Another explanation for the disappearance of dinosaurs ...
Researchers propose that those who were once the kings of the Earth disappeared because they were unable to distinguish toxic plants, some 65 million years ago, in Mexico ... As they explain, the appearance of toxic plants combined with the inability of dinosaurs to associate the taste of certain foods with the danger was actually what put them in the pillory. These circumstances had already drastically reduced the population of dinosaurs when the asteroid crashed.
The "aversion to learned taste" is an evolutionary defense that is observed in many species, by which the animal learns to associate the consumption of a plant or other food with negative consequences, such as feeling sick. To explain the defense mechanism, evolutionary professor and psychologist Gordon Gallup, gives the example of rats.
