牙本质起源于古鱼外骨骼中的感觉组织
芝加哥大学的一项新研究表明,牙本质——即牙齿的内层,负责将感觉信息传递到牙髓内的神经——最初是作为古代鱼类装甲外骨骼中的感觉组织进化而来的。对于牙齿如何起源,有两种观点。一种是“由内而外”假说,认为牙齿先出现,后来才适应外骨骼。新研究支持第二种“由外而内”假说,该假说认为敏感结构首先在外骨骼上发育,并且在某个时期,动物也利用相同的基因工具产生了敏感的牙齿。
In today’s rapidly evolving threat landscape, Security Information and Event Management (SIEM) and Security Orchestration, Automation, and Response (SOAR) platforms have become foundational to organizational cybersecurity strategies. SIEM platforms collect, centralize, and analyze log data from diverse sources, such as endpoints, servers, cloud services, and network devices, using correlation rules and filters to detect anomalous […]
