Why did the berbers start using camels instead of donkeys and horses when transporting goods across the desert? a. donkeys and horses became very difficult to find. c. a camel’s natural features, such as their soft pad feet and ability to store fat within its hump, allow the camel to travel more efficiently through the dessert. b. camels’ legs are longer than those of a horse or a donkey, so camels were able to move faster than donkeys or horses. d. camels were used because they were also part of the trade system. after to tow other goods the camels could also be sold.
