- Didn't you ever learn this in biology class?
- I hate coming to the dentist, why do we even have wisdom teeth?
- Examples in humans
- ZZZZ....
- Years Prior (back in grade 11 biology)
- - Structures that were once functional, now are unnecessary- Structures or traits that no longer serve the same purpose they formerly did in a particular species.- Body parts that were used by ancestors which no longer serve a purpose
- Vestigial structures, are traits or specific body parts that now serve a different purpose than before, or render entirely useless.
- A great example of this in nature is, whales having pelvic bones that are inherited through their ancestors who used to be land mammals.
- Vestigial Structures
- Back to the present
- - The appendix- Tailbone (coccyx)- Wisdom teeth etc...
- Like whales, humans also have vestigial structures. Some examples include, the appendix, the tailbone, and also wisdom teeth.
- Wisdom teeth are probably the best example when coming to learn about vestigial structures in humans
- - Originally inherited through our great ancestors, the purpose was to help chew through rough food better- Wisdom teeth are no longer needed as they only just cause discomfort now, and modern food nowadays is cooked, meaning way easier to chew
- Our ancestors actually needed them to help them with their daily lives. Since food was often eaten raw and rarely cooked
- But now there is no purpose of having them at all, exactly like other vestigial structures in humans, and all other animals in the world
- Wisdom Teeth
- Before modern technology, our ancestors would often eat meat, leaves, nuts etc.. Which furthered the purpose of having extra molars
- NO! I always fell asleep during those classes
- Can you please just get this over and done with, I cant deal with this pain!!
- The End
