食性选择是动物行为的一个基本方面,是动物对影响因子响应的结果,具有重要的生态和进化意义。食性差异是动物适应性进化过程中的重要性状之一,也是决定动物多样性的关键因素之一。哺乳动物经历了丰富的食性变化,不同食性的哺乳动物在适应性进化过程中必然发生了与食性相适应的改变,故哺乳动物一直是研究动物食性进化机制的理想模型之一。通过基因组序列分析,DNA宏条形码技术,稳定同位素技术以及宏基因组技术等方法来追踪哺乳动物食性的转变机制,已揭示了部分因素与哺乳动物食性转变之间复杂的相互作用,为深入了解食性变化如何影响物种的适应和多样化奠定了基础。本文将从环境变化、基因调控以及肠道微生物三方面整合前人研究成果,系统阐明影响哺乳动物食性进化历程的关键因素,以期为深入理解动物多样性进化驱动力,合理制定多样性保护策略提供一定的参考。
