英国布里斯托尔大学和开放大学的研究人员在《自然》杂志上发表论文指出,陆地上第一批大型捕食动物的进化成功,是由它们作为高效杀手的需要所驱动的。研究人员通过计算机建模分析了不同捕食性策略对食肉动物体型进化的影响。结果发现,相比吃腐肉,活捉猎物可以提供更丰富的食物来源,支持体型进一步增大。捕食者为适应陆地环境,进化出更敏捷灵活的身体,这加强了它们作为高效杀手的优势,从而推动了它们的进化进程。这一发现揭示了捕食行为在陆地大型食肉动物早期进化中的重要作用。
Title: Killer instinct drove the evolution of terrestrial predators
Keywords: Predator evolution, killer instinct, scientific research
News content: Researchers at the University of Bristol and the Open University in the UK published a paper in the journal Nature stating that the evolutionary success of the first batch of large terrestrial predators was driven by their need to be efficient killers. The researchers analyzed the impact of different predatory strategies on the body size evolution of carnivores using computer modeling. The results found that compared to eating carrion, capturing live prey can provide a richer food source to support further body size increases. To adapt to the terrestrial environment, predators evolved more agile and flexible bodies, which enhanced their advantage as efficient killers, thus promoting their evolutionary process. This finding reveals the important role of predatory behavior in the early evolution of large terrestrial carnivorous animals.
