These visible examples show the question style. LearnClash turns the full topic into ranked duels and spaced repetition.

  1. 1 Easy

    Answer: Mitochondria

    Why: Like the bacteria they came from, mitochondria still carry their own small loop of DNA.

  3. 3 Hard

    What new food did lab E. coli evolve to use after 30,000 generations?

    Answer: Citrate

    Why: Only 1 of the 12 parallel populations managed it, and only after earlier mutations had paved the way.

  4. 4 Easy

    What does the selecting in natural selection?

    Answer: The environment

  5. 5 Medium

    What must offspring be for parents to count as one species?

    Answer: Fertile

    Why: Horses and donkeys can breed, but their mules are almost always sterile, so they stay two species.

  6. 6 Hard

    In which big cat do unrelated animals accept each other's skin grafts?

    Answer: Cheetah

    Why: Cheetahs probably went through a severe population crash about 10,000 to 12,000 years ago, leaving very little genetic variety.
