Yes, because vestigial structures can be harmful. For example, some humans are now born without an appendix which ensures they will not be killed via appendicitis.
Having a smaller expression of a vestigial structure, like having a smaller appendix, saves on the energy wasted in maintaining an unneeded structure.

why are structures not removed by natural selection?
Vestigial structures do not harm the organism. Nature selects against only harmful traits.
Why are vestigial structures not removed by natural section?
Vestigial structures are remnants of features that were once functional in an organism's ancestors but are no longer needed in the current environment. Natural selection does not actively remove these structures because they do not typically have a negative impact on an organism's fitness. Since they do not hinder survival or reproduction, they are not actively selected against.
A small number of finches are removed randomly from the wild and placed in a protected bird area. they need and have plenty of space. why would natural selection not occur in this population?
The population has not reached carrying compacity is correct on apex
What two structures will be ligated for a cholecystectomy?
During a cholecystectomy, the cystic duct and the cystic artery are the two structures that are typically ligated. The cystic duct connects the gallbladder to the common bile duct, while the cystic artery supplies blood to the gallbladder. Ligation of these structures ensures that the gallbladder can be safely removed without causing complications.
Within which structures in humans are bacteria and dead cells removed from lymph?
Bacteria and dead cells are removed from lymph within lymph nodes, which are small bean-shaped structures located along the lymphatic vessels. Lymph nodes contain immune cells that help filter and eliminate these harmful substances from the lymph fluid before it is returned to the blood circulation.

Why do molluscs have a soft body?
When they first appeared, they all had a hard shell to protect them, as they evolved and natural selection removed some of their relatives, this trait was removed and (like octopodes and squid) the shell became a vestigial structure and was removed.
Why wisdom teeth are vestigial structures?
They are not needed (we have enough teeth without them) and there is no room for them. Almost everyone needs to get them removed. They are more of a pain (literally) than they are worth.
What do they remove in an appendectomy?
The appendix is removed. The appendix is a vestigial organ found in the cecum. If it gets inflamed, it is removed and the surgery is called appendectomy.
What is vestigial side band transmission?
Vestigial sideband (VSB) is a type of amplitude modulation ( AM ) technique (sometimes called VSB-AM ) that encodes data by varying the amplitude of a single carrier frequency . Portions of one of the redundant sidebands are removed to form a vestigial sideband signal - so-called because a vestige of the sideband remains.
What is appurtenant structures?
Something that is attached to the structure that can be removed.
What are the main structures you could have observed when you removed the exoskeleton of the abdomen of a crayfish?
The large feathery structures are the gills.
Which is an example of vestigial structure?
Most of the "higher evolved" animals I can think of have a vestigial structure or two. The most common example given is of the vestigial leg structures that can be found in the back of whales. Ostriches can't fly so i think their wings are considered vestigial. Humans have a vestigial tail bone.
Why is the appendix known as vestigial?
Because it no longer serves any useful purpose. It can be removed, without the body suffering any deterioration from its loss.
What are the main structures you could have absorbed when you removed the exoskeleton by a crayfish of the abdomen?
the tail
