Woolly mammoth extinction blamed on climate change, not human hunting

«This is a stark lesson from history and shows how unpredictable climate change is — once something is lost, there is no going back.»

About 4,000 years ago, the last majestic woolly mammoth roaming Earth vanished, and for decades, scientists believed the colossal ancestors of elephants went extinct because humans hunted them relentlessly. DNA analysis of the animals’ old stomping grounds, however, reveals a different story.

The likelier culprit, researchers now say, was rapid climate change that ultimately wiped out the creatures’ food supply. But besides solving the mystery of the disappearing mammoths, these findings may offer a glimpse into the fates of other species if our present climate crisis isn’t controlled.

«We have shown that climate change, specifically precipitation, directly drives the change in the vegetation — humans had no impact on [the mammoths] at all based on our models,» Yucheng Wang, a zoologist at the University of Cambridge and first author of the paper published Wednesday in the journal Nature, said in a statement.

Co-author Eske Willerslev, a fellow at the University of Cambridge and director of the Lundbeck Foundation GeoGenetics Centre at the University of Copenhagen, added, «This is a stark lesson from history and shows how unpredictable climate change is — once something is lost, there is no going back.»

These gentle beings that dined on grass and flowers lived alongside Neanderthals. While many encounters might have been peaceful, the animals were a hot commodity when it came to making fur coats, musical and artistic instruments and hearty meals. That’s because of their thick, chocolate-colored fur, their sturdy, enormous tusks and their huge size.

They weighed approximately 6 tons and stood about 13 feet (4 meters) tall — as Wang puts it, woolly mammoths could «grow to the height of a double-decker bus.»

«Scientists have argued for 100 years about why mammoths went extinct,» Willerslev said. «Humans have been blamed because the animals had survived for millions of years without climate change killing them off before, but when they lived alongside humans they didn’t last long and we were accused of hunting them to death.»

It makes sense that prehistoric people were suspected to be behind woolly mammoths’ eventual demise instead of climate change. These animals somehow withstood the Ice Age about 12,000 years ago — the fanciful Disney movie Ice Age has some thoughts on that — but the new study’s researchers decided to dig a little deeper.

Over a period of 10 years, Willerslev led a team in dissecting DNA fragments collected from the Arctic soil where mammoths were known to graze. The samples were collected over 20 years and analyzed using a method called DNA shotgun sequencing.

DNA shotgun sequencing is an indirect way to create genetic profiles without requiring a person or animal to physically be there. Instead of collecting genetic information from bones or teeth, the method sequences DNA from traces of urine or discarded cells. Scientists have also used this tool to track the movement of COVID-19 by creating DNA profiles from sewage remnants.

The researchers looking into ancient mammoths discovered populations of the enormous animals — uncovered using the sequencing method — were depleted at a rate consistent with the quick speed of climate change at the time. Willerslev says it was because «as the climate warmed up, trees and wetland plants took over and replaced the mammoth’s grassland habitats.»

«When the climate got wetter and the ice began to melt, it led to the formation of lakes, rivers and marshes,» he said. «The ecosystem changed and the biomass of the vegetation reduced and would not have been able to sustain the herds of mammoths.»

Wang also notes that prehistoric humans would’ve probably spent most of their time hunting animals much smaller and easier to capture than enormous woolly mammoths, suggesting their impact on the animals’ extinction was arguably smaller than intuitively thought.

Another important aspect of the findings, Wang said, is «we have finally been able to prove that it was not just the climate changing that was the problem, but the speed of it that was the final nail in the coffin — they were not able to adapt quickly enough when the landscape dramatically transformed and their food became scarce.»

Such speed is why the researchers naturally drew parallels between what happened back then and what appears to be in store for us now. For instance, our global temperature is rising so quickly that many countries’ former goal of limiting the increase to 1.5 degrees Celsius (2.7 degrees Fahrenheit) is now considered nearly impossible by the UN’s Intergovernmental Panel on Climate Change. That’s unless immediate, drastic measures are taken, they say.

«It shows nothing is guaranteed when it comes to the impact of dramatic changes in the weather,» Willerslav said. «The early humans would have seen the world change beyond all recognition. That could easily happen again, and we cannot take for granted that we will even be around to witness it.»

«The only thing we can predict with any certainty is that the change will be massive.»

Made by Google 2025: Everything Announced — Pixel 10, Pixel Watch 4, Pixel 10 Pro Fold

At a star-studded event hosted by late-night host Jimmy Fallon, Google announced new phones, watches, earbuds and Android features.

Even though the Pixel 10 leaks and rumors felt as if they arrived in a steady firehose before today’s Made by Google event — compelling the company to release a teaser video pre-announcing the new phone’s existence a month ago — Google still delivered details it somehow managed to keep private until it was ready to share.

And that delivery was refreshingly fun for a tech event. The Tonight Show host Jimmy Kimmel led the proceedings in a very late-night talk show format, bringing on several special guests from media, sports and yes, Google’s own experts to show off the products and features they’ve been working on for today’s announcements.

Pixel 10, Pixel 10 Pro and Pixel 10 Pro XL are real

Surprise, Google announced new phones! OK, this was the least surprising part of the event, but it still feels good to finally know what exists and when it’s coming. Preorders for the Pixel 10, Pixel 10 Pro and Pixel 10 Pro XL begin today and will be in stores and shipping starting August 28.

Pixel 10 Pro Fold opens the next chapter of foldables

Folding phones so far have shared an Achilles Hinge: small particulates like sand can get inside the case and really mess things up. The Pixel 10 Pro Fold is one of the first to have an IP68 rating for dust and water resistance, meaning you can take it to the beach.

Pixel Buds Pro 2 owners will see new features

Coming in a software update next month, Pixel Buds Pro 2 owners will be able to answer calls or send them to voicemail with a nod or shake of the head. You’ll be able to talk to Gemini live in noisy locations, and benefit from adaptive audio that applies noise cancellation while letting important sounds come through. At the other end, a new feature will protect your hearing from very loud sounds.

Magic Cue is a Gemini assistant that pulls data from your correspondence

In the rollout of all the various AI technologies in the industry, the current stretch goal is «agentic» interactions with software: Having an AI that knows all sorts of details about you and can act to get the important stuff in front of you when needed. (And do it in a privacy-first way, one would hope.)

Magic Cue is Google’s implementation. It’s a new Gemini-based feature that can look through your earlier messages, emails and photos to pull details about things like restaurant reservations and flight times. Magic Cue runs on the Pixel device itself, so sensitive data stays private and not shared to the cloud.

A lot of Gemini AI intelligence is still coming soon

At the start of the event, Kimmell sat down in typical talk-show format with Rick Osterloh, senior vice president of platforms and devices, to chat about Gemini and the marvels of AI. Aside from Magic Cue, which will be shipping on the Pixel 10 phones, a lot of the features we’ve been hearing about are still on the horizon.

«For instance, Gemini could do something like plan a team celebration dinner for 12 people tonight,» he said. «It might go find a restaurant that’ll accommodate that group…. Look for a karoake place nearby and maybe even order custom T-shirts for the celebration.»

And when will that be possible? Kimmell asked. «A lot sooner than people think,» Osterloh replied. «This kind of thing is coming this year.»

The Pixel 10 Pro and 10 Pro XL can zoom to 100x with AI help

Pro Res Zoom on the Pixel 10 Pro phones pushes zooming far beyond what would seem to be possible with typical small cameras. Usually when you zoom beyond the optical limits of the cameras, details get fuzzy as the software upscales the image. With Pro Res Zoom, when you go beyond 30x zoom, it uses generative AI to build a sharper version. CNET’s Andrew Lanxon got both impressive and head-scratching results while making photos in Paris using the Pixel 10 Pro XL.

Camera Coach uses AI to encourage better photos

Smartphone cameras have employed AI for several years, such as identifying subjects in order to blur the background for Portrait modes or quickly snapping several shots at multiple exposures and blending them together to create well-balanced lighting throughout. Now Google is using AI to help you take better photos.

Camera Coach is a new feature in the Pixel Camera app that looks at the scene in front of the lens and generates multiple suggestions for how to improve the photo before it’s captured. To show this off, podcaster Alex Cooper brought Fallon out to be her model and sat him down on a couch. When she activated the feature, Camera Coach suggested that she move the camera closer to the subject, position his head in the upper portion of the frame, lower the camera to eye level and turn on Portrait mode.

«To all the girls that are watching, I personally know how hard it is to train your boyfriend or your husband to get that perfect shot,» said Cooper. «And now Camera Coach can just train all the boys for us.»

Pixel 10 supports Qi2 magnetic charging

The Qi2 spec includes not just faster charging but also an array of magnets on the back for connecting to accessories. Sound familiar? The presenters mentioned Apple’s MagSafe system, then paused with the realization that they probably shouldn’t have name-checked it during the Google event. On the Pixel 10 phones, it’s called Pixelsnap and should work with accessories made for Apple’s ecosystem too.

Pixel 10 will be available in Mexico

In an impressive segment demonstrating Gemini live translation during a phone call, musician Karen Polinesia, who speaks Spanish, announced that for the first time, the Pixel 10 will be available for sale in Mexico.

Upgrading to Pixel 10? Here’s How to Prepare Your Old Pixel for Trade-In

Don’t send off your phone with a ton of personal information still on it.

Google just announced the Pixel 10 family, and several preorder offers are available right now. If you’re looking for an even better deal on these new phones, you might want to consider trading in your old Pixel for maximum savings.

The Pixel 10 family consists of the base Pixel 10 model, two Pro models and the latest Pro Fold. All of these phones feature the latest Tensor G5 Processor, Qi2 wireless charging and, of course, new AI tricks. We went hands-on with the new phones, and they made a good impression.

If you’re ready to leap into a new Pixel, you’ll want to make sure you’ve prepared your old phone properly before you send it off.

If you don’t check all the right boxes for trading in your phone, its trade-in value could be reduced. You also want to avoid sending your phone out with a ton of personal information still left on it.

Below, we’ll go over the steps to ensure a seamless trade-in experience when your new Pixel 10 arrives.

For more, we’ve wrangled all of the best Pixel 10 cases you can buy right now.

Turn off the activation lock on your Pixel phone

Before you trade in your phone, you’ll just need a factory reset to qualify for the maximum trade-in value. Some retailers want you to remove the activation lock from your phone first, which requires removing the device from your Google account before resetting it. (AT&T took off over $400 of the value because I didn’t do this to my Pixel 7 Pro when I upgraded to the 8 Pro a few years back.)

You can remove your Google account from your phone directly or via your online account.
