Physical Editions of Grand Theft Auto 6 won't come with a discMany fans are disappointed, and it's stirred conversation about the value of physical and digital gamesFans in 2013 had similar conversations with the launch of GTA 5Now that Grand Theft Auto 6 pre-orders are live, it feels like the countdown to the game's launch later this year can truly begin in earnest. And yet, despite the hype around the most anticipated game of all time, some fans are disappointed by the announcement that physical editions won't come with a disc, but rather a digital download code in the box. It has stirred up conversation around whether physically owning the game even matters in the grand scheme of things; dedicated fans who have waited a long time for GTA 6 will buy the game either way, right?"Obviously I’m going to get this game but 13 years of waiting & this is all physical editions are getting? A f****** code in a box? For the biggest game to ever launch & that’s all the effort you’re putting in for physical? So damn disappointed man," one said.But it seems that even during the launch period of GTA 5 all the way in 2013, fans were debating the value of physical and digital games, though it seems that many leaned on the side of being able to physically own their copy."I have been playing the game since launch, because my brother bought it and never played it. He recently moved and took the game with him, so I need to buy it myself. I have an external hard drive which I can store the game on so I don't have to worry if the Xbox breaks. Now what would you recommend?" asked a fan on a 12-year-old Reddit post.One fan jumped to say that "Physical is seemingly better in every way aside from you have to remove the disk [from the console]."Others agreed, with one saying, "Plus, if you ever want to get rid of it, you can always trade it in for another game or sell it."However, it's a different conversation today as GTA 6 physical editions will have a download code instead, unlike GTA 5 over a decade ago, meaning players won't be able to resell their copy later on. @techradar ♬ original sound - TechRadar One fan disagreed, saying, "Wow. Really everyone is still on physical what is this the 20th century?" But another argued that physical is better because they could display their collection proudly."Physical, as the price is usually the same as digital," a user replied, but nowadays, that's not typically the case, while another said "Physical, cause you get the map. Not cause its useful just cause its cool!"Sadly, unlike GTA 5 and even Red Dead Redemption 2, neither the Standard nor the Ultimate Edition of GTA 6 will include a map. Before GTA 5 was released, hours of gameplay footage leaked online after early copies were illegally uploaded to torrent sites. One explanation for GTA 6 physical editions not including a disc could be that Rockstar is trying to minimize the potential for leaks this time around.Some fans also considering skipping the day one purchase in hopes of a disc being produced later down the line. However, for now, it looks like all players will own a digital license for the game instead.GTA 6 launches on November 19 and will cost $79.99 / AU$129.95 / £69.99 for the Standard Edition and $99.99 / AU$159.95 / £89.99 for the Ultimate Edition. Pre-loads begin on November 12.

Nearly 70,000 years ago, modern humans created stunning rock art in an unexpected place: the tropical Indonesian island of Sulawesi. The finding, announced in January, made headlines for being the oldest known rock art in the world. But the discovery's location also highlighted another surprising finding: that members of our species, Homo sapiens, were thriving in the tropics tens of thousands of years ago. Researchers have long thought that early humans didn't live in tropical rainforests, as these places haven't yielded human fossils and are teeming with dangerous life, including venomous animals, poisonous plants and parasites that would deter early populations. But that perspective has been changing over the past few decades. Sulawesi's ancient rock art is one of several clues that modern humans may have lived in tropical rainforests for hundreds of thousands of years. That would mean modern humans could have been living in these hot, wet regions since soon after the emergence of our species in Africa around 300,000 years ago. Understanding how, when and where modern humans inhabited rainforests — and how that shaped our evolution — "may give us an insight into something about what it means to be uniquely human," Patrick Roberts, an archaeologist and anthropologist at the Max Planck Institute of Geoanthropology and author of the book "Jungle: How Tropical Forests Shaped World History" (Penguin, 2022), told Live Science. From one origin story to manyConventional wisdom held that modern humans emerged from one parent population in an East African savanna and did not encounter rainforests until around 12,000 years ago, after agriculture emerged to support survival in these climes. The lack of H. sapiens fossils from Africa's tropics appeared to support this view. Then, in 2017, scientists identified the oldest modern-human fossils — except they weren't in East Africa, but rather in Jebel Irhoud, Morocco. The following year, Eleanor Scerri, an archaeological scientist at the Max Planck Institute of Geoanthropology in Germany, and her colleagues reviewed archaeological evidence, including the Jebel Irhoud fossils, and integrated it with genetic data from present-day populations. The evidence pointed toward H. sapiens originating from many subdivided populations across Africa. These populations periodically met and exchanged genes and ideas, but they also spent long periods apart, adapting to different ecosystems and evolving diverse traits. In this new understanding, the earliest members of our species may have evolved not just in the grassy savanna but in tropical rainforests, too. "One of the implications of the model is, if it's not one place and it's many places, then maybe it's not one ecosystem," Scerri told Live Science. "Maybe it's many ecosystems."Tropical rainforests were long considered too challenging for early members of our species to have lived in. (Image credit: Richard McManus via Getty Images)Because rainforests come with their own set of environmental pressures, people who lived there may have evolved traits to handle those challenges. When different early human populations came together, tropical rainforest dwellers would have contributed different gene variants than populations from open savannas. The ability to adapt to a variety of environments, including rainforests, may have come in handy later, when H. sapiens spread out of Africa and into tropical Southeast Asia, including places like Sulawesi. But establishing what these traits were would first require evidence that humans lived in rainforests close to the dawn of our species. Rainforests are terrible for fossil huntersUnfortunately, the highly acidic soil in rainforests degrades organic material like bones. This makes evidence of ancient humans, such as fossils, or human activities, like bone arrows or potential woven fiber baskets, exceptionally rare in rainforests. Even in the few instances this evidence is found, the conditions make it hard to date and contextualize it. Archaeologists often date early human fossils by measuring radioactive isotopes (versions of elements), such as carbon-14, in distinct, undisturbed layers of sediments — broken-down rocks and minerals that form via erosion and weathering. The more sediment layers there are, the longer the period of history that can be traced. But weather conditions in West and Central Africa's rainforests have left few long sediment sequences. The lack of long sediment sequences also significantly reduces the odds of finding fossils at all, said Antonio Rosas, a paleobiologist at the National Museum of Natural Sciences in Spain who has been searching unsuccessfully for such fossils in Equatorial Guinean rainforests since 2014. "To be honest, I think I gave up the possibility of finding fossils properly," Rosas said. Written in stoneAs a result, many researchers studying early H. sapiens evolution have focused on a material that does preserve: stone. In Africa, stone tools reveal humans were in coastal tropical forests in what is now Kenya roughly 78,000 years ago, the tropical rainforests of what is now Equatorial Guinea from around 45,000 years ago, and the rainforests of what is now the Democratic Republic of the Congo around 18,000 years ago. Then, in 2025, researchers revealed that stone tools previously found in a tropical rainforest in the Ivory Coast in the 1980s were 150,000 years old. Because the area was also a tropical rainforest 150,000 years ago, this is evidence that our species inhabited rainforests "much earlier than previously thought," study first author Eslem Ben Arous, a geochronologist and archaeologist at the National Research Center on Human Evolution in Spain, told Live Science in an email. Stone tools like this one, excavated in the Ivory Coast, reveal that humans were present at the rainforest site roughly 150,000 years ago. (Image credit: Jimbob Blinkhorn, MPG)The antiquity of these quartz tools — which were a mix of flakes and heavy-duty picks and choppers — show that early H. sapiens were capable of designing technology to survive in dense tropical forests. Dense forests weren't a barrier for early humans at that time, Ben Arous said. Direct evidenceAlthough stone tools show ancient people were venturing into forests for food or living there part time, they don't prove humans lived there year-round. To do that, researchers still need fossils.By analyzing the isotopes of elements found in human tooth enamel, researchers can reveal whether our distant relatives actually lived in rainforests. That's because closed, dense canopy rainforests have low levels of sunlight and high carbon dioxide, and the ratio of isotopes of elements in a person's teeth can reveal if they spent a lot of time in those conditions as a child. Currently, zinc isotopes in two 46,000- to 63,000-year-old human teeth found in Tam Pà Ling cave in Laos are the oldest evidence of humans eating foods mainly from a tropical rainforest. Similar evidence is currently lacking from African rainforests. But the ability to adapt to many different environments, including rainforests, and the capacity to develop highly specialized traits for such environments is "what's unique about our species," Roberts said. Identifying adaptationsEarly members of our species would have required certain adaptations to live in rainforests. So what were they? Without preserved DNA or fossils, anthropologists guess by looking at contemporary populations living in the tropics. Many modern-day rainforest inhabitants are small, because it may help them cool off more easily, reduce their caloric needs, and make it easier to move in dense rainforests. An analysis published in 2019 also found key differences in genes related to immunity and development in African rainforest hunter-gatherers compared with neighboring farmers. For example, the gene PITX1 — which codes for proteins crucial for limb development — is one of several genes that contributes to small stature and shows strong signs of positive selection in Gabonese hunger-gatherer populations.There is evidence in multiple rainforest dwelling populations, including in those Gabon hunter-gatherers, of selection against specific pathogens. Although early H. sapiens living in rainforests likely faced similar pressures, we don't have any evidence that similar adaptations evolved in these ancient members of our species. Ancient DNA may be the keyBut some scientists hope to someday find evidence of these adaptations in ancient DNA. DNA preservation was historically considered impossible in hot and humid environments, but that assumption "turns out to be only partially true," Miklós Bálint, a functional environmental genomicist at the Senckenberg Biodiversity and Climate Research Centre in Germany, said in a statement. Researchers can find ancient DNA lurking in the environment by analyzing sediment cores from tropical lakes. (Image credit: Annett Junginger)Bálint and his colleagues recently reviewed ancient environmental DNA (aeDNA) recovered from tropical environments. They found 113 studies reported aeDNA in tropical and subtropical habitats between 1998 and 2025, including 1 million-year-old aeDNA extracted from a lake in Indonesia. This DNA came mainly from nearby plants, not from ancient humans. But because people leave "millions of DNA traces" in their environment during their lifetime, human DNA should also be present and retrievable, Bálint said in the statement. "Obtaining DNA data will be a truly fundamental breakthrough in tropical forest research," Ben Arous said. For example, these genetic remnants peppered throughout the environment could reveal how humans changed the ecosystem, how they moved and interbred, and which diseases and parasites ancient people faced.

Current efforts in Benin appear "really, really promising," Scerri said, and she and her team are also working on projects in Guinea, Ghana and Senegal, which are also yielding clues to ancient human habitation. "We're making some incredible finds," she said."There is enough evidence now to justify investigating areas that used to be well off the human origins map, considered to be very far from the main stage of human evolution," Scerri said. The question now is how much further back in time people were living in rainforests and using their resources. "We consider ourselves to really be scratching the surface," Scerri said.
