Near-Human is the general term for any of the many species or subspecies in the galaxy which are very closely related biologically to baseline Humans. In contrast, other humanoid species only had general external similarities to Humans, and had no biological connection. However, the term "humanoid" is sometimes used loosely to describe Near-Human species. Most Near-Humans shared close external similarities to Humans, usually with small differences in skin and eye color or bone structure. Biologically, many Near-Humans are capable of interbreeding with baseline Humans. Some were close enough to the Human baseline to be considered a race or ethnic group of Humans, rather than a separate species. Similarly, some groups, biologically classified as Humans, though differing from the Human mainstream almost entirely in their culture, were considered so distinct that they were sometimes referred to as Near-Human.
