Which of the following happens first in vertebrate development?
A) development of the neural plate
B) development of the neural crest
C) development of the neural tube
D) development of the notochord

Development of the notochord is the first event in vertebrate development, which then signals the formation of the neural plate. The neural plate then forms the neural tube, and from the neural tube, the neural crest cells are formed.
