Our knowledge about the origin of landbirds (Telluraves) is increasing rapidly but new questions are arising because of the contradictory findings from previous studies. All of the major lineages in the highly diverse clade of Neoaves have a Gondwanan origin, although studies often disagree about the origin of different sub-lineages. Nevertheless, understanding the biogeographical histories of these groups (e.g. Accipitriformes, Passeriformes) is important when studying the evolution of variation in life history and behavioural traits. Therefore, we would like to find answers to questions such as which biogeographic changes affected the radiation of birds? When did the most influential climatic events affect the diversification of birds? What behavioural adaptations occurred in response to those large-scale changes? The major orogenetic events in Asia and South America formed specific corridors that enabled the radiation of birds. The climatic changes and habitat differentiation they caused during the Oligocene-Miocene era made the divergence of birds possible through their adaptation to newly available niches. Consequently, variation in life history and behavioural traits emerged as adaptive outcomes of changes in foraging, nestling and migratory behaviours.
我们对陆禽(Telluraves)起源的了解正在迅速增加,但由于先前研究的相互矛盾的发现,新的问题不断出现。尽管研究经常不同意不同亚系的起源,但新鸟亚纲这个高度多样化的分支中的所有主要谱系都起源于冈瓦纳大陆,理解这些群体(如鹰形目、雀形目)的生物地理历史对于研究生活史和行为特征变化的进化非常重要。因此,我们希望找到以下问题的答案:哪些生物地理变化影响了鸟类的辐射?最重要的气候事件何时影响了鸟类的多样化?为了应对这些大规模变化,发生了哪些行为适应?亚洲和南美洲的主要造山运动形成了特定的走廊,使鸟类得以辐射。它们在渐新世-中新世期间引起的气候变化和生境分化,使鸟类通过适应新出现的生态位而得以分化。因此,生活史和行为特征的变化是觅食、育雏和迁徙行为变化的适应性结果。
