New Research Shows Bacteria Exterminated at Higher Rates than Expected


The new theory shows that in the past million years between 45,000 and 95,000 types of bacteria have gone extinct.

Researchers have also discovered that bacteria resists mass extinction, hitting strong life forms such as dinosaurs.

Using state of the art technology scientists have discovered there are between 1.4 and 1.9 million different parentage bacteria.

The different mathematical structure found in DNA structures reveal the first tree for bacteria also with the rate of annihilation.

Dr. StilianosLouca the lead professor at British Columbia University said that studying patterns of evolution and eradication of bacteria could show how organisms survive.

Also noted that for up to 3.5 billion years “the geochemical composition of our planet has been shaped by the evolution and diversification of bacteria.”

“The Great Oxygenation Event was caused 2.35 billion years ago by cyanobacteria altered Earth’s surface environments and the evolution of life.”

“We know very little about the dynamics by which bacteria has shaped Earth’s history.”

He also said that “Sequencing and math helped us fill in the bacterial family tree, drafting how they varied in time and bring to light extinction.”

Even though some species have slowly but sure have been extinct, they’ve found that bacteria has been ascending without interruption.

Researchers have found using high power computers how bacteria have developed and evolved over time.

“Ten years ago, this study wouldn’t have been possible,” said Dr. Michael Doebeli, zoologist and mathematician.

“Using massive sequencing data and powerful computer programs allowed us to perform this mathematical analysis.”

Even so scientist had another challenge to account for the large numbers of undiscovered bacterial species to build the tree.

The study shows that they’ve used “sequencing data from 60 studies in diverse environments across the world” to measure the range of bacteria.

DrLouca suggested that findings from the last one billion years, show how extinction rates were mildly affected during mass extinctions which were seen in eukaryotic fossil records.

Eukaryotic cells are found in plants, fungi and animals.

In conclusion, he said that “our analysis explains how bacteria is diversified over geological time.”

“Evidence was found over the global bacterial diversity which increased over the past billion years.”

“Bacteria is the most ancient of all forms and these results have implication on how life unfolded over Earth’s history.”

Scientists are planning to study how the physiological properties of bacteria increase in time.

The study is published in Nature Ecology and Evolution.
