The mutualism between chemical cues emitted into the air and variations in how primates respond to them using olfaction has demonstrated aspects of species-specific adaptations. Building on this mutualism we can look at particle deposition as another means to understanding how various environments may have elicited biological changes that enable efficient communication. Research on particle movement and deposition within the nasal cavity is largely based on questions about health as it relates to drug delivery systems and overall olfactory function in modern humans. With increased access to 3D models and the use of computational fluid dynamic analysis, researchers have been able to simulate site-specific deposition, to determine what particles are making it through the nasal cavity to the main olfactory epithelium, which ultimately leads to processing in the olfactory bulb. Here we discuss particle deposition research, sensory drive and their potential applications to evolutionary anthropology.
空气传播的化学信号与灵长类动物嗅觉反应的变化之间的共生关系，揭示了物种特异性适应的一些方面。在此共生关系的基础上，我们可以将颗粒沉积视为另一种理解不同环境如何引发生物学变化从而实现有效沟通的手段。关于鼻腔内颗粒运动和沉积的研究主要基于与健康相关的问题，如药物输送系统和现代人类嗅觉功能的整体情况。随着对 3D 模型的广泛应用和计算流体动力学分析的使用，研究人员已经能够模拟特定部位的沉积，以确定有哪些颗粒通过鼻腔到达主嗅觉上皮，而这最终会导致嗅觉球的处理。在这里，我们讨论颗粒沉积研究、感觉驱动及其在进化人类学中的潜在应用。
