Текст Раскадровки

  • 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
