Ethiopia from the perspectives of biodiversity and crop origin, Ethiopia is believed to be a land of topographic diversities  and home of multiple ethnic groups . Moreover, it is known to be a land for the origin of both human kind and plants (Alemayehu Kefalew and Sara Sintayehu, 2017). Globally Ethiopia is known to be part of biodiversity hotspot area. Below (Figure 1), the red marks, are Earth’s biologically richest places with high number of species found nowhere else, and one of which is Ethiopia.

Archaelogical and Anthropological study showed that Ethiopia is also an important source of crop origin/diversity. In fact center of crop diversity and origin of agriculture were described first by Alphonse De Candolle  saw wild relatives of the major crops such as wheat, beans, rice. He proposed that the crops of the world originated in three centers.
2. The Fertile crescent of the Middle East.
3. Southeast Asia. The criteria he used for recognizing centers of origin were:
a) Places where a plant grows spontaneously in the wild state.
b) Places where fragments of plants in old deposits and buildings (Archaeobotanical and Paleo botanical) are found.
c) Archives describing the adventures of travelers.
d) Philogical (naming) origin.
The other notable scientist who made thorough investigation on crop origin was NI Vavilov . He was a Russian germplasm collector and genetists. He studied the genetics, chromosome and anatomy of the germ plasm of crops he collected from five continents. Based on his studies he concluded that the most likely areas of origin were where the plant was cultivated and the wild ancestors grew . Furthermore, according to Vavilov , the areas of Origin should be areas in which there was lots of variation. He was interested to see where can find wild ancestors of crops. Moreover, apart from his botanical explorations he also used evidences from archaeological excavations. In 1951 he published studies on the origin of cultivated plants which describes his theories on the origin of crops. Accordingly Ethiopia has been suggested to be the center of Crops such as Coffee (Coffeaarabica), TEFF (Eragrostistef), ENSET (Ensetventricosum), NOUG (Guizotiaabyssinica), ANCHOTE (Cocciniaabyssinica), etc as they were/are found in nature on the land of Ethiopia. The following map illustrates areas of crop origin according to Vavilov , (Figure 2).
