- A mammal (from Latin mamma ‘breast’) is a vertebrate animal of the class Mammalia (/məˈmeɪli.ə/). Mammals are characterized by the presence of milk-producing mammary glands for feeding their young, a neocortex region of the brain, fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors diverged in the Carboniferous Period over 300 million years ago. Around 6,400 extant species of mammals have been described and divided into 29 orders.
Of how moche sorer punyshment suppose ye shall he be counted worthy which treadeth vnderfote the sonne of god: and counteth the bloude of the testament as an vnholy thynge wherwith he was sanctified and doth dishonoure to the sprete of grace.
Hebrews 10:29 TYN
