CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -Many people who develop them find that they do not have enough space in their oral cavity to accommodate a third set of molars. In modern times, wisdom teeth have become largely regarded as being vestigial structures (unnecessary parts of the human body, like the appendix).

Detailed explanation-2: -Wisdom teeth are vestigial (unnecessary) features of our bodies. Wisdom teeth removal has become a rite of passage for many teens and young adults around the globe. But if your wisdom teeth erupt in alignment with your other teeth and don’t cause any problems, you may not need to do anything.

Detailed explanation-3: -In humans, the appendix is a good example of a vestigial organ. This non-functioning organ eventually degenerates, shrinking in size and disappearing ultimately.

Detailed explanation-4: -A vestigial structure is a biological structure that has lost a major ancestral function and is usually drastically reduced in size. Well-known examples include the eyes of blind cave fishes and blind cave salamanders, and the diminutive wings of kiwis and emus.

Detailed explanation-5: -These unused structures without function are called vestigial structures. Other examples of vestigial structures are wings (which may have other functions) on flightless birds like the ostrich, leaves on some cacti, traces of pelvic bones in whales, and the sightless eyes of cave animals.
