Scientists reported on Wednesday that they have recovered DNA from the oldest viruses known to have infected humans — and have succeeded in resurrecting some of them in the laboratory.

The viruses were all strains of hepatitis B. Two teams of researchers independently discovered its DNA in 15 ancient skeletons, the oldest a farmer who lived 7,000 years ago in what is now Germany.

Until now, the oldest viral DNA ever recovered from human remains was just 450 years old.

Book Giveaway: Two Is Better Than One!

Earlier this week, I walked into the office of my editor, Stephen Morrow, to discover a stack of books. Real books–not pdf files, not galleys, but hardback copies of She Has Her Mother’s Laugh suitable for curling up in bed with or propping open your front door or cracking open walnuts (warning: past performance is no guarantee of future results).

In celebration of this glorious event, my publisher is going to pick ten Friday’s Elk readers to win a two-book pack: a finished copy of She Has Her Mother’s Laugh, plus The Descent of Man: The Concise Edition. Continue reading “Friday’s Elk, May 4, 2018”

The animal kingdom is one of life’s great success stories — a collection of millions of species that swim, burrow, run and fly across the planet. All that diversity, from ladybugs to killer whales, evolved from a common ancestor that likely lived over 650 million years ago.

No one has found a fossil of the ur-animal, so we can’t say for sure what it looked like. But two scientists in Britain have done the next best thing. They’ve reconstructed its genome.

Their study, published in Nature Communications, offers an important clue to how the animal kingdom arose: with an evolutionary burst of new genes.

One Month To Go!

The official publication date for She Has Her Mother’s Laugh is May 29. My fingernails are already nubs. As any author will tell you, these days pre-orders make a huge difference to the launch of a book. I’m deeply proud of this book and hope you’ll find the subject as fascinating as I did writing about it. Please consider pre-ordering a copy. And tell all your friends who have ever wondered about heredity to consider doing so, too. Ordering early will help me bring the book to the attention of even more potential readers. Many thanks!
 


Big Stories in Little Things

I’ve written another Facebook post about science books. Today, it’s Jonathan Weiner’s The Beak of the Finch, one of the books that showed me as a young science writer how it’s done. Nearly a quarter of a century later, the science has moved on, but the book remains a classic.

The Evolution of Human Divers?

In southeast Asia, a group of extraordinary divers have plunged deep underwater to fish for centuries. A new study suggests they’ve adapted to their way of life, evolving larger spleens to deliver more oxygen. I wrote about the research last week for my column in the New York Times. (While the researchers I contacted for the story were impressed with the research, some scientists took to Twitter for a little critical post-publication peer review–see population geneticist Matthew Hahn and physiologist Michael Joyner.)

Hot Chimps

Oe a trip to Africa in 1995, I spent a few days in a cloud forest in Rwanda. There were chimpanzees around me, but I never got to see them. Only the seasoned experts at the field station could navigate the dense vegetation and catch glimpses of the apes. They became my personal icons of chimpanzees–creatures of the cool, wet canopy. But chimpanzees are more flexible than that. Some in Senegal live on a savanna that can hit 110 degrees. For my column this week, I wrote about a long-term study of these very different chimpanzees–and the hints they offer us about how our own ancestors abandoned forests for the open plains.

Nine years later, Erin Wessling can still remember the first time she visited Fongoli, a savanna in southeast Senegal.

“You feel like you walk into an oven,” she said.

Temperatures at Fongoli can reach 110 degrees Fahrenheit or more. During every dry season, brush fires sweep across the parched landscape, leaving behind leafless trees and baked, orange soil.

“It’s really nuts,” said Ms. Wessling, now a graduate student at the Max Planck Institute for Evolutionary Anthropology.
