A team led by Dr. Svengurd, an evolutionary biologist at the University of Heinrich Heine University of Düsseldorf (HHU), is studying the current state of research on land plant colony formation that took place about 500 million years ago. The results of this illustrated summary study, published by Dr. Monashriver as lead author, have been published in the latest issue of the journal. Trends in plant science..
Since the formation of the earth about 4.5 billion years ago, the initially fiery earth has cooled, and the first sea Land To the application form. For the next 3 billion years, the land was barren rock.
The blue planet with the green continent we know today did not exist that way at that time.Continental conditions are primarily life-threatening, with much higher volcanic activity releasing toxic gases into the atmosphere and weaker magnetic fields exposing more land than currently exist. Cosmic raysAnd a thinner ozone layer for filtering UV light.
This began to change about 500 million years ago when plants began to colonize the land. Invasion catalyzed hostile environmental transformations, accelerated atmospheric changes, and, as we know today, laid the foundation for the development of life on land. All this can only occur when plants that lived only in sea and inland freshwater conquered the continent.
Currently, Professor Sven Gould and Professor Stefan Rensing of the Institute for Molecular Evolution of HHU, and Dr. Mona Schreiber, a bioinformatics expert and artist at the University of Marburg, are presenting the journal’s land plant colonization. Trends in plant science..
The continent turns green in a process with many molecular and morphological adaptations, after the streptophytic algae have moved from aquatic habitats to coastal areas and before they completely migrated to land more than 500 million years ago. It has begun to change. Through the ongoing changes of the earth, plants show tremendous adaptability, mainly carbon dioxide (CO).2) On a large scale.
Terrestrial plants spread with a predominant tour force, and flowering plants proliferated explosively. Today, they account for over 90% of all known terrestrial plant species.In the history of our planet, land plants have caused some Climate changeShows tremendous adaptability over and over again.
Researchers are studying the genomes of evolutionarily important species of terrestrial species, such as moss, lycopods, ferns, and certain algae, to gain a better understanding of evolutionary processes and molecular adaptation. Their work aims to identify mechanisms that have helped to alleviate the hostile living conditions of the land that have changed over the course of this evolution.These may prove to be relevant for sure Climate changeIncludes crop modifications according to changing environmental conditions.
Regarding the role of humans in the evolution of planets, Professor Gould, a senior author of the study, explains: The extreme speed of these changes causes major problems, as nature has little time to adapt. Humans develop agriculture, LivestockIn this work, the co-author analyzes the effects of humans on climate and discusses the adaptability of plant life to the changes that are unfolding today.
