Information: - A mammary gland is an exocrine gland in mammals that produces milk to feed young offspring. Mammals get their name from the word "mammary". The mammary glands are arranged in organs such as the breasts in primates (for example, humans and chimpanzees), the udder in ruminants (for example, cows, goats, and deer), and the dugs of other animals (for example, dogs and cats). Lactorrhea, the occasional production of milk by the glands, can occur in any mammal, but in most mammals lactation, the production of enough milk for nursing, occurs only in phenotypic females who have gestated in recent months or years. It is directed by hormonal guidance from sex steroids. In a few mammalian species, male lactation can occur. - A primate is a mammal of the order Primates (Latin: "prime, first rank"). In taxonomy, primates include two distinct lineages, strepsirrhines and haplorhines. Primates arose from ancestors that lived in the trees of tropical forests; many primate characteristics represent adaptations to life in this challenging three-dimensional environment. Most primate species remain at least partly arboreal. - Milk is a pale liquid produced by the mammary glands of mammals. It is the primary source of nutrition for infant mammals (including humans who breastfeed) before they are able to digest other types of food. Early-lactation milk contains colostrum, which carries the mother's antibodies to its young and can reduce the risk of many diseases. It contains many other nutrients including protein and lactose. - Homo is the genus that comprises the species "Homo sapiens", which includes modern humans, as well as several extinct species classified as ancestral to or closely related to modern humans, most notably "Homo erectus". The genus is between 2 and 3 million years old, taken to emerge with the appearance of "Homo habilis". It is derived from the genus "Australopithecus", which itself had previously split from the lineage of "Pan", the chimpanzees. Taxonomically, "Homo" is the only genus assigned to the subtribe Hominina which, with the subtribes Australopithecina and Panina, comprise the tribe Hominini (see evolutionary tree below). All species of the genus "Homo" plus those species of the australopithecines that arose "after" the split from "Pan" are called hominins. - Breast milk is the milk produced by the breasts ( or mammary glands ) of a human female for her infant offspring . Milk is the primary source of nutrition for newborns before they are able to eat and digest other foods ; older infants and toddlers may continue to be breastfed , either exclusively or in combination with other foods from around six months of age when solid foods may be introduced . - Modern humans ("Homo sapiens", primarily ssp. "Homo sapiens sapiens") are the only extant members of Hominina tribe (or human tribe), a branch of the tribe Hominini belonging to the family of great apes. They are characterized by erect posture and bipedal locomotion; manual dexterity and increased tool use, compared to other animals; and a general trend toward larger, more complex brains and societies. - The breast is one of two prominences located on the upper ventral region of the torso of female primates. In females, it serves as the mammary gland, which produces and secretes milk and feeds infants. Both females and males develop breasts from the same embryological tissues. At puberty, estrogens, in conjunction with growth hormone, cause breast development. Males do not develop pronounced or physiologically matured breasts because their bodies produce lower levels of estrogens and higher levels of androgens, namely testosterone, which suppress the effects of estrogens in developing breast tissue. The breasts of females are typically far more prominent than those of males. Given the information, choose the subject and object entities that have the relation of 'natural product of taxon'.
