Scientists discovered LUCA, a single-celled organism thought to be the ancestor of life

Scientists have discovered a single-celled, bacterial-like organism that appeared on Earth 3.8 billion years ago and is believed to be the ancestor of life on earth. This bacterium is called the "common ancestor" of life on earth, or more fully, Luca - Last Universal Common Ancestor . The discovery of Luke will contribute to reinforce where and when the hypothesis of the origin of life originates.

It is thought that Luca appears near the vents on the seabed, while others argue that they are present in small ponds. Researchers began studying Luca by studying about 2,000 genes of today's bacteria, to understand the relevant origins between modern bacteria and Luca. If a relationship is found, it can be said that Luke is our ancestor, the source of all life on the earth today.

Single organism of Luca.

Luca is thought to have appeared on Earth since 3.8 billion years ago, which is the origin of the first two simple life forms in the world, including bacteria and ancient bacteria and later plants. and the animals. It also allows scientists to explore Luca's original 355 genes to learn more about this single-celled organism. Some theories suggest that at that time, lava erupted from the craters in the ocean had blown up Luca, spreading us the surrounding seawater, enabling life to form as it is today.

Sea-bottom vents are still thought to be one of the origins of life, and the discovery of single creatures from Luca reinforces this argument. However, it is also suggested that life on earth must be tested with harsh conditions, making them look for safer hiding places, possibly the above vents, for example, celestial cases The jelly falls to the earth.

Dr. William F. Martin of Heinrich Heine University in Germany said that by clearly locating the genes that Luca had, he hoped to find the answer to the question of how creature Luca lived. Dr. Martin described that the discovery of Luca would be the opposite of the hypothesis that life on earth was formed by a combination of chemicals, typically oxygen, hydrogen and nitrogen, which made organic compounds. muscle.
