The early stages of development of a plant or animal, especially a human baby before it's fully developed in the womb.
From Greek 'embryon' meaning 'young one' or 'fetus,' from 'em-' (in) and 'bryon' (to be full of life). Medical and scientific terminology adopted it for early developmental stages.
Human embryos develop all their basic organs in just the first eight weeks—it's such rapid organization that scientists still don't fully understand how genetic instructions build a body so quickly.
