In Christian and Jewish creationism, a religious view based on the creation account of the book of Genesis, created kinds are purported to be the original forms of life as they were created by God. They are also referred to as kinds, original kinds, Genesis kinds, and baramin (a neologism coined by combining the Hebrew words "bara" and "min" [kind, though the combination does not work syntactically in actual Hebrew). The idea is promulgated by young Earth creationist organizations and preachers as a means to support their belief in the literal veracity of the Genesis creation myth as well as their contention that the ancestors of all land-based life on Earth were housed on Noah's ark before a great flood. Old Earth creationists also employ the concept, rejecting the idea of common descent. In contrast to young Earth creationists, old Earth creationists do not necessarily believe all land-based life was housed on the ark, and some accept some evolutionary change within the given kinds has occurred.
