The question, ‘Do any vestigial organs exist in humans?’ (or any other life form for that matter), first requires a definition of ‘vestigial’. But it does help regulate our biological clocks. However, the analogous organ in many other species does have an obvious function. The evolutionist compares the rabbit appendix, which is a digestive organ, to the human appendix, then states that since the human appendix does not function like that in the rabbit, then ours is vestigial! Darwin noted that humans were occasionally born with tails, and he saw these as vestigial body parts popping back up from humanity’s less-evolved genetic history. The coccyx, or tailbone, sits at the end of your vertebra and is a remnant of our ancestral … The physicians were able to trace the child’s diarrhoea and continual running nose to lack of the thymus. In earlier days, perhaps partly due to the influence of evolutionary thinking, the thymus was treated with X-ray in some children with respiratory distress.

They answer the question “Is the Appendix Vestigial… The only reason we extract them is because genetic entropy has caused us to often not have enough physical room for them--and this is a good reason to remove them. The vestigial organ conundrum also serves as an answer to those who claim that evolution has predictive power. Basically, these organs are simply there – hanging out in the body, and could actually cause problems for human health, without offering any benefits. A FREE downloadable study guide is available from creation.com/tga. Wouldn’t it be reasonable to predict that evolution works by creating new genes, organs & function that enables survival advantage over rival alleles and therefore losing functions would be the opposite, i.e. The second vestigial organ on the New Scientist list of vestigial organs is goosebumps. If the arrector pili are activated, hair that comes out of the nearby follicles stands up, giving us those famous goosebumps on our skin. Infection and pain can ensue.

And it does not represent the cleverly designed third eyelid of the bird which prevents the bird’s eyes from drying out during flight. Other Vestigial Organs.

Later versions of Wiedersheim's list were expanded to as many as 180 human "vestigial organs". The standard evolutionist response this argument (which I must have heard a dozen times, including from university professors) is to say that the functions of these organs have merely changed from what they used to be, and that 'vestigial' has never meant 'useless'. Perhaps the most well-known of the supposed vestigial organs is the human appendix. The organ is covered by the skull, so it is certainly no eye.

Around the sixth week of gestation, six swellings of tissue called the hillocks of Hiss … The human umbilical vesicle (‘yolk sac’) and pronephros—Are they vestigial? To postulate that the human pineal is therefore a vestige serving no biologic purpose is erroneous. But how does evolution works on changing these organs from functional to non-functionals? Humans also have vestigial features, evidence of our own evolutionary history. (4) The appendix is vestigial for humans, it does not perform any function but in ruminant animals, it is concerned with digestion.
