Interview: Frans de Waal, primatologist

SEX and gender have come to represent one of the hottest fronts in the modern culture wars. Now, on to this bloody battlefield, calmly dodging banned books, anti-transgender laws and political doublespeak, strolls the distinguished Dutch-American primatologist Frans de Waal, brandishing nearly half a century’s worth of field notebooks and followed, metaphorically speaking, by an astonishingly diverse collection of primates…

The big idea: should other species have their own money?

ONLY about 120,000 orangutans remain in the wild, and despite the whopping $1bn that has been spent on protecting them since 2000, their numbers continue to decline. The orangutan is the most endangered great ape, but the picture is only marginally less grim for the others – except us, of course – and the trend is the same across the living world: we’re witnessing a sixth mass extinction. Given that current conservation efforts aren’t working fast enough, many feel it is time for some out-of-the-box thinking. It doesn’t come much further out than giving other species their own money, but that proposal is now on the table. The first to benefit might be our intelligent, red-haired cousins…

Womanland

THERE can be few myths as ingrained in our consciousness as that of the Amazons, an ancient caste of warrior women whose marksmanship struck fear into the hearts of their enemies, who chose sexual partners freely and who sacrificed their male offspring to preserve the matriarchy…

Epigenetics, the misunderstood science

A little over a decade ago, a clutch of scientific studies was published that seemed to show that survivors of atrocities or disasters such as the Holocaust and the Dutch famine of 1944-45 had passed on the biological scars of those traumatic experiences to their children.

The studies caused a sensation, earning their own BBC Horizon documentary and the cover of Time (I also wrote about them, for New Scientist) – and no wonder. The mind-blowing implications were that DNA wasn’t the only mode of biological inheritance, and that traits acquired by a person in their lifetime could be heritable. Since we receive our full complement of genes at conception and it remains essentially unchanged until our death, this information was thought to be transmitted via chemical tags on genes called “epigenetic marks” that dial those genes’ output up or down. The phenomenon, known as transgenerational epigenetic inheritance, caught the public imagination, in part because it seemed to release us from the tyranny of DNA. Genetic determinism was dead…

The Code Breaker by Walter Isaacson – review

ONE of the most striking passages in Walter Isaacson’s new book comes towards the end. It is 2019 and a scientific meeting is under way at the famous Cold Spring Harbour Laboratory in New York State, but James Watson, the co-discoverer of the structure of DNA, is banned from it because of the racist and scientifically unfounded views he has expressed on intelligence. Isaacson, who is to interview Watson, therefore has to make his way to the house on the nearby campus that the scientist has been allowed to keep. When the conversation sails dangerously close to the race issue, someone shouts from the kitchen: “If you are going to let him say these things, then I am going to have to ask you to leave.” The 91-year-old Watson shrugs and changes tack…
