  Not rainforest, but rather savanna [1]. The Arabian desert is technically considered to be part of the Sahara, climate-wise, and participes in the same cycle [2]. This article is about researching evidence for ehat those transitions looked like, focusing on evidence that dates around the end of that particular dry period, pre-Holocene. > Prior to the onset of the Holocene humid period, little is known about the relatively arid period spanning the end of the Pleistocene and the earliest Holocene in Arabia. An absence of dated archaeological sites has led to a presumed absence of human occupation of the Arabian interior. However, superimpositions in the rock art record appear to show earlier phases of human activity, prior to the arrival of domesticated livestock25.
