The oldest known virus is the Gokushovirus, which was first discovered in a 30,000-year-old caribou fossil in Yukon, Canada. This giant virus is named after the town in which it was located – Gokushovirus – and is thought to have existed since the Pleistocene Epoch.
The Gokushovirus is an icosahedral virus which is made up of 210 proteins and is larger than other known viruses, estimated to be about 600 nanometers in diameter. Since its discovery, scientists have speculated that its size and complexity are strong indicators that the Gokushovirus is the oldest known virus to exist.
Scientists have also speculated that it might have come from outer space, as it does not seem to have an earthly origin. This mystery remains unsolved, but scientists hope that continued study of the virus will give us insight as to how ancient viruses evolved.

When was the first human virus?
The exact origin of the first human virus is unclear and is thought to have arisen from a zoonotic source. It is believed that the first virus to infect humans was probably mouse leukemia virus, which was discovered in 1934.
This virus was originally identified as the cause of a lymphoid leukemia in mice, and it was later found to have a similar effect on humans. In the decades that followed, many other viruses have been discovered to be capable of infecting humans.
These viruses are typically divided into five distinct families: Picornaviridae, Retroviridae, Herpesviridae, Orthomyxoviridae, and Paramyxoviridae. While the exact date of the first human virus is unknown, the majority of scientists believe that the first human virus arose long before humans appeared on earth.
What was the deadliest prehistoric virus?
The deadliest prehistoric virus which is thought to have existed is believed to be the Prehistoric Marburg virus. This virus is thought to have been in existence for many thousands of years, with fossilized remains suggesting it existed in ancient insects.
This virus is believed to be related to the Marburg virus which is active in Africa today, and is believed to be one of the most virulent and deadly viruses in the world. The Prehistoric Marburg virus is thought to have been responsible for many deaths including the death of Napoleon in 1821, and the death of Tsar Alexander I in 1825.
The virus was also associated with several mass deaths during the Plague of Justinian in the 6th century AD. This virus, along with the common ancestor of all Orthopoxviruses (including smallpox), is thought to be one of the deadliest prehistoric viruses of all time.
Who first invented virus?
The first recorded incidence of a computer virus was in 1971, when a high school student in England, named Richard Skrenta, created a virus called “Elk Cloner. ” It targeted Apple II computers, which were extremely popular at the time.
The virus spread through floppy disks and ultimately prompted the user to show a poem written by Skrenta. Although it did no harm to the user’s files, it was the first documented malware. It wasn’t until the mid-1980s that computer viruses were commonly seen, with the growth in popularity of personal computers, driven largely by IBM.
It is not known who invented the first computer virus, as it is difficult to trace the history of a malicious program. However, it is widely believed that the first documented evidence of a computer virus called “The Creeper” was found in 1971 by Bob Thomas.
The Creeper was transmitted through ARPANET (the earliest form of the internet). It would copy itself to other computers, then send a message stating, “I’m the creeper, catch me if you can!”.
Did the 30 000 year old giant virus come back to life?
No, the 30,000-year-old giant virus did not come back to life. In 2003, a team of researchers from France discovered fragments of the virus, which they called “Pithovirus sibericum”, in samples taken from permafrost in Siberia.
The specimens were found to be perfectly preserved and were estimated to be about 30,000 years old.
Since then, a number of laboratory experiments have been conducted in an attempt to revive the virus, but without success. Despite being able to detect some of its genetic material, the virus has not managed to replicate itself and has not become active again.
It is thought to be a precautionary measure that the virus has taken to protect itself, as it entered a ‘cryptic’ or dormant state when triggered by an unknown signal, possibly a lack of nutrition or even compression by its icy surroundings.
Overall, while highly fascinating, the virus remains ‘dead’ and inactive, so in an answer to the question: No, the 30,000 year old giant virus did not come back to life.
What virus is 30.000 years old?
30. 000 years old is a very long time, and it is difficult to identify a specific virus that is of this age. However, a virus that is believed to be around 30. 000 years old is the Human Endogenous Retrovirus-K (HML-2) virus.
This virus is believed to have been passed down through the generations, and is found in certain individuals. It is thought to have been around since before the time of Homo sapiens, and is thought to have evolved over thousands of years.
It is believed that many of the diseases that we face today stem from this virus, as it has had millions of years to mutate and adapt. It is difficult to pinpoint the exact age of this virus, but based on studies of its genetic information it is believed to be around 30.
000 years old.
Can humans get giant viruses?
Yes, humans can get giant viruses, also known as giant virions or megaviruses. These viruses are significantly bigger than other viruses, with some measuring up to 1 micron (one millionth of a meter) in size.
The largest viruses known to infect humans are poxviruses, and humans can also become infected with other giant viruses, such as the Mimivirus, Megavirus chilensis, and Pandoraviruses.
Giant viruses were actually first isolated in the early 1990s, when they were discovered to cause viruses in amoebae. In 2003, the first giant virus was isolated from a human patient and since then, several more have been discovered.
There is evidence that giant viruses may be linked to some diseases, including a suspected link to chronic fatigue syndrome. However, much more research is needed to confirm this link. In general, giant virus infections are rare and most people who become infected with one usually remain asymptomatic.
In summary, whilst humans can get giant viruses, most infections tend to be asymptomatic and the role of these viruses in human health remains largely unknown.
When was virus first discovered?
The first virus discovered was the tobacco mosaic virus (TMV). This virus was discovered by a Russian botanist named Martinus Beijerinck in the late 1890s. TMV is a type of RNA virus, meaning it contains a single-stranded RNA genome inside an icosahedral-shaped protein capsid.
It primarily affects tobacco plants, causing their leaves to become flecked with brown patches. Since its discovery, many other viruses have been identified which have different shapes, sizes, and genetic materials.
Today, the environment is a much different place and many new viruses have been identified and studied to understand the way they infect and affect their hosts.
How did the first virus start?
The origins of computer viruses date all the way back to 1971, when Bob Thomas, a researcher at BBN Technologies, created the “Creek” virus. This virus was not malicious, however, and was instead intended as a playful experiment to demonstrate how a self-replicating program could travel across a network of computers.
Thomas’s virus was not malicious in nature and was manually launched and intended to affect only computers owned by BBN Technologies, which did not trigger any alarm bells for security.
The first malicious virus was written in 1986, known as the “Brain” virus. It was written by two brothers, Amjad and Basit Farooq Alvi, and was designed to be an anti-piracy measure on their medical software.
It would hide itself on a system, clone itself onto a floppy disk, and spread itself to other systems. Additionally, it would damage and corrupt the boot sectors of floppy disks, making them unable to boot in DOS due to it deleting important files.
This allowed the brothers to identify pirated copies of their software, as they would not have either the virus or the deleted files.
The Brain virus was the first known malicious virus, and inspired a wave of copycat viruses in the years that followed. Today, viruses and malware are a constant threat in the digital world, and antivirus software has been created to combat these threats.
Who created first virus?
The first computer virus, known as “Creeper system” was created by Bob Thomas in 1971. The Creeper System was a program that would move from computer to computer and display “I’M THE CREEPER: CATCH ME IF YOU CAN”.
It was the first computer virus that was able to replicate itself on other computers and had the ability to become a nuisance. However, the virus wasn’t malicious in any way and didn’t have any detrimental effects on computers.
This virus caught the attention of Ray Tomlinson, who leveraged the Creeper System’s code to create the first “worm” program in 1974. This one-step ahead program had single components for a virus—being able to propagate itself if given access to the right data path—and was more disruptive than its predecessor.
How did microbiologists know viruses existed before 1930?
Before the 1930s, microbiologists did not have the knowledge, technology or tools to identify viruses, and even harder to prove their existence and classify them. However, there were some clues that suggested the presence of viruses, even before the work of Stanley, Stanley and Wendy in 1933.
The first major hint was during the 1880s, when scientists began to recognize the role of microorganisms in disease. Scientists at the time were convinced that microbes or bacteria were the sole cause of many different infections and illnesses.
In the late 19th and early 20th centuries, some scientists noticed that certain diseases were not caused by bacteria and were not passed through physical contact like germs, leaving the potential for a mysterious agent to be involved.
In the early 1900s, researchers noticed that some diseases could be transmitted through filtered air, suggesting a mysterious particle was involved. This prompted further research, including the discovery of a ‘filterable agent’, which was later identified as a virus.
However, scientists still lacked the technology to prove their existence and classify them. It was not until the 1930’s, with the development of electron microscopes, that viruses were definitively proven to exist.
What giant virus was found in ice?
The newly discovered giant virus, Pithovirus sibericum, was found in ice in the Russian tundra. This virus is the oldest virus to have been discovered, estimated to have lain dormant in the icy depths for up to 30,000 years.
This virus is considered a “giant” because it has a larger than normal genome, with 1. 5 million base pairs of genetic material, more than twice that of other viruses.
This virus belongs to a family of viruses known as Mimiviridae, which are distinctive because they possess the double-stranded DNA of a traditional cell. Though many microscopic organisms had previously been discovered in similar environments, this is the first viral discovery of this type.
What makes this virus even more interesting is that much of the genetic material found in it appears to be similar to human DNA. In fact, it is estimated that about 10 percent of the virus’s genome is common to humans, which suggests that giant viruses may have some evolutionarily shared characteristics with us.
Overall, the discovery of Pithovirus sibericum has provided scientists with a unique insight into the evolution of viruses and opened the door to further study and understanding of the long-term possibilities of potential “extremophiles” living in extreme environments.
What virus almost destroyed the internet?
The Melissa virus is one of the most widely known and destructive computer viruses in history that almost destroyed the internet. It was first discovered in March 1999 and spread rapidly, infecting over 100,000 computers in just a few hours.
Despite its small size, the virus had far-reaching consequences, resulting in widespread system, network, and email shutdowns.
The Melissa virus was propagated as an attachment, typically called something like “list. ” Opening that file would launch a script that exploited vulnerabilities in Microsoft Office to mass mail itself to email addresses found in the user’s address book, spreading like wildfire across the internet.
It also effectively disabled any software that relied on Word files, including Outlook, leading to many system instability issues.
Companies, government organizations, and other services across globe struggled to contain the virus and prevent its further spread. It caused an estimated $80 million in damages as many businesses had to shut down operations for days and other organizations’ networks were severely taxed by the massive numbers of infected emails that kept being re-sent.
That being said, the Melissa virus did not end up destroying the internet, but it was a serious wake-up call to those responsible for PC security. It clearly demonstrated the power of the internet to propagate malicious code quickly and effectively, and it highlighted the importance of taking the necessary steps to protect computer network systems.
What type of virus is ILOVEYOU?
ILOVEYOU is a computer virus that was first released in the year 2000. It is classified as a type of malware, specifically a worm or a trojan worm. It spreads by sending copies of its virus code through email attachments.
After a user opens the attachment, the virus then begins to spread. It is classified as a malicious computer program because it disrupts computer operations and can delete or corrupt computer files. In addition, it can be used to gain access to a user’s personal information and accounts.
It is also considered to be one of the earliest and most wide-spread types of computer viruses that were released directly via email.
