Abstract

Numerous hypotheses have been advanced to explain the worldwide extinction event that led to the disappearance of the dinosaurs. There is considerable empirical support for the well-known asteroid impact hypothesis, and volcanic eruptions in the Deccan Traps have also been implicated. Increasingly, theories involving multiple causes are being considered, yet few of these consider how the cognitive and behavioral abilities of certain classes of animals may have differed in ways that allowed some to survive while others perished. Here we advance the hypothesis along with supporting evidence that the emergence of toxic plants coupled with an inability to form learned taste aversions may have contributed to the extinction of dinosaurs.

恐龙的灭绝和习得的味觉厌恶:生物复仇假说
人们提出了许多假说来解释导致恐龙灭绝的世界性灭绝事件。众所周知的小行星撞击假说有相当多的经验支持,德干圈闭的火山爆发也有牵连。越来越多的涉及多种原因的理论正在被考虑,但这些理论很少考虑到某些动物的认知和行为能力如何在某些方面有所不同,从而使一些动物存活下来,而另一些动物却灭亡了。在这里,我们提出了一个假设,并提供了支持证据,即有毒植物的出现加上无法形成习得的味觉厌恶可能导致了恐龙的灭绝。
