present and sufficient

in logic and mathematics, necessity and sufficiency are terms used to describe a conditional or implicational relationship between two statements

Present and sufficient refers to circumstances whereby some part or aspect of a complex phenomena, like humans, is accountable in terms of some (obvious or non-obvious) part or aspect of a less complex phenomena, say simpler animals, or even fundamental concerns of biology, chemistry, or physics.
