Az evolúció legképtelenebb, sületlen, hagymázos ötlete minden kétséget kizáróan az ember, becenevén a Homo sapiens. Öt-hatmillió éve a bioszféra üde színfolt lehetett a bolygón sokféle állattal és növénnyel, az ökológiai rendszer kiegyensúlyozott volt, és úgy tűnhetett, hogy megalapozott, tartós jövője sok százmillió évre biztosítva van. És ekkor a rendszer finom, olajozott kerekei közé por, autóroncsok, enzimes mosópor került. Recsegés, ropogás, füst és korom. Mi történt?

In the mid- to late-19th century, a burgeoning science called electricity promised to shine new light on a rousing nation. Inventive and ambitious minds were hard at work. Soon that spark was fanned, and a war was under way to be the first to light - and run - the world with electricity. Thomas Alva Edison, the inventor of direct current (DC), engaged in a brutal battle with Nikola Tesla and George Westinghouse, the inventors of alternating current (AC). There would be no ties in this race - only a winner and a loser - and the prize was a nationwide monopoly in electric current.

Warum sind wir Menschen so verschieden? Sind wir nicht merkwürdig, wir Menschen, mit verschiedenartigem Aussehen, anderen Sprachen und unterschiedlichen Religionen? Der Evolutionsbiologe Josef H. Reichholf greift das Thema Evolution anhand der alltäglichen Erfahrungen auf, die junge Menschen z.B. bei ihren Mitschülern machen: Jeder Einzelne ist anders, dazu kommt die äußerliche Verschiedenheit durch Kinder asiatischer oder schwarzafrikanischer Herkunft.
