1 Trillion Species, 3 Billion Years: How to Track the Evolution of Bacteria on Earth using AI
Credit: CC0 Public Domain There are about 1 trillion species of microorganisms on Earth. Most of it is bacteria. Bacteria are made up of a single cell. They have no bones and are not like large animals that leave clear signs in the geological records. This is something paleontologists who appreciate it in a few million years can study. This…

Scientists uncover key mechanisms in evolution: Whole-genome overlap promotes long-term adaptation
We have evolved macroscopic “snowflake” yeast from multi-tee experiments. Large sizes of nuclei (yellow) and cell (cyan) are the result of whole genome overlap and aneuploidy. Credit: Georgia Institute of Technology Sometimes the most important scientific discoveries happen by chance. Scientists have long known that whole-genome overlap (WGD) (the process by which an organism copies all genetic material) plays an…

Mars Time Machine: Researchers create a virtual model to decipher the climate evolution of the Red Planet
Credit: CC0 Public Domain Researchers are creating sophisticated simulations that will help you understand Mars’ climate history better and help you determine whether it can once be a life-sustaining experience. An international team of researchers is developing a model of Mars’ evolution that can unlock some of the secrets of many years, including whether they once had life. François, a…

Giant Ice Bulldozer: How Ancient Glaciers Helped the Evolution of Life
Ancient glaciers formed the surface of the Earth, paving the way for complex life. Credit: Chris Kirkland A new study from Curtin University revealed how giant ancient glaciers behave like giant bulldozers, remake the surface of the Earth, paving the way for complex life to flourish. The study entitled “The Neoproterozoic Glacial Broom” is published in Geology. By chemically analyzing…

Does the evolution of planets support human-like lives? Study the odds of ups that we are not alone
The new model overturns decades-old “hard step” theory that intelligent life is an incredibly unlikely event, suggesting that it was not that difficult or impossible. The team of researchers said a new interpretation of human origin would increase the probability of intellectual life elsewhere in the universe. Credit: NASA Humanity is not extraordinary, and rather, according to a new model…

Wearing Covids and Masks Outdoors: How Culture and Evolution Shape Our Behaviors
The willingness to wear outdoor masks during the Covid-19 pandemic was dependent on a variety of factors. Credit: Rebecca Haan, University of Tebingen An international research team led by Christophe Rander, a professor of biology education at the University of Tübingen, has revealed that people in collectivist societies like Japan have been involved in such individualistic countries during the Covid-19…

Possible evidence of avian influenza vaccination promoting virus evolution
Temporal dynamics in the divergence and adaptive fixation of H5 AIV HA genes in different host-specific lineages. Credit: Science Advances (2025). doi:10.1126/sciadv.ado9140 A team of virologists, infectious disease experts, and pathobiologists from several institutions in China and the United Kingdom has found possible evidence that avian influenza vaccination is accelerating the evolution of the virus. In their study published in…

Fossil discovery sheds light on the early evolution of animal nervous systems
An incomplete tubular specimen of the Eopliaprites sphinx excavated from the Quang Tuanh Formation of the Early Cambrian. The ventral nerve cord is shown. Credit: Science Advances (2025). DOI: 10.1126/sciadv.adr0896 An international team of scientists has solved a fascinating piece of the evolutionary puzzle. That’s how the ventral nerve cord, a key component of the central nervous system, evolved in…

Comprehensive analysis reveals hidden genome evolution of brown algae
Characteristics of ecology, diversity, and evolution of brown algae. Credit: Cell (2024). DOI: 10.1016/j.cell.2024.10.049 Covering more than 70% of the Earth’s surface, the oceans are home to countless life forms that maintain ecological balance and support human well-being. Among these, brown algae (Phaeophyceae) play an important role in maintaining coastal habitats, supporting marine biodiversity, and combating climate change through carbon…

Morphological studies reveal the evolution of diverse jaws in lizards and snakes
An image of an anole (a type of “false chameleon”) crushing a snail with its jaws. Credit: Professor Anthony Herrell Research from the University of Bristol shows how lizards and snakes, the most diverse group of land vertebrates with around 12,000 species, evolved an astonishing variety of jaw shapes and are an extraordinary ecological success. clarified what brought about this.…
