Milk is everywhere. From the dairy aisle at the grocery store to the explosive cover of the Mother’s Day issue of Time magazine , the ubiquity of milk makes it easy to take for granted. But surprisingly, milk synthesis is evolutionarily older than mammals. Milk is even older than dinosaurs. Moreover, milk contains constituents that infants don’t digest, namely oligosaccharides, which are the preferred diet of the neonate’s intestinal bacteria ( nom nom nom! )  And milk doesn’t just feed the infant, and the infant’s microbiome; the symbiotic bacteria are IN mother’s milk. Evolutionary Origins of Lactation The fossil record, unfortunately, leaves little direct evidence of the soft-tissue structures that first secreted milk. Despite this, paleontologists can scrutinize morphological features of fossils, such as the presence or absence of milk teeth ( diphyodonty ), to infer clues about the emergence of “milk.” Genome-wide surveys of the expression and function of mammary genes across dive

Last week the internet was aflutter with reports about Curtis a man who was planning to exclusively consume his wife’s breast milk. The couple had accumulated a stockpile of frozen breast milk that was no longer needed since weaning their baby. Dr. David Katz , director of the Yale Prevention Research Center, reportedly responded by saying that "the rapid growth and brain development of early childhood is best fueled by the high-fat, energy-dense elixir of breast milk." Its reported that Katz then further explained that breast milk has less value to an already developed adult. While the second half of Katz’s response is indeed supported by data, the first half demonstrated a wide-spread misconception about the specialness of human breast milk and provided the opportunity to present the first substantive post for Mammals Suck… Milk! To cut to the chase, it turns out that human milk is indeed super special! Just like the milk of each mammalian species is super special
