Scientists have searched for the origin of life on Earth, and new findings from Yellowstone National Park could help explain that.
What was discovered in Yellowstone National Park?
Microbiologists discovered a new archaea line that lives in parts of Yellowstone National Park. This discovery will likely help scientists determine the origin of life on Earth and on other planets.
A study on the discovery was published on May 1
"The discovery of archaic lineages is critical to our understanding of the Earth's universal tree of life and evolution," write Professor William Inskeep of Montana State University and the co-authors. "Geochemically diverse thermal environments in Yellowstone National Park offer unprecedented opportunities to study archaea in habitats that could be analogues of early Earth."
The archaea are one of the earliest forms of cellular life on earth. This discovery may explain how it has evolved over time and how life on Earth has changed.
In particular, the archaea were discovered in the acid waters of Yellowstone. They do not need much oxygen and they thrive on iron oxides. Their discovery could explain how life on Earth thrives at a time when the chemical composition was different.
The researchers decided to name the new archaeological line Marschaewien after the planet Mars, because they can survive in habitats with iron oxides. These are the chemical compounds that give Mars its red color.
In addition to the name of the new archaeelic line, the researchers also identified two major subgroups that can survive in a habitat of iron oxide. The first subgroup can survive in water over 122 degrees Fahrenheit and the other subgroup can survive in water over 140 to 176 degrees Fahrenheit.
The researchers also found that the new archaeelle line can not produce iron oxide, throwing a little light on Earth's conditions billions of years ago.
The Importance of Archaea Discovery
This new discovery will help scientists connect the dots when it comes to high-temperature biology and molecular biology. It could provide important insights into early life on earth and early life on the Martian surface. More research will be needed to see the new implications.
It is unbelievable to researchers that their work will be published.
"In the end, after many years of work, it is exciting and a relief to recognize and publish the work of our team, especially in a powerful journal," said researcher Zackary Jay.
