本文的目的是研究西班牙和东非新近纪的哺乳动物群，以了解这两个地区新近纪动物群之间的关系。现有数据表明，在新近纪，伊比利亚和东非之间的动物区系相似性变化很大，有时相似性相对较大（共同属的数量较多），有时相似性较弱（共同属的数量较少）。动物区系相似性的变化似乎是有关的纬度波动的位置的边界的原始埃塞俄比亚和原始古北动物地理领域。动物群相似性较大的时期与边界区的偏北位置相吻合，而动物群差异较大的时期则发生在边界区位于偏南位置时，就像今天一样。我们把动物地理界之间边界地带位置的这些变化与影响地球仪的大地构造、气候和天文变化联系起来。
The aim of this paper is to examine the mammalian faunas of the Neogene of Spain and of East Africa with a view to understanding the relationships between the Neogene faunas of the two regions. The available data indicates that during the Neogene, faunal similarities between Iberia and East Africa varied greatly, at times the resemblances being relatively great (high number of genera in common), at others the similarities being weak (low number of genera in common). Changes in faunal similarity appear to be related to latitudinal fluctuations in the position of the boundaries of the Proto-Ethiopian and Proto-Palaearctic zoogeographic realms. Periods of greater faunal similarity coincide with a northerly position of the boundary zone, while periods of greater faunal dissimilarity occur when the boundary zone is located in a southerly position, as it is today. We related these changes in the position of the boundary zone between zoogeographic realms to geotectonic, climatic and astronomic changes which affected the globe.
