fear causes extinct

 

恐懼或會影響動物種群的數量減少及滅絕。研究發現,捕食者如螳螂的氣味會使果蠅恐懼,令牠們更加警惕並縮短進食時間,而且會令交配次數下降,導致數量減少。

fear could cause decline and extinction to a species. study found the smell of predators like a mantis could bring fear to fruit flies. the flies then become more alert and spend less time eating; they also spend less time mating and so produce fewer offspring.
