Last Universal Common Ancestor (LUCA)
- The Last Universal Common Ancestor (LUCA), the species from which everything alive today is descended, may live at this time according to genetic evidence. Attempts to reconstruct its genome suggest it lives in a volcanic or geothermal setting.

Aug 10, 2020 · A new analysis of the genomes of the most famous of ancient humans - Neanderthals and Denisovans - has revealed an as-yet-unidentified ancestor for our species – a branch of our distant family tree without any known label to put to it.

Genes, rather than fossils, can help us chart the migrations, movements and evolution of our own species—and those we descended from or interbred with over the ages. The oldest-recovered DNA of an early human relative comes from Sima de los Huesos, the “Pit of Bones.” At the bottom of a cave in Spain’s Atapuerca Mountains scientists found thousands...
As the physical remains of actual ancient people, fossils tell us most about what they were like in life. But bones or teeth are still subject to a significant amount of interpretation. While human remains can survive after hundreds of thousands of years, scientists can’t always make sense of the wide range of morphological features they see to def...
Our ancestors used stone tools as long as 3.3 million years ago and by 1.75 million years ago they’d adopted the Acheulean culture, a suite of chunky handaxes and other cutting implements that remained in vogue for nearly 1.5 million years. As recently as 400,000 years ago, thrusting spearsused during the hunt of large prey in what is now Germany w...
Many genetic analyses tracing our roots back to Africa make it clear that Homo sapiensoriginated on that continent. But it appears that we had a tendency to wander from a much earlier era than scientists had previously suspected. A jawbone found inside a collapsed caveon the slopes of Mount Carmel, Israel, reveals that modern humans dwelt there, al...

The timeline of human evolution outlines the major events in the evolutionary lineage of the modern human species, Homo sapiens, throughout the history of life, beginning some 4 billion years ago down to recent evolution within H. sapiens during and since the Last Glacial Period.
Oct 21, 2024 · human evolution, the process by which human beings developed on Earth from now-extinct primates. Viewed zoologically, we humans are Homo sapiens, a culture -bearing upright-walking species that lives on the ground and very likely first evolved in Africa about 315,000 years ago.
Stonehenge is at least 4,000 years old and still visible today, and monuments buried nearby could be even older. Most modern buildings aren’t that robust, but some traces would likely remain for at least 10,000 years, even if it was just the magnetic trace of the steel bars inside concrete blocks.
Feb 10, 2021 · Their new paper, published in Nature, reviews our current understanding of how modern human ancestry around the globe can be traced into the distant past, and which ancestors it passes through during our journey back in time.
Molecular evidence suggests that between 8 and 4 million years ago, first the gorillas, and then the chimpanzees (genus Pan) split off from the line leading to the humans. Human DNA is approximately 98.4% identical to that of chimpanzees when comparing single nucleotide polymorphisms (see human evolutionary genetics).
