... it does not mean that human embryos go through all the stages of fish embryos, just that they share stages of development with closely related organisms, the closer the relationship the more the developmental stages are shared. The more distantly related organisms diverge in development sooner.
Are you, for example contesting that human embryos have tails in their early stages?
Just a note to readers, we have actually been through this before. Another example of old arguments being renewed and acted like they were never addressed, which is why those interested would do themselves (and us) a big favour in going back and reading old posts, because it's relied upon that you won't!
At any rate, this is an evolutionary tale of a "tail". Basic biology/anatomy knows the coccyx is a very important bone in the body, as it is required for support of posture and defecation (and other things)...
Evolutionists like to find traits and fit them in with us ascending from lower animals. But is this "tale/tail" honest? Consider this:
As the baby is developing in the womb, some areas are unfolding first for good reason. The spine will indeed stick out to be much more noticeable, as it then stimulates the muscles and limbs to develop/surround/envelop. Consider all the nerves/brain/eye centres in connection with the spine. The need for first frame/foundation should be no real mystery to anybody who puts some thoughts into this and why the rest of the growth relies upon it.
After further growth of surrounding areas, the coccyx winds up inside the body. Just another example of the miracle of the developing human being.
