Developmental genes are often highly conserved. However, organisms with very similar genes can appear quite different. How is this possible?

The genes may usually undergo mutation during development, resulting in the production of varied proteins in individual cells.
If an identical gene is turned on at different stages in development, it can have very different effects.
Even if genes are quite similar, they always produce proteins with different functions.
If the genes are very similar, they must always be expressed similarly (at similar times in development) but may sometimes stil have varying effects.
