How do protostomes and deuterostomes differ in the timing of important developmental events?
What will be an ideal response?
Many protostomes undergo determinant cleavage while many deuterstomes undergo indeterminate
cleavage. Therefore, in protostomes the fate of each cell’s developmental fate is determined when the
cell is produced and in deuterostomes the fate of each cell is determined later in development.
