Scientists They did an extremely rare feat: they saw a microbe the legend of louisa. This microscopic object, discovered in 1908, is so hard to find that it is more likely to travel to the moon than to see it. a study More than 500 microorganisms were also observed.
By studying each DNA sample collected, researchers piece together the puzzle of evolution and strive to unravel how an organism functions. For example, some genes indicate how an organism breathes; Or it can give information about that organism’s position in the taxon (the tree of life). There is a myriad of other information that these microorganisms can provide.

To find these microbes, the team took two years and sent more than a thousand samples for examination this time. Search. In general, those who conduct research using this type of sample have low variance in sample groups, that is, they focus on a few or even only one site. Lakes and ponds were inspected in Warsaw, Poland; marine sediments in the North Sea and the Mediterranean Sea off the coasts of Italy and Portugal; and chalk tables in Dorset, UK. More than 500 species have been found, including rare and new ones.
Although they are abundant and very ancient, science knows very little about these little creatures. It is worth noting that microorganisms were the first predators on Earth and thanks to them life as we know it today was able to flourish. It was they who spurred a single evolution in the early ages of Earth’s history. Like all living things, they are also part of the food chain, and their disappearance can cause serious ecological disruption.
When looking at the tree of life, you can see how known living things are related to each other, and how microbes make up most life on Earth. a loyezae It is a single-celled ciliated microorganism that is part of the domain of Eukarya, that is, eukaryotic organisms (they have a cariotheca, the membrane that separates the cell nucleus from the cytoplasm). For this ciliate, oxygen is fatal, so it lives in an aquatic environment, with little oxygen. Many microbes create capsules to protect themselves from hostile environments for their own survival.
Microorganisms are essential to life on Earth
The diversity within this group is enormous. While some enjoy an active life, others enjoy a sedentary lifestyle. While some live together, others lead a solitary life, which makes the search for certain species more difficult. Each one has its own peculiarity, which makes these creatures unique.
It would be impossible to live without microbes, they are ultimately responsible for the survival and restoration of our ecosystems after damages such as pollution or climate change. Food cannot be grown without microorganisms. They clean the sewers. Some are involved in the production of antibiotics and other medicines. In short, many essential applications for survival.
