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.

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.

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.
