Homo ergaster (SciiFii)

The working human (Homo ergaster) is a species of human that originally lived in Africa during the Early Pleistocene and was once extinct, but has since been brought back from extinction by SciiFii. Unlike in prehistory, the working human is also found throughout Eurasia, the Americas, Australia, and New Zealand, due to the rapidly expanding populations of archaic humans relating to overabundance of food sources. The working human has a Homo sapiens-like gait and body proportions, and exhibits a flat face, prominent nose, and sparse body hair coverage. Though brain size certainly exceeds that of ancestor species, capacity varies widely depending on the population. In some populations, brain development seems to cease early in childhood, suggesting that offspring are largely self-sufficient at birth, thus limiting cognitive development through life. Nonetheless, the working human living in primitive tribes are known to consume medium to large animals, such as bovines or elephants, and is a result of the development of predatory behaviour and coordinated hunting. The working human is associated with the Acheulean stone tool industry, being able to make and use fire, perform hunting and gathering in coordinated groups, caring for injured or sick group members, and seafaring and art. The working human men and women are roughly the same size as each other (exhibit reduced sexual dimorphism) like modern-styled humans (Homo sapiens), which indicates monogamy in line with general trends exhibited in primates. Size, nonetheless, ranges widely from 146–185 cm (4 ft 9 in–6 ft 1 in) in height and 40–68 kg (88–150 lb) in weight. Skin colour varies with location. The working human is capable of speech, including proto-languages and, possibly due to genetic engineering, modern languages (including English, French, etc). The conservation status of the working human is Least Concern due to successful conservation efforts, the working human's wide range and its tolerance to most of human activities caused by Homo sapiens, so it is able to become part of civilization alongside Homo sapiens.
