Evolutionary biology: Which came first....?

Evolutionary biology: Which came first....?



IMPORTANT: This is the 4th time I ask this. Because the answers on the other ones are all wrongly accusing me of trying to debunk evolution. Nonsense! I am not a creationist!

Now that that's aside. Which came first in all of these:

Heart or veins?

Lungs or windpipes?

Stomach or throats?

Sclera or pupils?

Earholes or eardrums?

Spine or ribs?
