Camels
Dromedary camels were first domesticated by the Berbers in 300 CE. They were and still are very popular in the northern part of Africa and were used to convey goods and people from one end of the desert to the other. They were most appropriate for this use because they can survive perfectly under harsh heat and in dry regions.
Camels were grouped into caravans and were used to move very large items. As many as 1,000 to 10,000 camels could line up guided by humans and led to their destinations. Some of the caravans were connected by ropes from one camel to the other to prevent a break in the chain.
