Lactation describes the secretion of milk from the breasts when a mother feeds her young. It occurs with almost almost all female mammals after the birth of their young. In humans the process is also called "breastfeeding" or "nursing".
In most species, milk comes out of the mother's nipples. The platypus (which is a monotreme mammal) releases milk through ducts in its abdomen. In only one species of mammal, the Dayak fruit bat, is milk production a normal male function.
Milk contains fat, lactose, and protein, as well and vitamins and minerals.
Apart from food nutrients, mothers' milk contains a range of antibodies which protect the baby until it develops its own immune system. When born, a baby has IgG antibodies from across the mother's placenta. Its own immunoglobulin production takes about six months to develop after birth, so meantime the mother's milk supplies IgA as a stop-gap protection.
Milk production requires the hormones prolactin and oxytocin.
The evolution of milk production made use of a feature which was present before modern mammals. The cells which produce milk were developed from the apocrine glands in the skin:
Meaning: since the skin of synapsids had glands in it, the development of milk production was possible.

Modulo operation
In mathematics, the modulo operation works out the remainder (what's left over) when we divide two integers (whole numbers without a fraction or a decimal) together. For example, 5 modulo 2 is 1, because if we divide 5 by 2, then we get 2 (because formula_1) with 1 left over. Instead of writing modulo, people sometimes write formula_2.
Because computers and calculators store numbers in different ways, they sometimes use different steps to work out the modulus (what we get when we modulo two numbers).
