Windarr- I can see that your point of view tends toward creationist and/or intelligent design. Your argument about when the notocord/spinal cord developed (spontaneously?) is flawed in that we have yet to find fossils of every living thing out there- partly because of the delicate fossilization process and partly because the search area is so vast and there are so many parts unavailable to search. Of course you can come up with arguments to dispute the above...however, it is much more difficult to answer the following questions:
1.) Why is it that all living things (and even virus particles) are based on DNA/RNA Adenine, cytosine, guanine, thymine, and uracil? Why is the main "coinage" system of ALL cells ATP?
2.) Why is there such a conservation of amino acid sequences in key enzymes that breakdown glucose? For that matter, why is the usage of glucose so universal? ... and for those cells with mitochondria- why is there such a conservation of amino acid sequences in electron transport molecules embedded in the cristae of mitochondria- like Cytochrome C? Why is oxygen the last electron acceptor of ALL mitochondria? Why not some other periodic element?
3.) How do you explain the universality of HOX genes?
4.) How come bone structure in a chimp and man are so similar? For that matter, how come the same cells (osteoclasts and osteoblasts) are used to reorganize bone in man and FISH?
I could go on and on... but these questions cannot simply be discarded as - well God made them that way- in his/her infinite wisdom. Sorrry I cannot live with such shallow answers.
