what are wisdom teeth for?

Question

really what are they for

Answer 1

Wisdom teeth are vestigial traits, meaning that they were useful at one time, but not any more.

Before humans had utensils and we ate raw meat and tough vegetables, the more teeth we had, the better for us.

Now that we have knives, we don't need our wisdom teeth.

Another vestigial trait is the appendix, which was used by our ancestors to sort out rocks from our food.

Answer 2

Wisdom teeth are third molars that usually appear between the ages of 18 and 20 (although they may appear when older, or fail to appear at all). They are called "wisdom teeth" because they appear so late—much later than the other teeth, at an age where people are supposedly wiser than as a child, when the other teeth erupt. Often they need to be removed when they impact against other teeth—colloquially known as "coming in sideways."

Answer 3

i just had my wisdom teeth removed.. wisdom teeth are really useless... there no purpose to them.

Why do we have wisdom teeth that are often removed?

Our third molars, commonly known as wisdom teeth, cause dental problems in modern humans because our jaws have gotten smaller since the genus Homo emerged. Space in the mouth for teeth has been reduced in part because of the development of stone tool technology and cooking.

Early humans before the invention of stone tools relied upon large, powerful jaws to chew tough foods. Later in evolution, stone tools could be used to process foods to be easier to chew. Cooking also softens foods, lessening the amount of work to be done by teeth and jaw muscles. When large jaws were no longer crucial for the success of the species, the energy used in building and maintaining those large structures could be better spent on other functions and they became smaller while the number of teeth in the jaw remained the same. This has caused problems because those teeth must fit into a smaller space than they did in the mouths of earlier humans.

Answer 4

Some people actually DO have large enough mouths (ie my husband) and they do not get removed. Very often just like they are removed, they are also kept in a person's mouth and actually *gasp* used. So therefore I have answered your question simply put, the wisdom teeth are for chewing your food.

Answer 5

Mine got impacted about the same time that my daughter started teething. I think I got them to remind me of the pain of teething.

Answer 6

They are teeth that are still in our mouths when we evolved. They do not serve any purpose. Eventually. in future generations, they might stop growing and simply evolve more.

Answer 7

They are for wisdom.
