Sunken body found by divers offers clues to American origins
The ancient remains of a teenage girl discovered deep underground in Mexico are providing additional insights on how the Americas came to be populated.
Divers found the juvenile’s bones by chance in a vast, flooded limestone chamber on the Yucatan Peninsula.
Aged 15 or 16 at death, the girl lived at least 12,000 years ago.
Researchers have told Science Magazine her DNA backs the idea that the first Americans and modern Native American Indians share a common ancestry.
This theory argues that people from Siberia settled on the land bridge dubbed Beringia that linked Asia and the Americas some 20,000 years ago before sea levels rose.
These people then moved south to populate the American continents.
The genetics of modern Native Americans would certainly appear to link them into this story. But their facial features set them apart from the oldest skeletons now being unearthed.
These ancient people had narrower, longer skulls. The differences have hinted that perhaps there were multiple immigrations from Siberia (or even Europe).
However, the remains of the Yucatan girl, dubbed Naia – which means “water nymph” in Greek – does not follow that line of thinking, because although she had the slender features associated with the earliest Americans, her DNA shares commonalities with modern Native Americans.
Lab analysis of teeth and bone samples link her to a particular genetic lineage known as Haplogroup D1.
This same marker is found in substantial numbers of modern Native Americans.
“This lineage is thought to have developed in Beringia, the land that now lies beneath the Bering Sea after its ice age occupants became genetically isolated from the rest of Asia,” explained lead author Dr Jim Chatters.
“Thus, Naia, one of the earliest occupants of the Americas yet found, suggests that Paleoamericans do not represent an early migration from a part of the world different than that of the Native Americans.
“Rather, Paleoamericans and Native Americans descended from the same homeland in Beringia.
“The differences between them likely arose from evolution that occurred after the Beringian gene pool became separated from the rest of the world.”

Palau Resurfaces! Visit Us at boot 2025 in Duesseldorf and Discover Why!
Following a period away, Palau – a dream destination for countless divers – is excited to rejoin the boot water sports show in Duesseldorf, Germany.
This prestigious water sports show, taking place from January 18 to 26, 2025, provides Palau with a platform to showcase its unique offerings in diving, snorkelling, and sustainable tourism.
Located in the western Pacific’s Micronesian region and part of the Caroline Islands, the Republic of Palau comprises over 340 picturesque islands. Although small in landmass, Palau is a natural wonder both above and below the water.
Palau is renowned as a global leader in environmental conservation. Years ago, the nation implemented forward-thinking measures to preserve its natural resources. In 2009, Palau became the world’s first national shark sanctuary, banning commercial shark fishing. To further protect its marine ecosystem, home to over 1,500 fish species and about 700 coral species, Palau established a fully protected marine sanctuary spanning 193,000 square miles in 2015.
Palau’s return to the boot shows marks a significant moment for the island nation, celebrated for its crystal-clear waters, pristine coral reefs, and extraordinary marine biodiversity. Visitors to the Palau booth will discover a vision of sustainable tourism, as environmental stewardship is deeply ingrained in the islanders’ way of life.
“We are thrilled to return to Germany and share the beauty and diversity of Palau with the world,” says Kadoi Ruluked, Managing Director of the Palau Visitors Authority, who will lead the delegation at the trade show. “boot provides an outstanding platform to position Palau as a premier destination for sustainable tourism and a true paradise for underwater adventures.”
Amid growing global efforts toward eco-friendly tourism, Palau continues to set benchmarks with initiatives such as the “Palau Pledge.” By signing this pledge, visitors commit to respecting and protecting the environment during their stay. These and other measures will be highlighted at the event to raise awareness of marine ecosystem conservation.
The boot water sports show offers a unique opportunity for visitors to immerse themselves in Palau’s culture and natural beauty while planning unforgettable diving and snorkelling trips. The Palau Visitors Authority warmly invites all attendees to explore their booth and experience the unspoiled charm of Palau.
Learn everything there is to know about this extraordinary destination at
Hall 12, booth nr. E42.
The exhibition runs from January 18 to 26, 2025, in Duesseldorf.

Gear Review: SurfEars 4
Let me get this out there at the start… it is not possible for me to write an unbiased review on SurfEars! Why? – because they saved my diving career. That may sound over-dramatic, but it is true. I had been told by my ENT specialist that I should stop diving. Repeated perforations, including a stint of 4 infections causing ear drum ruptures in a single year, meant that things looked very bleak. Until a friend recommended that I get in touch with the team at SurfEars and to try them out.
That was over 5 years ago, and I have not looked back. Not a single ear infection in all the dives since. If you want to read my initial review of SurfEars then you can find it here: https://www.scubaverse.com/gear-review-surfears/
So, I was more than pleased to receive the latest SurfEars 4 to try out. I took them on a recent trip to The Bahamas where I was filming for a new project all about sharks. SurfEars come in a handy pod that I secure to my BCD so that I am sure not to forget to take them on the boat and to put them in before I head into the water. The new model comes in 2 new colours and have a range of fittings to ensure a perfect fit. Once in, you can still hear what is going on around you. Vital for any last-minute instructions for your dive.
Underwater they do their job in keeping water out. It is still just as easy to equalise the pressure, as air movement is not restricted at all. The new fittings mean that I can change to a slightly smaller fitting to wear under my hood for cold water diving. Once in, I just forget all about them, and enjoy my diving (snorkeling and swimming) with complete peace of mind.
The new version of SurfEars is now using recycled ocean plastic and repurposed silicone so are more eco-friendly. They are said to be even tougher and will last longer. Although my previous set were still going strong.
Whatever your chosen water sport – I cannot recommend SurfEars enough. Whilst they literally enabled me to continue diving, I would suggest using them to protect your ears before any unwanted trips to the doctor. I never go in the water without them. They are at the top of my packing list for any trip.
