The origins of domestic cats, and their travels with ancient humans, are as enigmatic as the animals themselves. But now, scientists have found new evidence supporting the idea that the unfathomable felines were likely first domesticated in ancient Egypt, where they were worshipped as part of a cult — or in another region of North Africa.
Researchers already knew that modern-day lap cats (Felis catus) derived from African wildcats (Felis lybica). But exactly when and where these wildcats first accepted human companionship is a matter of intense debate.
Now, two studies published on the preprint server bioRxiv in March 2025 — meaning they have not yet been peer-reviewed — offer tantalizing new insights into how the world's second-most-popular pet may have come to coexist with humanity and spread around the world.
One of the prevailing hypotheses is that cats were domesticated in the Levant, a region of the Middle East bordering the Mediterranean Sea, during the Neolithic period 12,000 to 5,000 years ago.
The region is part of the Fertile Crescent, where agriculture first emerged. The theory suggests that when humans switched from a hunter-gatherer lifestyle to farming, rodents became a problem. Cats were attracted to the rodents and, given the felines were eating the pests, humans were happy to cohabit with them.

This theory is based on the discovery of a cat buried at the foot of a human in Cyprus, which is off the coast of Turkey and Syria.
"The first evidence of human association with a cat comes from Cyprus about 10,000 years ago," Jonathan Losos, an evolutionary biologist at Washington University in St. Louis and author of "The Cat's Meow: How Cats Evolved from the Savanna to Your Sofa" (Viking, 2023), told Live Science. That suggested the cat-human association may have begun in the Fertile Crescent, said Losos, who was not involved with the new research.
But both of the new papers cast doubt on this idea, suggesting cat domestication actually took place much later, and that cat remains suggesting earlier interactions were actually wildcats.
In one of the news studies, the researchers conducted genetic analyses on early cat specimens, which revealed that cats found in Europe and Turkey from between 11,000 and 2,300 years ago were not the direct ancestors of today's domestic cats. They were instead European wildcats (Felis silvestris) that had naturally hybridized with African wildcats where the ranges of the species overlapped.
"We successfully reconstructed nuclear genomes of several Neolithic cats from Anatolia and Southeast Europe and proved that these cats are European wildcats," said Marco De Martino, a palaeogeneticist at the University of Rome Tor Vergata and lead author of the first study.
"They were likely exploited for food, pelts or ritual practices," he told Live Science. These weren't pets — they were meant for the stew pot or the collar of a luxurious cloak or as offerings to deities.
Instead, the researchers suggest that cat domestication occurred in Africa — either in Egypt or another northern area of the continent, such as modern-day Morocco or Tunisia.
Their analysis indicated that modern domestic cats are most genetically similar to African wildcats from Tunisia.
To piece together the domestic cat's introduction to the world, the authors then looked at non-genetic evidence of cats in societies in ancient times.
Egypt was the most prominent early civilization to encourage the presence of cats, with evidence indicating that they were well-established there by the first millennium B.C., according to the authors.
They were worshipped as part of the cult of Bastet, an Egyptian goddess associated with fertility, health, protection and domestic life. Cats are common in ancient Egyptian imagery, both as members of human households and in the form of Bastet herself — early depictions of the goddess style her as a lion, but she later resembled a domestic cat.
Based on evidence both from iconography and extensive mummification of cats as part of the worship of Bastet, the second paper concludes that Egypt was likely the main center of cat domestication. While the felines may have been drawn to agricultural production by rodents, one variation of the the hypothesis suggests that they were bred for the production of mummies used in devotional rituals. The large-scale breeding operations may have initiated the domestication process.

Cats likely then moved north from Egypt via trade routes. Specimens found in the U.K., date to the late Iron Age, suggesting there was one early wave of cats entering Europe during this period. Domesticated cats then moved into Europe with greater intensity during periods of Greek and Roman dominance.
However, the authors caution that genetic data from mummified cat remains in Egypt has not yet been reliably analyzed. "We believe that Egypt remains the best candidate as the birthplace of domestic cats given the extensive extant iconographic evidence, but we have no genetic data from Egypt to demonstrate that," noted De Martino, who was a co-author on the second paper as well.
On genetic grounds, at least, origins in western North Africa may be on firmer ground.
"The lack of genomic data from ancient or modern cats in Egypt is the big question mark that needs to be answered — when that is added, it may swing genetic support back to the Out of Egypt hypothesis," Losos said.

When did our solar system's planets form? Discovery of tiny meteorite may challenge the timeline

A tiny meteorite is rewriting what scientists thought they knew about the origins of our solar system. New evidence found in shavings from a meteorite known as Northwest Africa 12264 — a 50-gram (1.8 ounces) piece of space rock that is believed to have formed in the outer solar system — suggests that rocky planets like Earth and distant icy bodies may have formed at the same time. This challenges the long-standing belief that planets closer to the sun formed before those in the outer solar system, the ones that lie beyond the asteroid belt between Mars and Jupiter. Planets form within the rotating disks of gas and dust that surround young stars, where particles collide and stick together through a process known as accretion. As developing rocky planets heat up, they begin to differentiate, forming separate internal layers known as the core, mantle and crust. Scientists have thought that our solar system's inner rocky planets — Mercury, Venus, Earth and Mars —formed first (around 4.566 billion years ago), while gas giants and icy bodies in the outer solar system came together slightly later (4.563 billion years ago), due to the colder temperatures at a greater distance from the sun. Rocky planets farther out were also thought to form more slowly because their higher water and ice content would have delayed internal heating and core development. Analyzing the composition of the meteorite (which was purchased from a dealer in Morocco in 2018) revealed a ratio of chromium and oxygen that indicates it came from the outer part of the solar system. Using precise isotopic dating methods, the researchers found that the rock formed 4.564 billion years ago — just two to three million years after the solar system's earliest solid materials. Until now, such early formation was thought to be limited to bodies from the inner solar system, according to a statement announcing the new study.

These 3 popular skywatching star clusters may be branches of the same family tree

Three of the most popular targets for astronomers of all skill levels are the Seven Sisters (the Pleiades), the Hyades and the Orion Nebula Cluster (ONC), which is the central "star" in Orion's Sword. Now, scientists have discovered that these celestial bodies may have more in common than once thought. The star clusters may share a common origin mechanism, they say, despite the fact that the three clusters are all different ages and are located at different distances from Earth. This new research suggests looking at the three star clusters is like looking at three snapshots taken of the same person at three different stages of their life, from infancy to old age. The youngest of these open clusters is the ONC at 2.5 million years old. Located around 1,350 light-years away and packed with thousands of young stars embedded in the stellar cloud that created them, it is one of the most active star-forming regions in the Milky Way. Located 444 light-years from Earth, the Pleiades is less densely packed than the ONC, but it is much more ancient at 100 million years old. However, the Hyades, located 151 light-years away, has fewer stars that are even more thinly spread out and is around 700 million years old. Yet, as diverse as these star clusters seem, the team's new research suggests they share a particular kind of ancestor. "Our highly precise stellar dynamics calculations have now shown that all three star clusters originated from the same predecessor," team member and University of Bonn researcher Pavel Kroupa said in a statement. Star clusters on the same cosmic family tree The team compares the varied ages and conditions in these three star clusters to looking at the same human being through photos that document the stages of their life. The densely packed ONC is the baby, the more dispersed Pleiades is the adolescent, and the Hyades is the elderly person. Though the three clusters didn't form from the same molecular cloud of dense gas and dust, they can be compared to the same person being born three times in different parts of the globe. "From this, we can learn that open star clusters seem to have a preferred mode of star formation," Kroupa explained. "It appears that there is a preferred physical environment in which stars form when they evolve within these clouds." The question is: How does a cluster like the ONC develop into one like Pleiades and then age into a cluster like the Hyades? Kroupa and colleagues, including team leader Ghasem Safaei from the Institute for Advanced Studies in Basic Sciences, set about answering this question with computer simulations. Star clusters grow old gracefully The team's simulations revealed the forces acting between stars in a cluster. This allowed the scientists to model the life cycle of such a collection of stars from a gas-rich, dense infancy through gradual expansion and gradual gas and star loss over the course of 800 million years. The results obtained by the team closely reflected the changes in structure and composition between the phases we see exemplified by the ONC, the Pleiades and the Hyades. "This research shows that it is entirely plausible that star clusters such as the ONC follow a development path that transforms them into systems like Pleiades and later on Hyades," Hosein Haghi, study team member and a researcher at the University of Bonn, said in the statement. The team's results indicated that clusters like the ONC can lose up to 85% of their stellar population and yet hang on to coherent structures when they reach ages similar to that of the Hyades while passing through a stage that resembles the Pleiades. The team's research also suggests that the fact these three clusters appear close together in the night sky over Earth, despite being widely separated in the cosmos, may be more than a mere coincidence. This positioning could, in fact, be related to the way star clusters form and evolve in relation to our galaxy. "This research gives us a deeper understanding of how star clusters form and develop and illustrates the delicate balance between internal dynamics and external forces such as the gravitational pull of the Milky Way," team member Akram Hasani Zonoozi of the University of Bonn said in the statement.

Astronomers crack 1,000-year-old Betelgeuse mystery with 1st-ever sighting of secret companion (photo, video)

When you buy through links on our articles, Future and its syndication partners may earn a commission. After a long wait, astronomers have finally seen the stellar companion of the famous star Betelgeuse. This companion star orbits Betelgeuse in an incredibly tight orbit, which could explain one of Betelgeuse's longstanding mysteries. The star is doomed, however, and the team behind this discovery predicts that Betelgeuse will cannibalize it in a few thousand years. The fact that Betelgeuse is one of the brightest stars in the sky over Earth, visible with the naked eye, has made it one of the most well-known celestial bodies. And ever since the first astronomers began inspecting this fixture in the night sky, they have been baffled by the fact that its brightness varies over periods of six years. This mystery is now solved. The six-year dimming of this red supergiant star is not to be confused with an event that saw it drop sharply in brightness over 2019 and 2020. This event, known as the "Great Dimming," sparked intense interest across the globe. The Great Dimming was so unexpected that it led some scientists to theorize that it could signal Betelgeuse was approaching the supernova explosion that will one day mark the end of its life. That supernova speculation was well-founded. After all, though it is only around 10 million years old, the fact that Betelgeuse is 700 times the size of the sun means it has burned through its nuclear fuel much faster than our 4.6 billion-year-old star. That means its supernova death is likely approaching. However, in 2023, the Great Dimming was explained by a giant obscuring cloud of dust emitted by Betelgeuse. Even though the mystery of the Great Dimming was solved, this event spurred a renewed interest in this ever-so familiar star, the tenth brightest in the night sky. That renewed interest included the desire of astronomers to solve the less dramatic but more regular periodic dimming of Betelgeuse. The lesser dimming of Betelgeuse Betelgeuse has a primary period of variability that lasts around 400 days, as well as a second, more extended dimming period lasting around six years. Unlike the Great Dimming, which perplexed scientists for only a few years, this regular "heartbeat" of Betelgeuse has baffled humanity for millennia! It was while reviewing archival data that scientists began to theorize that the six-year variability of Betelgeuse could be the work of a hidden companion star. However, deeper investigation with the Hubble Space Telescope and NASA's X-ray space observatory Chandra left scientists coming up empty-handed in terms of a companion star. Undeterred, NASA Ames Research Center scientist Steve Howell led a team of astrophysicists who set about investigating Betelgeuse with the Gemini North telescope and its 'Alopeke (Hawaiian for "fox") instrument. "Gemini North's ability to obtain high angular resolutions and sharp contrasts allowed the companion of Betelgeuse to be directly detected," Howell said in a statement. "Papers that predicted Betelgeuse's companion believed that no one would likely ever be able to image it." The 'Alopeke instrument uses a technique in astronomy called "speckle imaging" that uses short exposure times to remove distortions from images that are caused by Earth's atmosphere. This provided the Gemini North telescope with the high-resolution capability to detect the faint companion of Betelgeuse for the first time ever. Howell and colleagues were able to do more than just image the companion star of Betelgeuse; they were also able to determine some of its characteristics. What do we know about Betelgeuse's companion? The team thinks the star has a mass around 1.5 times that of the sun and that it is a hot blue-white star orbiting Betelgeuse at a distance equivalent to four times the distance between Earth and the sun, fairly close for binary stars. That means it exists within the extended atmosphere of Betelgeuse. This represents the first time a companion star has been detected so close to a red supergiant. The team also theorizes that this star has not yet begun to burn hydrogen in its core, the process that defines the main sequence lifetime of a star. Thus, the Betelgeuse system appears to consist of two stars that exist at opposite ends of their lives, despite the fact that both stars formed at the same time! That's because larger and more massive stars don't just burn through their nuclear fuel more rapidly; they also initiate the fusion of hydrogen to helium earlier. However, in this case, this delay doesn't mean that Betelgeuse's companion is in for a long life; the intense gravity of Betelgeuse is likely to drag the smaller star into it, devouring it. The team estimates this cannibalistic event could happen within the next 10,000 years. In the meantime, astronomers will get another look at the stellar companion of Betelgeuse in November 2027 when it achieves maximum separation from the infamous red supergiant star.

"This detection was at the very extremes of what can be accomplished with Gemini in terms of high-angular resolution imaging, and it worked," Howell said. "This now opens the door for other observational pursuits of a similar nature." The team's research was published on Monday (July 21) across two papers in The Astrophysical Journal.
