At the same time, Sahara is green with rivers, lakes, cattle, crocodiles and monsoons. At 8 ka, Common (Bread) wheat ("Triticum aestivum") originates in southwest Asia due to hybridisation of emmer wheat with a goat-grass, "Aegilops tauschii". At 6.5 ka, two rice species are domesticated: Asian rice, "Oryza sativa", and African rice "Oryza glaberrima". Timeline of plant evolution This article attempts to place key plant innovations in a geological context. It concerns itself only with novel adaptations and events that had a major ecological significance,
Elasmopalpus brown anterior and distal margins. The larvae feed on a wide range of plants but prefer grasses. Recorded host plants include a number of economically important plants such as "Phaseolus vulgaris", "Beta vulgaris", "Brassica oleracea" var. "capitata", "Cucumis melo", "Cyperus esculentus", "Zea mays", "Vigna unguiculata", "Phaseolus lunatus", "Avena sativa", "Pisum sativum", "Arachis hypogaea", "Capsicum annuum", "Oryza sativa", "Secale cereale", "Sorghum bicolor", "Glycine max", "Sorghum sudanense", "Saccharum officinarum", "Ipomoea batatas", "Lycopersicon esculentum", "Brassica rapa" and "Triticum aestivum". They tunnel into the crown of their host plant, severely weakening large plants and often killing young seedlings. They spin silken tubes near the
