'''Developmental biology''' is the field of [[biology]] involving the study of the development of complex [[organisms]] from a single [[cell]], the fertilized [[egg|ovum]] (called a [[zygote]]), to maturity. While developmental biology may be used to refer to the study of [[plant]] and [[fungus|fungi]] development, the most active area of research, by far, is the study of [[animal]] development. | '''Developmental biology''' is the field of [[biology]] involving the study of the development of complex [[organisms]] from a single [[cell]], the fertilized [[egg|ovum]] (called a [[zygote]]), to maturity.
