The oldest known virus on earth is the ATCV-1 virus, which is a microsporidian virus first discovered in 2015 in the Amoebophrya sp. thermophila microalgae species. This virus was genetically tested to be roughly 1.
5 million years old, making it the oldest known virus to date. ATCV-1 belongs to the family Microsporidia, which are intracellular parasites that infect eukaryotic cells. ATCV-1 was isolated from a sample of a single-celled alga in the Mediterranean Sea, and its presence was confirmed using state-of-the-art genetic sequencing.
This virus infects cells by driving them to produce multiple copies of itself, which then burst out of the cells, thus releasing new viral particles into the surrounding environment.
ATCV-1 is believed to be one of the earliest surviving species of viruses on the planet, and further research suggests that it is likely to be responsible for a number of unknown illnesses and diseases.
Its age and longevity indicate that it has already adapted to various environmental changes and is therefore capable of adapting to new conditions in the future as well.

What is world deadliest disease?
The world’s deadliest disease is probably HIV/AIDS – it has caused the most deaths in the world, with an estimated 36 million people having died from it since its discovery. HIV/AIDS is an incurable virus, and has caused an estimated 78 million infections worldwide since its discovery.
It continues to impact people around the globe, with an estimated 37. 9 million people currently living with HIV. It is spread through the exchange of bodily fluids, primarily through unprotected sex and birth from an infected mother.
This virus attacks the immune system, and makes it harder for the body to fight off infections and illness. HIV can be prevented through the use of condoms, staying in a faithful monogamous relationship and not sharing needles for drug use.
Treatment for HIV is now available and has drastically improved the quality of life for those living with the virus. Unfortunately, even with today’s treatments and prevention methods, HIV/AIDS continues to be one of the world’s deadliest diseases.
Which came first man or virus?
The answer depends on which type of virus you are asking about. The first viruses may have been bacteriophages, which are viruses that were derived from primitive bacteria. These viruses likely existed prior to the emergence of modern humans, so technically they came before man.
However, since viruses are made of genetic material and man is made of biological material, the emergence of one did not necessarily coincide directly with the emergence of the other.
More recently, human-made viruses such as the common cold virus and the HIV virus have come into existence only within the last century or so. Therefore, these viruses clearly came after man, since man was necessary for their invention.
Who created viruses?
It is impossible to definitively answer who created viruses, as viruses have been around for centuries before modern science was able to study them. It is likely that viruses originally arose spontaneously as part of the Earth’s natural environment, as evolutionary biologist Lynn Margulis hypothesized in the 1970s.
This hypothesis is supported by the fact that despite our best efforts, viruses continue to evolve and mutate, leading many to believe they are “alive” or at least partially organic.
It is estimated that most of the viruses today (including those with pandemics potential, like SARS-CoV-2 and HIV) had their origin in ancient times. However, in recent decades, humans have had a major contribution to the increasing number of viral species.
This is because researchers, who are increasingly using more complex and powerful tools, have been able to create whole new viruses, as well as modify existing ones. It is also possible for viruses to be spread through contact with animals, and even from food, technology, and the environment.
Overall, it is impossible to have a definitive answer for who created viruses. In some cases, it is natural selection that is responsible, but more often than not a combination of both emerging technology and chance have been the cause.
What came before viruses?
Before viruses, cellular life forms existed as primitive cellular organisms, such as bacteria and archaea. These single-celled organisms interacted with each other in environments such as oceans and deserts.
Over time, certain genetic components of some of these organisms began to transfer to other cells, leading to the evolution of viruses.
In essence, viruses have no known precursor. Rather than having their own origin, viruses likely developed from parts of primitive cellular organisms. Specifically, it is hypothesized that viruses evolved from genetic components of once-living cells.
It is believed that when some viruses first began to form, they were benign and did not cause any harm to their host cells. Over time, however, certain viral components came to favor successful replication within the host cells, leading to the spread of viruses to other organisms.
This gave rise to the viruses we know today.
Did viruses create humans?
No, viruses did not create humans. Humans evolved from primates millions of years ago and are classified as Homo sapiens, the only extant species in the Homo genus. Though viruses can effectively manipulate the cells in our bodies, they appear to have had no direct involvement in the evolution of human beings.
Viruses, like all other forms of life, may have altered the environment of our ancestors in ways that constrained their evolution or pushed it in new directions; however, viruses do not have the capability to actively create new species such as humans.
Viruses are obligate intracellular parasites that are adapted to reproduce by hijacking the machinery of the host cell. By contrast, humans reproduce through meiotic sexual reproduction, meaning that they create a new individual by combining their genetic material with that of another individual of the same species.
When did the first diseases start?
The earliest recorded cases of diseases date back to ancient times. The first recorded outbreak of disease started in Egypt in 3,000 B. C. when an epidemic of malaria struck the population. From then on, diseases have been documented throughout history in various parts of the world.
Early writings from China as far back as 1,600 B. C. detail symptoms and treatments for various medical conditions. Other reports from ancient Greece and Rome indicate the presence of deadly diseases such as smallpox, influenza, and malaria.
By the 9th century, new cases of smallpox and the bubonic plague began to appear in Asia and Europe. In the 18th century, measles and tuberculosis began to spread throughout the world, claiming the lives of thousands of people.
As society and healthcare have progressed, so have the prevalence and treatment of diseases. Today, advances in medicine and public health have made it possible to prevent, diagnose, and treat many diseases.
Did early humans get sick?
Yes, early humans certainly did get sick. Even though our medical knowledge has a much greater depth nowadays, humans are still susceptible to the same ailments that plagued us on the evolutionary timeline.
Throughout history, humans have been affected by a variety of illnesses, both minor and life-threatening. For example, many ancient civilizations (like the Greek, Roman, and Egyptian Empires) held records of their citizens’ encounters with the common cold, flu, measles, malaria, smallpox, tuberculosis, and even the bubonic plague.
The Black Death killed around 50 million people in the 14th century alone. Additionally, archaeological evidence revealed in prehistoric sites showed how viruses, bacteria, and parasites also infected our distant ancestors and resulted in sickness or death.
Who is father of virus?
The father of the modern concept of viruses is generally acknowledged to be Frederick W. Twort, a British microbiologist, and Félix d’Hérelle, a French-Canadian microbiologist. Twort, in 1915, discovered a small agent that infected and destroyed bacteria in a petri dish.
He postulated that they were caused by an invisible living microorganism, which he called a bacteriophage or “bacteria eater. ” d’Hérelle, working independently in 1917, observed a similar “clear zone” in an agar plate.
He thought that this may be caused by the agents even smaller than bacteria, which he called “virus”. This coinage was followed in 1920 by French-American bacteriologist, Edwin L. Steinhardt, who proposed the term “virus” from the Latin word for “poison.
” The work of Twort, d’Hérelle, and Steinhardt form the basis for the modern understanding of viruses.
What is the only human disease to have been?
The only human disease to have been completely eradicated is smallpox. Smallpox was a contagious, sometimes fatal, viral disease that was caused by an infection with one of two virus variants, Variola major and Variola minor.
The last known case of smallpox occurred in Somalia in 1977, and in 1980 the World Health Organization (WHO) declared that the disease had been successfully eradicated worldwide. Vaccines developed in the late 18th century had played a major role in the fight against smallpox, and since its eradication, many other diseases have come close to the same fate.
