Your Genes Are Simply Not Enough to Explain How Smart You Are Seven years ago, I took a bet with Charles Murray about whether we’d basically understand the genetics of intelligence by now.

In 2018, Charles Murray challenged me to a bet: "We will understand IQ genetically—I think most of the picture will have been filled in by 2025—there will still be blanks—but we’ll know basically what’s going on." It's now 2025, and I claim a win. I write about it in The Atlantic.

Thank you very much for having me on today! Had a great time presenting my results about the adorable mouse lemurs.

Is it ok to acknowledge in papers funding opportunities that did not give you any $?

Like "We’d like to specially thank the NSX grant panel ABC for not giving us a cent and for pushing our creativity to a level we didn’t know we had—allowing us to complete this project with no funding"?

Sir David Attenborough’s latest film reveals the truth about bottom trawling — a fishing method that razes the seafloor like a bulldozer.

Sex differences in chimpanzees' use of sticks as play objects resemble those of children Sex differences in children's toy play are robust and similar across cultures [1,2]. They include girls tending to play more with dolls and boys more with wheeled toys and pretend weaponry. This patte...

Going on a limb here, but is it possible that Joker tried to imitate the adult females of the group instead of the males in his play behaviour? Because carrying sticks and stones on their back is popular play in young females, at least in chimpanzees.

Capuchin monkeys caught abducting baby howlers On Panama’s Jicarón island, biologists documented five male capuchin monkeys carrying at least eleven different infant howler monkeys—a behavior never before seen in wild primates.

On a remote Panamanian island, capuchin monkeys began kidnapping baby howlers and carrying them for days. Nobody was on the island to witness the origin and spread of this strange social tradition. But camera traps were there: www.ab.mpg.de/677569/news_...

Humans have many unusual traditions. But did you know animals’ strange behaviors can become culture too? Out now in Current Biology (doi.org/10.1016/j.cu...) we show the rise and spread of a surprising tradition: interspecies infant abduction. Interactive timeline (www.ab.mpg.de/671374) 🧵 (1/12)

Female solidarity keeps male bonobos in check Study on wild bonobos reveals that females team up to maintain power in their societies

Bonobo societies are famous for being “female dominant.” But females are weaker than males, so how can this be? Study by Barbara Fruth and Martin Surbeck on wild bonobos explains how.

Hint: it has to do with female solidarity.
