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.

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.

Type your answer here... The appendix can be removed if it is infected and if it is troubling you
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.
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.

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.

If the appendix gets blocked by a bit of faecal matter (poo) then it can get inflammed and infected. It can then really easily burst into your abdominal cavity and get infected. That infection can then get into your blood, causing it to become infected. You can potentially die from it.
No, the sentry key (skim) is a learned function that can not be removed.No, the sentry key (skim) is a learned function that can not be removed.
