Ist Güte natürlich?

Es ist schwer vorstellbar, dass jemand Güte für ein Problem halten würde – Charles Darwin tat dies jedoch. Die kleinen Arbeitsbienen, die sich selbst opferten, um ihre Bienenstöcke zu schützen – das ultimative Beispiel für Güte im Tierreich –, ließen Darwin nachts keinen Schlaf finden.

Wenn Darwins Vorstellungen zur Evolution durch natürliche Auslese richtig waren (und das waren und sind sie selbstverständlich), dann sollte diese Art Altruismus in der Natur außerordentlich selten vorkommen. Wenn eine erhöhte Fortpflanzung das absolut Wichtigste in der Evolution durch natürliche Auslese ist, dann müssten Altruisten aussterben – und zwar schnell. Doch sterben sie nicht aus, und Darwin war darüber so verwundert, dass er vom Altruismus als einem Problem sprach, das sich als fatal für seine gesamte Evolutionstheorie erweisen könnte.

Dann traf die Lösung dieses tückischen Rätsels Darwin wie ein Blitzschlag. Die Arbeitsbienen halfen nicht einfach irgendwelchen Bienen; sie schützten ihren Bienenstock. Und in ihrem Bienenstock lebten besondere Bienen: Blutsverwandte.

  3. Murdoch's Last Stand?

    Rupert Murdoch’s sale of 21st Century Fox’s entertainment assets to Disney for $66 billion may mark the end of the media mogul’s career, which will long be remembered for its corrosive effect on democratic discourse on both sides of the Atlantic. 

    From enabling the rise of Donald Trump to hacking the telephone of a murdered British schoolgirl, Murdoch’s media empire has staked its success on stoking populist rage.

    The Dangerous Delusion of Price Stability

    Since the hyperinflation of the 1970s, which central banks were right to combat by whatever means necessary, maintaining positive but low inflation has become a monetary-policy obsession. But, because the world economy has changed dramatically since then, central bankers have started to miss the monetary-policy forest for the trees.

  5. Harvard’s Jeffrey Frankel Measures the GOP’s Tax Plan

    Jeffrey Frankel, a professor at Harvard University’s Kennedy School of Government and a former member of President Bill Clinton’s Council of Economic Advisers, outlines the five criteria he uses to judge the efficacy of tax reform efforts.

But ensuring that those changes are positive – helping to fight tumors and mosquito-borne illnesses, for example – will require scientists to apply the utmost caution.
