Nabta Playa was once a large basin in the Nubian Desert, located approximately 800 kilometers south of modern day Cairo or about 100 kilometers west of Abu Simbel in southern Egypt… Today the region is characterized by numerous archaeological sites…Archaeological findings may indicate human occupation in the region dating to at least somewhere around the 10th and 8th millennia BC…By the 5th millennium BC these peoples had fashioned one of the world’s earliest known archeoastronomical devices (roughly contemporary to the Goseck circle in Germany and the Mnajdra megalithic temple complex in Malta). Research suggests that it may have been a prehistoric “calendar” marking the summer solstice.
Many plants and their pollinators co-evolved specialized adaptations that aid pollination. But researchers recently found that a short-nosed bat bests its more specialized cousin at pollinating cactus.
