It is widely accepted Homo Sapiens are the dominant species of Modern Human although approximately 150 000 years ago the genus Homo Ferrum evolved and diverged from other hominids in Africa. While not as successfully abundant in numbers as Homo Sapiens they subsequently spread globally.
While the two species are similar in appearance and both have 23 pairs of chromosomes, DNA sampling can be used to identify homo type. This is generally unnecessary as characteristic traits of Homo Ferrum are easily identifiable by the time the child reaches the age of 5. Characteristics include lethargy, procrastination and an inhibited sense of smell. Physical differences include stronger back muscles and biceps than that of their closest living relative of Homo Sapiens. Because of these traits Homo Ferrum often choose careers as black smiths and farriers. Both species have lived peacefully together for many millennia as Homo Sapiens have adapted to accommodate the physical and behavioural differences of the Homo Ferrum. This is particularly apparent in the relationship between equestrians and farriers.
