In a rare political riposte, Senator Elizabeth Warren on Monday released an analysis of her DNA indicating that she has a Native American ancestor, likely between six and 10 generations back in her family history.

President Trump has mocked Ms. Warren’s claims of Native American ancestry, often calling her Pocahontas. The new analysis appeared to be scientifically rigorous, researchers said, but it cannot give someone a cultural identity as Native American.

The research on Ms. Warren’s DNA was led by Carlos Bustamante, a Stanford University geneticist who has written a number of studies on the genetic ancestry of people in the Americas. The results were first reported by the Boston Globe.

Forests have burned in spectacular fashion this year. From California to ColoradoPortugal to Greece, photographers have captured terrifying images of infernos soaring into the sky and spreading to the horizon.

The fires left scenes of ashen destruction, but they did not wipe out everything. Scattered about the ravaged landscapes were islands of trees, shrubs and grass that survived unharmed.

It’s easy to overlook these remnants, which ecologists call fire refugia. But they can be vital to the long-term well-being of forests. These havens shelter species that are vulnerable to fires. Afterward, they can be starting points for the ecosystem’s regeneration.

Happy First Friday!

September hurried by in a rush as I zipped around for much of the month. One of my favorite stops along the way was the lovely English city of Bath. I traveled to the university there for a conference to celebrate the opening of the Milner Centre for Evolutionary Biology. The University of Bath has long been a powerhouse for evolution research, and I expect the new center will up their game even more.

For two days, we listened to talks on topics ranging from the evolution of deadly bacteria to the Cambrian explosion to Darwin’s finches to the domestication of dogs. At the end of the conference, I moderated a panel on the future of evolution research, talking with Patrick Goymer from Nature Ecology and Evolution, Aiofe McSlayt from Trinity College Dublin, Michael Purgannan of New York University, Roli Roberts from PLOS Biology, Nina Waddell of the University of Exeter.

They agreed that the science of evolution has been profoundly accelerated by DNA sequencing. It’s now possible to put hypotheses to the test that until now were practically untestable. As a result, a lot of arguments are getting resolved, and evolution is becoming more and more of an applied science—helping to explain precisely how HIV becomes resistant to antivirals, for example, or determining the best way to treat cancer.

While the technology we talked about might be new, it struck me that the concepts were not. The researchers talked about things like natural selection, genetic drift, character displacement, adaptive radiation—concepts that have been part of the language of evolutionary biology for decades. When I asked if the future of evolutionary biology was going to see the emergence of new concepts, the panelists shrugged their collective shoulders. They considered the conceptual toolkit of evolution to be in good shape.

More News about She Has Her Mother’s Laugh

A big highlight of the month was learning that She Has Her Mother’s Laugh is on the shortlist for the Baillie Gifford Prize, Britain’s top prize for nonfiction books! The winner will be announced next month. The web site Five Books interviewed one of the judges about their choices. I’m looking forward to reading clear the other books on the shortlist.

In other book news…

I spoke to BBC about heredity.

PBS put together a nice video about the inheritance of height, based on a chapter from the book.

The Beagle Has Landed, a podcast about clinical genetics, interviewed me about She Has Her Mother’s Laugh.

And, last but not least, it was a surreal delight to find David Quammen, a writer I deeply admire, posting a picture of my book on Twitter, posed with a tumbler of a whiskey and a python.

Colorado, Massachusetts and more: October’s Talks

For reasons unknown, I am rushing around to a bunch of talks this month–a few of which fell into place just recently. Here are the details for October. (Full calendar at the end, as usual.)

On Tuesday, October 9, I’ll be at New York University for an event called “Why You’re You: Explaining Heredity to a Confused Public.” I’ll be talking with Jennifer Raff, an anthropologist at the University of Kansas, and Wall Street Journal science writer Lee Hotz.

The next day, Wednesday, October 10, I’ll be at Yale Law School to talk about the science of science communication. Why is it that science news or a visit to the doctor can change the way some people think but not others? Why is global warming controversial, but lasers aren’t? I’ll be discussing these issues with Dan Kahan and Kathleen Hall Jamieson, two of the leading researchers in this field, and Sarah Smaga, a Yale graduate student who dedicating a lot of her efforts to science outreach.

A week later, on Wednesday, October 17, I’ll be talking about She Has Her Mother’s Laugh at Colorado State University as a Murray Honors Visiting Scholar Lecture.

On October 19, I’ll be in Las Vegas to talk about heredity and its misconceptions at CSICon.

And, finally (for October), I’ll be speaking at Mount Holyoke College on October 23.

Jellyfish and Borrowed Neanderthal Genes

My batch of New York Times columns in September runs the biological gamut:

Chimps and bonobos are generous–up to a point. And being human means going beyond that point.

We don’t know much about most of our genes–and that’s a problem.

Jellyfish: It’s what’s for dinner

Neanderthals may have given us the flu, or viruses like it

People of Asian and European descent — almost anyone with origins outside of Africa — have inherited a sliver of DNA from some unusual ancestors: the Neanderthals.

These genes are the result of repeated interbreeding long ago between Neanderthals and modern humans. But why are those genes still there 40,000 years after Neanderthals became extinct?

As it turns out, some of them may protect humans against infections. In a study published on Thursday, scientists reported new evidence that modern humans encountered new viruses — including some related to influenza, herpes and H.I.V. — as they expanded out of Africa roughly 70,000 years ago.

For a hungry fish in search of a meal, a jellyfish would seem to be a huge disappointment. These gelatinous animals are 95 percent water. As a result, a cup of live jellyfish provides just five calories — one-third the amount in a cup of celery.

It should come as no surprise, then, that marine biologists long ago dismissed jellyfish as an insignificant item on the ocean menu. Other animals rarely bothered eating them, the idea went, and so they represented a dead end in the ocean’s food web.
