Isn't it romantic?

Male chimpanzees in West Africa raid fruit from farms and orchards to share with females. In most cases, the males shared their booty with reproductive females in a food-for-sex swap. PLoS One.

Simian crime and punishment

Chimpanzees take revenge upon one another, but only if it doesn't cost them. Humans, however, will inflict suffering on themselves in order to punish someone else. It may be that our willingness to punish others even if it hurts us is as important to the evolution of human society as our ability to cooperate with each other.

This week's PNAS describes an experiment where a chimpanzee that has access to a rope which can collapse a table with food on it (sending the food onto the floor and out of reach of all chimpanzees) will yank the rope 30% of the time if it can see the food but not reach it, or if it cannot reach the food itself but can see another chimpanzee eating it. It will yank the rope significantly more if another chimpanzee has pulled the food out of its reach. What chimpanzees won't do is send the food to the floor to punish another chimpanzee if they themselves are eating. New Scientist, Science Now.

Two of the researchers behind these findings, Josep Call and Michael Tomasello, appear in The First Word. Tomasello was also behind the research on generosity in humans and chimpanzees, reported in the July 8 post.

BOOK



  • A Los Angeles Times Book Prize finalist, The First Word is about the quest for the origins of human language. Although language is a distinctly human gift, it leaves no permanent trace and its evolution has long been a mystery. It is only in the last fifteen years that we have begun to understand how language came into being. The First Word follows two intertwined narratives. The first is an account of how the random and layered processes of evolution wound together to produce a talking animal: us. The second addresses why language evolution was considered a scientific taboo for more than a hundred years and why scientists are at last able to explore the subject.

  • from THE NEW YORKER
    "[An] accessible account... including many provocative findings."
  • from THE BOSTON GLOBE
    "Kenneally's reporting and interpretation of this research, whose implications for the study of language and human nature are immense, occupy center stage in 'The First Word' and generate real excitement on the page."
  • from THE CHARLOTTE OBSERVER
    "...a cogent and often compelling account... As Kenneally dissects each scholar's theory, a wonderful evolution occurs on the pages: She explains, understatedly, what it means to be part of human nature."
  • from SCIENTIFIC AMERICAN
    "...an elegant exposition."
  • from THE NEW YORK TIMES
    [A] lucid survey of this expanding field... covers an enormous expanse of ground as she brings the reader up to date on developments in a wide variety of disciplines touching on language evolution... explains difficult ideas concisely and clearly... scrupulously fair-minded... zeroes in on a host of fascinating experiments.
  • from THE NEW YORK TIMES BOOK REVIEW
    "[The] scientists who study the origins of language are a passionate, fractious bunch, and you don’t have to be an egghead to be tantalized by the questions that drive their research: how and when did we learn to speak, and to what extent is language a uniquely human attribute?... Much of what [Kenneally] describes is fascinating."

    Chimpanzees are smarter than humans. Orangutans are smarter than chimpanzees. Humans are smarter than chimpanzees. Which of these statements is true?

  • Thank you Rod Stewart. Seriously.
    There's an unexplained mystery about the length of women's lives. Once their ability to have children shuts down, there is no obvious reason for their biology to resist all the forces that conspire to take them down. Indeed, according to demographic models, women over 50 should hit a "wall of death." But they don't. Why not?
