Let us all thank messy eaters
Researchers at the Arizona State University Institute of Human Origins have found that our species’ first ancestors began to climb down from trees to retrieve snacks they had dropped. Anatomical evidence from the 6-million-year-old fossilized remains of Sahelanthropus peinaó—which was unearthed earlier this year in South Africa and is now believed to be the last common ancestor shared by chimpanzees and modern humans—suggests that the animal frequently descended from the jungle canopy to retrieve food that fell from its hands owing to inattention, overeager eating, or a loosening grasp as it dozed off after a meal.
According to the researchers, everything humans have accomplished as a species—from “colonizing every corner of the planet, to building the Colosseum, to walking on the surface of the moon”—can be traced back to that first human forebear “sweating and breathing heavily as it struggled down a tree trunk” to recover a snack .
At some point in the Miocene epoch, one of the hominids realized that if it wished to continue snacking, it would have to come down from the tree, wander out onto the savanna, pick the morsel up, and put it back in its mouth. This was the impetus for several other key adaptations, including the increased brain size and cognitive capabilities that are the hallmarks of Homo sapiens. They began gradually developing the ability to form abstract thoughts—including planning, problem-solving, projecting into the future, and evaluating alternative options—as they grasped the notion that if they did not retrieve the food they would go hungry. Moreover, complex human emotions, from regret to longing to a desire for remediation, are also said to have begun emerging as humans began to reflect on the meals they dropped.
Speech arose from the grumbling about having to climb down the tree. The hominids’ final shift to becoming an exclusively ground-dwelling species is said to have occurred roughly 5 million years ago when, having finished the snacks they had retrieved, they looked at the trees, realized what a hassle it would be to climb all the way back up there, and opted instead to take a nap on the ground.
Does all this really matter? Not really, but it takes your mind for a moment off the world political situation! That’s what Epicurus would have advised us to do – if possible.

Warning: don’t fall in love with a foreigner
The Tories pride themselves on being “family-friendly”, says Giles Fraser. Yet their belief in nurturing this precious institution doesn’t extend to “those of us who fall in love with foreigners”. Under a policy introduced in 2012 – and upheld last week by the Supreme Court – Britons applying to bring a non-EU partner or spouse to live with them in the UK must earn at least £18,600 a year. So no problems for the Queen and Prince Philip, and an effective bar to “scam marriages set up for money, or lonely men conned into acquiring mail-order brides from Belarus over the internet”. But what about the rest of us? Nearly 40% of Britain’s working population, and a majority of its young people, earn less than that; in which case you and your partner either have to live apart or “shove off and set up family life elsewhere”. When my foreign-born wife and I went to a registry office to set a date for our marriage, we were interrogated as if we were “smuggling heroin though passport control”. The UK is now “the least-welcoming country to mixed-nationality couples in the Western world”. (Giles Fraser, The Guardian).
Returning from France a year or two ago, my wife, who is American, had a very unpleasant conversation at UK passport control in Paris with a very aggressive official. She was reluctantly allowed into England, but even though she is legally allowed to be there for up to six months in a year. The effect of this sort of treatment is discouraging for those who, not contemplating immigration, are simply visiting for more than a week or two (we were staying 4 months). At one point we talked about her staying in England for several years as my spouse, in order to apply for British citizenship. For various reasons we never did it, but now the time has passed – it is just too difficult, queueing at the Croydon office being just a small part of the problem. Britain, once uniquely open-minded and well-informed about the people and politics of foreign countries, is perceived to be suspicious and sometimes even hostile to foreigners, taking its cue from the right-wing Tories, “cabin’d, cribbed, confined, bound in by saucy doubts and fears”.
