Apparently, the ancestor of HIV has been present since at least 32 thousand years ago. Even more.
Human Immunodeficiency Virus (HIV) is still considered a newcomer among other human pathogens. As is known, is a new unknown pathogens emerge and spread in the last few decades alone.
For that reason, some researchers find the origin of the virus. At first they suspected that the Simian Immunodeficiency Virus (SIV), virus in primates was the one who gave birth to HIV. SIV virus itself allegedly was several hundred years older than HIV.
After doing some research, Preston Marx, virologist from Tulane University found otherwise. SIV virus seems to have aged at least 32 thousand years. That is, the virus was already present, you could say almost simultaneously with the appearance of humans, long before the presence of HIV.
