An informal term for the most human-like primates, the bipedal apes, as opposed to apes in general. They are similar to other advanced primates in terms of their genetic makeup and are distinguished culturally (most markedly in Homo sapiens) by their more extensive creation of technology, including art and language. They also have certain common physiological traits such as hairlessness, erect posture, and fine manipulation (precision grip). Human baselines were the only surviving members of this group on Old Earth prior to various lazurogenic efforts.

- Homo Economicus
- Homo erectus - Text by M. Alan Kazlev
Early Pleistocene hominid that evolved in Africa about 1.6 million years ago and developed fire, clothing, language, and weapon use (see also acheulian technology). A direct ancestor leading to Homo sapiens. The species has been successfully lazurogened by hyperturing hobbyists a number of times.
- Homo habilis
- Homo neanderthalensis - Text by M. Alan Kazlev
Pleistocene hominid that evolved from Homo erectus about 100,000 years ago in Europe and the Middle East. A cousin rather than an ancestor to Homo sapiens, Homo neanderthalensis was short, stocky, and powerfully-built, and perfectly physiologically adapted to the harsh conditions of ice-age Europe, e survived with almost no change for some 70,000 years. E developed a culture that included elaborate funeral rituals, burying their dead with ornaments, caring for the sick, and making tools for domestic use and for protection. Homo neanderthalensis disappeared about 35,000 to 40,000 years ago, being unable to compete with Homo sapiens. A few of the Children of Gaia are said to be Neanderthal Rianths, and the genotype is popular among some clades in the Utopia Sphere and elsewhere.
- Homo sapiens - Text by M. Alan Kazlev
Large-brained hominid species that emerged perhaps 400,000 years ago (Heidelberg Man, etc.). Homo sapiens evolved from Homo erectus and eventually replaced Homo neanderthalensis to become the sole hominid species and subspecies. Includes thousands of subspecies, almost all of which date from post-Interplanetary period.
- Homo sapiens species group - Text by M. Alan Kazlev
A large and diverse group of hominid species that include Homo sapiens and many similar forms. See also Near-Baseline.
