All cellular life as we know it today stems from a single common ancestor, from which all modern lineages emerged. The origin of cellular life is thought to be the node in the Tree of Life from which Archaea and Bacteria, the two primary domains, diverged. The universality of some features across cellular life evidences […]
Author: María Martinón-Torres, CENIEH Director, Atapuerca Research Team and author of “Homo imperfectus” (Ed. Destino), Centro Nacional de Investigación sobre la Evolución Humana (CENIEH) The research team at the Atapuerca archaeological sites in Burgos, Spain, has just broken its own record by discovering, for the third time, the oldest human in Western Europe. The team […]
Scientists believe individuals of the most recently discovered hominin group (the Denisovans) that interbred with modern day humans passed on some of their genes via multiple, distinct interbreeding events that helped shape early human history. In 2010, the first draft of the Neanderthal genome was published, and comparisons with modern human genomes revealed that Neanderthal […]
The evolution of the human being has a complex form in which some branches bifurcate and form two different species and some different branches come together again and form individuals with a certain degree of hybridization. The only hominin remaining today is Homo sapiens and the last to disappear was Homo neanderthalensis. Neanderthals, our closest […]
Imagine this: you’re visiting the chimpanzee enclosure at a zoo. Some sit on the grass, chewing on leaves and scratching their heads, while others hang from the wooden beams. In a corner, a female is holding her baby. You can’t help but picture a human mom doing it in the exact same way. For a […]
We, humans, have evolved pretty big brains compared to other mammals, and even compared to our primate cousins. Recent research seems to have found the reason for the higher number of neurons in our brains (about 86 billion). It appears that a single gene is responsible for our bigger brain. The Neanderthals are an extinct […]
How did the complex organisms on Earth arise? This is one of the big open questions in biology. A team of researchers has come a step closer to the answer. The researchers succeeded in cultivating a special archaeon and characterizing it more precisely using microscopic methods. This member of the Asgard archaea exhibits unique cellular […]

Are we alone in the universe? This is a question that has intrigued humans for centuries and inspired countless studies and works of fiction. But are we getting closer to finding this out? Now that the James Webb Space Telescope (JWST) is in operation, we might have taken one giant leap in being able to […]

An Earth-like planet named GJ 1252b orbiting an M dwarf — the most common type of star in the universe — appears to have no atmosphere at all. This discovery could cause a major shift in the search for life on other planets. Because M-dwarfs are so ubiquitous, this discovery means a large number of […]
The patriarchy, having been somewhat in retreat in parts of the world, is back in our faces . In Afghanistan, the Taliban once again prowl the streets more concerned with keeping women at home and in strict dress code than with the impending collapse of the country into famine. And on another continent, parts of […]
