Warm-blooded, furry (or secondarily hairless) Terragen animals that suckle their young. Together with birds they have been the most successful form of Terragen land vertebrate life during the Cenozoic era, though they had a long prior history in the preceding Mesozoic as well. The clade includes hominids, apes, bats, cats, dogs, dolphins and whales, rodents, ungulates, and many other well known groups. Baseline or gengineered subsophont mammals are particularly easy and popular to provolve because of their often sociable nature, their long nurturing period and their large brains.

It might be said that all sophont Terragens are in some sense descended from mammals, since baseline humans are mammals and humans have rise to the cultures and technologies that made all the other clades possible.

    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.

  • Ungulate - Text by M. Alan Kazlev
    General term for terragen hoofed, herbivorous, placental mammals. The hoof is made of the protein keratin. Representative baseline ungulates include horses, sheep, pigs, deer, camels, bovids, and many other species. Many ungulate species have been provolved, others have been raised to presophonce, or geneered or adapted in various ways.
