形成6500万年了。根据最近一期出版的《科学》杂志刊登的两篇论文指出,根据最新科学研究,亚马逊热带雨林的形成和演变时间跨度长达6500多万年,其间地球急剧变暖有一定的影响作用。高温条件以及安第斯山脉的缓慢隆起是亚马逊地区生物多样性形成的主要原因。
65 million years. According to two papers published in the latest issue of Science magazine, according to the latest scientific research, the formation and evolution of the Amazon rainforest spanned more than 65 million years, during which the rapid warming of the earth played a certain role. High temperature conditions and the slow rise of the Andes Mountains are the main reasons for the formation of biodiversity in the Amazon region.
