The first known computer virus, called “Elk Cloner,” was discovered by 15-year-old Rich Skrenta in 1982. Spread through Apple II computers, the virus was designed to circulate through floppy disks. When a person ran a disk infected with Elk Cloner, the virus would copy itself to the computer’s memory, where it would execute its payload—displaying a short poem written by Skrenta every 50th time the user booted the computer.
At the time, Elk Cloner was mainly a nuisance, but it was the first example of malicious computer code that could spread on its own, thus making it historically significant.
Who is father of virus?
The answer to this question is not completely straightforward, as the concept of a “virus” is a broad and intangible one. In the most general sense of the term, “virus” can refer to any infectious agent that is transmitted from one living organism to another.
While there is no single individual who can be said to be the “Father of Viruses,” scientific discoveries over the course of the 19th and 20th centuries ultimately paved the way for our current understanding of viral infections.
In 1892, Dimitri Ivanovski proposed the concept of viruses for the first time, noting discovered differences in tobacco mosaic disease, which would later be found to be caused by a virus. However, it wasn’t until 1939 that cancer-causing viruses were successfully discovered by Joe rgared, who identified Rous sarcoma virus (RSV).
Following this discovery, researchers began to understand better the life cycles, genetics, and structure of viruses, leading to the initial theories of virulence and modulation. In the same decade, the concepts of lysogeny and temperate phages were developed, which had tremendous implications for our understanding of how viruses can spread among a given population.
Ultimately, the development of vaccine technology in the mid-20th century allowed for our modern ability to combat and prevent the spread of numerous serious diseases. While focusing on the development of effective vaccines, scientists also worked to further refine their understanding of virus and virus behavior, leading to current state of the art research that continues to evolve our knowledge of virus biology.
Given the cumulative nature of scientific progress, it is difficult to attribute the concept of or discoveries related to viruses to an individual. Therefore, while no single person can be called the “Father of Viruses,” numerous scientific breakthroughs, crucial discoveries, and technological advances made since Dimitri Ivanovski’s initial observations have had a profound, and lasting, impact on our modern understanding of viral infections.
Who first released virus?
The exact origin of the first computer virus is unclear but it is believed to have been released in the early 1980s. It is widely accepted that the first virus, which was called “Elk Cloner,” was released in 1982 and targeted Apple II computers.
The virus was written by a high school student in the United States. It would attach itself to Apple boot sector and spread from one Apple II computer to another. It is also known as the first self-replicating computer virus.
Subsequent viruses have evolved in complexity, with some incorporating features designed to make them more difficult to remove.
Who had discovered the virus?
The novel coronavirus was first discovered in 2019 in Wuhan, China. Initially, the virus caused an outbreak of respiratory illness that was later identified as coronavirus disease 2019 (COVID-19). Scientists from the Chinese Center for Disease Control and Prevention (CDC) were the first to detect the virus and shared their findings in a paper published in the New England Journal of Medicine on January 10, 2020.
The World Health Organization (WHO) then activated an international response to the virus. The genetic sequence of the virus was shared, allowing scientists around the world to research and study the virus.
Researchers then identified that the virus was a new coronavirus and named it SARS-CoV-2.
The source of the virus has not been conclusively identified, but the prevailing view is that it originated in animals and was spread to humans. It is possible that the virus was spread at a seafood market in Wuhan, where people interacted with animals that were carrying the virus.
Which came first man or virus?
The answer to this question is not straightforward, as there is no single, definitive answer. While viruses existed before humans on Earth, there is evidence that suggests both viruses and humans evolved from a common ancestor.
The oldest known virus is believed to have originated billions of years ago, before there were any humans on the planet. Scientists believe that viruses must have been on Earth longer than any living organism, as they can replicate in non-living environments like the soil.
This means that viruses are likely to have been the first of any organism to exist on Earth.
However, other evidence points to a more ancient ancestor that evolved both viruses and humans. This evidence suggests that a common ancestor created both viruses and humans, so it is impossible to say which one come first.
In short, while scientific evidence suggests that viruses existed before humans on Earth, it is impossible to definitively determine which one came first.
How long have viruses existed?
Viruses have likely been around since the very early stages of life on Earth, over 3. 5 billion years ago. However, it wasn’t until the 1900s that scientists were able to identify and study viruses. In 1892, Dmitri Ivanovsky, a Russian scientist, discovered what is now known as the Tobacco Mosaic Virus – the first virus ever to be identified.
Prior to this, many illnesses and diseases were believed to have been caused by bacteria or fungi, rather than viruses. From the 1950s to the present day, we have seen a large increase in our understanding of viruses, with so much of this understanding thanks to the advancements in modern technology such as electron microscopy.
Today, viruses are studied in a great detail, allowing for a much better understanding of how they invade and damage cells and how to fight them.
Are humans a virus?
No, humans are not a virus. Humans are an advanced species that have evolved over millions of years. They have built and maintained complex societies and civilizations, created art, literature and music and have an advanced understanding and appreciation for the beauty of the environment.
Humans have an innate ability to learn, adapt and innovate.
Viruses, on the other hand, are tiny, often single-celled, parasitic organisms that are only capable of replicating themselves, using the cells of a host organism to do so. They lack the complexity and sentience of human beings, and instead rely solely on their ability to spread and infect cells in order to survive.
Thus, while humans and viruses are both able to replicate, their complexity and functionality are vastly different.
Which virus is related to coronavirus?
Coronaviruses are a family of viruses that are related to one another and can cause a range of illnesses, ranging from the common cold to more serious diseases like Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS).
Coronaviruses are particularly common in animals, but some, such as the SARS and MERS viruses, have jumped from animals to humans and caused epidemics. The virus responsible for the current coronavirus (COVID-19) pandemic is a novel coronavirus that has not been previously identified in humans.
It is believed to have originated in bats, then jumped to another animal (possibly a pangolin) before infecting humans.
When did virus first appear on Earth?
The exact origin and earliest evolutionary history of viruses remain unclear, though there are a few theories and indications that they have been present on earth since ancient times. Archaeological evidence suggests that viruses have been around since at least the Bronze Age, around 5,000 to 4,000 years ago.
Viruses may have even been around even longer, since many ancient viruses are thought to have been absorbed into the gene pools of various organisms, meaning they may have been around long before there was any archaeological evidence to show for it.
Viruses are believed to have been around for much of Earth’s history and are an inherent part of the natural environment, such as in the biome of aquatic life. It has been theorized that these ancient viruses were responsible for many of the pandemics and other outbreaks in history, though this is difficult to confirm given the lack of archaeological evidence from such ancient times.
What is known is that the first documented record of the occurrence of the virus occurred in the 16th century, during the influenza pandemic of 1580. The virus was discovered and identified in the mid-19th century, when Louis Pasteur and Robert Koch formed the basis of microbial scientific study.
Since then, viruses have been studied in greater detail, allowing us to understand and develop treatments for a variety of virus-based diseases.
Are we born with viruses in our bodies?
No, we are not born with viruses in our bodies. While some viruses do pass to a fetus while in the womb, they are not part of the baby’s natural biology and do not stay with the child after birth. For example, babies can be born with the herpes virus if they contract it through their mother, but as soon as they leave the womb, the virus leaves their body.
However, it is possible for a person to have some viruses located in their cells due to a process called retrotransposition. Retrotransposition happens when a person’s DNA incorporates a virus’s genetic code.
It is not considered an infection, since the virus does not replicate or cause active infection. Instead, these viral particles remain inside the person’s cells, integrated into their chromosome. This happens in all humans from time to time, and while it is a normal part of the body, it is not considered something we are born with.
Did life come from viruses?
The origin of life on Earth is a highly debated subject, and while there is still much to be explored and understood on the topic, research has yet to definitively suggest that life came from viruses.
While viruses do contain genetic material, they are incapable of independently replicating; they must use an existing host to reproduce. As such, it is difficult to place viruses at the beginning of the evolutionary chain.
Some have proposed that viruses may have assisted in the evolution of early life forms, acting as a driver that helped organize the original cellular components. Some experts believe that viruses and other components may have existed together in what are termed protobionts: simple combinations of components that would eventually become organic cells and self-replicate.
However, this has yet to be fully corroborated.
Ultimately, there may be many pieces of this puzzle yet to be discovered and researchers will continue to investigate the possible sources of life on Earth for many years to come.
What virus does everyone have?
The virus that everyone has is called a human coronavirus, which is a type of virus that affects the respiratory system. Coronaviruses are single-stranded RNA viruses that cause a variety of illnesses ranging from the common cold to more severe diseases such as acute respiratory syndrome (SARS).
These viruses cause inflammation of the airways and can lead to various symptoms such as coughing, sneezing, runny nose, and sore throat. In some cases, these infections can be severe and may even lead to hospitalization and even death.
The most common coronavirus is called the Novel Coronavirus, or COVID-19, which has caused a severe global pandemic since its outbreak in December 2019.
Are viruses alive Yes or no?
No, viruses are not alive. While the term “alive” is often used loosely to mean anything that exhibits some level of action or activity, in a scientific context, viruses do not meet the criteria for being alive.
Viruses do not have the properties necessary for life, such as the ability to grow, reproduce, or sustain many of the chemical processes that occur in living organisms. Viruses also do not possess any cellular structure, which is a necessary characteristic of life, and instead consist of a collection of genetic material encased inside a protective protein coat.
In sum, viruses are not living organisms, and therefore are not considered alive.
What percent of human DNA is virus?
When looking at the total amount of human DNA, only a very small percentage is actually made up of viruses. According to the Human Genome Project, only around 8% of human DNA is made up of endogenous retroviruses, which are remnants of ancient viral infections.
This number is only an estimate though, as it varies slightly from person to person. Outside of these endogenous retroviruses, research suggests that there are very few known virus-derived elements in the human genome.
Do viruses grow or develop?
No, viruses do not grow or develop in the same way that other forms of life, such as animals and plants, do. Unlike cells that can reproduce, viruses must use the mechanisms of other living organisms in order to replicate and spread.
Viruses invade cells of other organisms and take over their machinery to create copies of themselves. This process of viral replication is not considered to be growth or development in the same way that other forms of life do, as viruses do not contain the necessary components for self-replication that would be found in other forms of life.
