DNA Tests Show ‘Extinct’ Penguin Species Never Existed

Science is a self-correcting process, ever in flux. Accepted hypotheses are overturned in the face of new information. The world isn’t flat after all. Disease isn’t caused by demons or wickedness. And that Hunter Island penguin? Yeah, apparently that was just a figment of our imaginations. Researchers writing in the Zoological Journal of the Linnean Society say the remains of one supposed species are in fact a “jumbled mixture” of bones from three extant species.

The bones were unearthed in the 1980s during the excavation of a prehistoric trash heap on Tasmania’s Hunter Island. Two scientists named Tets and O’Connor argued that the remains were different enough from other penguins to constitute their own genus and species, one which must have died out during the Holocene epoch. The proud potential penguin parents dubbed the apparently extinct bird Tasidyptes hunterivan, and that was that.

Except that this is science, where no story is ever really over. Other biologists were not satisfied with the evidence Tets and O’Connor presented. There were only four bones, and they all bore some resemblance to species that exist today. Fortunately, in 2017, we’ve got ways of making fossils talk. A research team led by Tess Cole of the University of Otago used DNA barcoding to examine the genetic code of each of the four bones.

“It was a fun and unexpected story,” Cole said in a statement, “because we show that Tasmania’s ‘extinct' penguin is not actually an extinct or unique penguin at all.”

The bones were “a jumbled mixture of three living penguin species, from two genera": the Fiordland crested penguin or Tawaki (Eudyptes pachyrhynchus) and the Snares crested penguin (Eudyptes robustus), both of New Zealand, and the Australian little fairy penguin (Eudyptula novaehollandiae).

“This study shows how useful ancient DNA testing can be,” Cole said. “Not only does it help us identify new but extinct species, but it can help us rule out previously postulated species which did not exist, as in this case.”

The Cat Art Show Is Coming Back to Los Angeles in June

After dazzling cat and art lovers alike in 2014 and again in 2016, the Cat Art Show is ready to land in Los Angeles for a third time. The June exhibition, dubbed Cat Art Show 3: The Sequel Returns Again, will feature feline-centric works from such artists as Mark Ryden, Ellen von Unwerth, and Marion Peck.

Like past shows, this one will explore cats through a variety of themes and media. “The enigmatic feline has been a source of artistic inspiration for thousands of years,” the show's creator and curator Susan Michals said in a press release. “One moment they can be a best friend, the next, an antagonist. They are the perfect subject matter, and works of art, all by themselves.”

While some artists have chosen straightforward interpretations of the starring subject, others are using cats as a springboard into topics like gender, politics, and social media. The sculpture, paintings, and photographs on display will be available to purchase, with prices ranging from $300 to $150,000.

Over 9000 visitors are expected to stop into the Think Tank Gallery in Los Angeles during the show's run from June 14 to June 24. Tickets to the show normally cost $5, with a portion of the proceeds benefiting a cat charity, and admission will be free for everyone on Wednesday, June 20. Check out a few of the works below.

How a Pregnant Rhino Named Victoria Could Save an Entire Subspecies

The last male northern white rhino died at a conservancy in Kenya earlier this year, prompting fears that the subspecies was finally done for after decades of heavy poaching. Scientists say there's still hope, though, and they're banking on a pregnant rhino named Victoria at the San Diego Zoo, according to the Associated Press.

Victoria is actually a southern white rhino, but the two subspecies are related. Only two northern white rhinos survive, but neither of the females in Kenya are able to reproduce. Victoria was successfully impregnated through artificial insemination, and if she successfully carries her calf to term in 16 to 18 months, scientists say she might be able to serve as a surrogate mother and propagate the northern white rhino species.

But how would that work if no male northern rhinos survive? As the AP explains, scientists are working to recreate northern white rhino embryos using genetic technology. The San Diego Zoo Institute for Conservation Research has the frozen cell lines of 12 different northern white rhinos, which can be transformed into stem cells—and ultimately, sperm and eggs. The sperm of the last northern white male rhino, Sudan, was also saved before he died.

Scientists have been monitoring six female southern white rhinos at the San Diego Zoo to see if any emerge as likely candidates for surrogacy. However, it's not easy to artificially inseminate a rhino, and there have been few successful births in the past. There's still a fighting chance, though, and scientists ultimately hope they'll be able to build up a herd of five to 15 northern white rhinos over the next few decades.
