The historical past of technology abounds with momentous theories that disrupted traditional knowledge and but have been ultimately confirmed precise. Ajit Varki and Danny Brower's "Mind over Reality" concept is poised to be one such idea-a idea that runs counter to commonly-held notions approximately human evolution yet which may carry the major to knowing why people developed as we did, leaving all different similar species a long way behind.

At an opportunity assembly in 2005, Brower, a geneticist, posed an strange notion to Varki that he believed might clarify the origins of human distinctiveness one of the world's species: Why is there no humanlike elephant or humanlike dolphin, regardless of thousands of years of evolutionary chance? Why is it that people by myself can comprehend the minds of others?

Haunted by means of their come upon, Varki attempted years later to touch Brower basically to find that he had died all of sudden. encouraged via an incomplete manuscript Brower left at the back of, DENIAL provides a thorough new concept at the origins of our species. It was once now not, the authors argue, a organic jump that set humanity except different species, yet a mental one: specifically, the uniquely human skill to disclaim fact within the face of inarguable evidence-including the willful lack of knowledge of our personal inevitable deaths.

The expertise of our personal mortality may have prompted anxieties that led to our keeping off the hazards of competing to procreate-an evolutionary dead-end. people consequently had to evolve a mechanism for overcoming this hurdle: the denial of reality.

As a outcome of this evolutionary quirk we now deny any facets of truth that aren't to our liking-we smoke cigarettes, devour dangerous meals, and stay away from workout, figuring out those behavior are a prescription for an early dying. And so what has labored to set up our species will be our undoing if we proceed to disclaim the implications of unrealistic methods to every little thing from own future health to monetary risk-taking to weather switch. nevertheless reality-denial provides us many worthwhile attributes, reminiscent of optimism, self belief, and braveness within the face of lengthy odds.

Presented in homage to Brower's unique pondering, DENIAL bargains a strong caution concerning the hazards inherent in our striking skill to disregard reality-a present that would both bring about our downfall, or stay our best asset.

Example text

Bei Belding-Zieseln (Spermophilus beldingi) der nordamerikanischen Sierra Madre hat das infantizidale Verhalten von Weibchen einen weiteren funktionalen Hintergrund. Hier geht es nicht vorrangig um verbesserte Ernährung, sondern um Territorialgewinn. Die Weibchen dieser Art werfen je nach Alter drei bis acht Jungtiere pro Saison und ziehen diese in einem System benachbarter Erdhöhlen auf. Rund vier Wochen nach der Geburt sind die Jungtiere entwöhnt und erscheinen im Freien. Innerhalb der ersten vier Lebenswochen führen sie jedoch ein ziemlich risikoreiches Leben, denn mindestens 8 % von ihnen werden in dieser Zeit von Artgenossen getötet.

Als »Infantizid« bezeichnet man das Töten noch nicht entwöhnter (bzw. noch nicht flügge gewordener) Jungtiere, während sich »Pädizid« auf die Tötung älterer Kinder bezieht. Im Folgenden soll der Einfachheit halber der Begriff Infantizid auch als gemeinsamer Oberbegriff verwendet werden. 2).
