The new data suggest that the glutamate receptors and other similar neuro - transmitter receptors may actually evolve from ancestral methods of simple communication , common to plants and animals alike . selective environmental pressure may have led to a higher production of these neurotoxins for defense against predators more recently in evolutionary time . neurotoxins isolated from plants may be originally signalling molecules regulating these plant receptors 林教授指出以往生物学家相信植物制造神经毒素纯是为了防御草食类动物的侵袭，但这项植物?氨酸感受器的研究却指向另一可能性，即神经毒素最初可能是植物用来作讯息传递的分子，通过?氨酸感受器和其他类似的感受器来调控植物本身的生命功能。
