the “mother of waters” in the mythological stories of the Tupi-Guarani indigenous tribes. The virus does not infect human cells. Although it is only now that the virus has been identified, the researchers believe that it has been present on Earth for ages. Hence only statement 2 is correct.
