What do you call body parts we evolve from having any use?

Vestigial structures are anatomical structures of organisms in a species which are considered to have lost much or all of their original function through evolution. These structures are typically in a degenerate, atrophied, or rudimentary condition or form. Vestigial structures are often referred to as vestigial organs, though not all of them are actually organs.\n\nAlthough the structures most commonly referred to as "vestigial" tend to be largely or entirely functionless, a vestigial structure need not necessarily be without use or function for the organism. Vestigial structures have lost their original main purpose, but they may retain lesser functionalities, or develop entirely new ones.[1] Thus, a "vestigial wing" need only be useless for flight to be vestigial; it may still serve some other purpose than that of a wing.

Humans are designed to evolve; spiritualy, mentaly, and physicaly. Evolution takes place every generation and we are growing at a rapid rate.\nHere's an annalogy, a different type of being see's an infant human, and an infant hippo next to each other. The hippo can walk and defend itself right after birth, where as the infant human can do nothing but sit, cry, and roll around. It's obvious which would be "smarter" in the current state. Looking outside the "box of time" the human will grow to be smarted than a hippo in many ways when it reaches maturity because it evolves with time... hope i could help you feel better about everything, i feel like you've had a hard time lately... things will get better, just remember that.

Common ancestor.  It's like having five fingers--it's not necessarily the ultimately best number of fingers to have, but the bone arrangement has been around since we got it from the actinopteryginii and possibly even before.  We just happened to get it from the animal that happened to make it.  Evolution can work in favor of dumb luck, occasionally.

Yes...it really has no other "use" other than to produce pleasurable sensations and orgasms. Technically speaking, it is the female equivalent of the penis (it develops from tissues in the same area, and has a similar structure)... and since we all start out life as heading towards female if there isn't a "Y" chromosome around to say "male", really the penis is just an outsized clitoris that happens to have some plumbing running through it.

Homologous parts is about comparing *two* species (or male and female from the same species).\n\nTherefore only #2 is an example of homologous parts (as it is a comparison between dogs and humans).\n#1, 3, and 4 are examples of vestigial organs (or more correctly, 'vestigial structures' ... as sometimes the thing is so useless that it can't be called an 'organ' ... like the python leg bones).\n\nBy the way, some people might question whether human ear muscles are truly vestigial, because they are operational in some people (I can wiggle my ears).  However even if they work, it's hard to find a *purpose* for them, as is needed in other species to move ears for better hearing.  Similarly, some people claim that the human appendix sometimes serves some function for fighting infection.  However, the tailbone has no apparent function ... it's just a throwback to our embryology and ancestry.

The 'modern' human experiment could be seen as an answer to your question.  We now, for our 'comfort' do things which are certainly to be considered 'adaptive selection of species'.  The way this results in 'natural selection of a population' can be felt and seen and even quantified, if one is sentient and humble enough.  Glad to help!

In biology and ecology, an organism (in Greek organon = instrument) is a living complex adaptive system of organs that influence each other in such a way that they function as a more or less stable whole.

That would be an exoskeleton. Basically a shell on an organism (ants, beetles, most insects), instead of having bone structures such as humans and other mammals

Adaptation? Evolution?

it depends on what you consider a body part... just bones?  bones and muscles?  And tendons... ligaments....

It's difficult to use vestigial organs as proof for evolution for two reasons.  1) You have to prove that a vestigial organ is, in fact, the remnant of some ancient organ, particularly an organ for which organisms would no longer have a need.  This is virtually impossible to do, as we have little information regarding the anatomy and physiology of prehistoric organisms. 2) You also have to prove that the vestigial organ is, in fact, a vestigial organ.  There are other examples of organs or appendages that were originally considered to be 'vestigial' and were then later found to have useful functions.  For example, the Vermiform appendix was originally considered to be a vestigial organ in mammals, but many scientists have shown that it may actually have a physiological role.  It's quite possible that all vestigial organs may have a role that we simply haven't discovered yet.  Many biologists have suggested that a vestigial organ be redefined as an organ that we simply don't understand.

There is a tailbone in humans which is redundant, just like an appendix. Appendix has use for animals in digesting raw food. People stopped eating raw food, making it redundant. \nIf you check the ancient drawings, ancient humans had a lot of body hair, but as humans evovled, the hair became less.\n\nTo the person above - Neanderthal, Cro-magnan, Homo-erectus fossils are what you can call a "Transitional" fossil to prove evolution.\n\nTo the person who asked the question - Mutation, adaptation and evolution are inter-linked. Monkeys did not evolve into humans overnight. Or it wasnt a case that monkeys gave birth to humans suddenly. Adaptations and mutation over generations results into evolution. In fact you can say that Mutation and adaptations are preliminary steps of evolution.\n\nTo hutsong - Evolution is how life evolved from primitive life form into the current species. It, in no way speaks how life was created in the first way.\nAlso you talk about experiments in labs have proved that one life-form can not evolve into a different life-form. Heres a  question for you - How many years are these laboratories set up for? If the answer is less than 500 years, then its not enough time frame for any evolution to be seen.\nAlso you are giving links to a website which can is run by christains who are staunch opponnents of evolution not scientifically but religiously. So that has no weight at all. Maybe links to magazines like Science or Nature would have been more convincing.\n\nThumbs up to emilyrose!!

Your body adapts to the change.

The word  evolution means to evolve to change. So if we  came from apes how come we still have apes, after all if man went with an ape the ape population would no longer be around, I've never heard of such utter rubbish in my life, we were created by a power beyond our understanding, just look around you, what do you see, take a seed, how does it grow into a tree etc etc. It only takes a bit of common sense.\n\nGloria(BSYA)

Yes, but there would have to be other anatomical changes to take advantage of it, like having torso horizontally alligned. Human bipedal locomotion is a relatively recent development that had to start with a limb system adapted more for climbing trees. Birds and their ancestors (bipedal therapod dinosaurs) have been running around for hundreds of millions of years and have evolved a much better anatomy for it. Their knees bend backwards relative to ours (see ref). Birds that do not depend on flight to escape (like ostriches and road runners) can really book.
