What would explain this observation?
- A theory can unite observations before every underlying mechanism is known. Darwin’s account of selection developed from years of evidence and discussion.
- Start with a prediction. State the quantities or features you would compare, then decide what evidence could distinguish two explanations.
Build the model
- Darwin drew on observations during a round-the-world voyage, later experiments, discussions and developing knowledge of geology and fossils. His account linked variation within a species to better survival and breeding by individuals suited to their environment. Their inherited characteristics could become more common in later generations. He published On the Origin of Species in 1859.
- acquired characteristic 后天获得的性状: A feature developed during an organism’s lifetime rather than inherited as a genetic variant; scientific theory 科学理论: An explanatory account supported and tested using evidence.

다윈은 형질이 어떻게 유전되는지 '어떻게' 설명하지 못했습니다 - 유전학은 나중에 등장했음 - 그리고 이 간격이 수용이 서서히 이루어진 이유 중 하나였습니다. 그는 DNA를 몰랐으며,数十年积累了大量证据。

정의를 사용하여 유사한 양과 과정을 구분하시오.
Choose evidence that can test it
- Acceptance was gradual. The ideas challenged widespread beliefs about separate creation, available evidence was initially insufficient to convince many scientists, and the inheritance mechanism was not yet understood. Lamarck’s explanation relied mainly on changes acquired during an organism’s lifetime being inherited; this is not how inheritance operates in the vast majority of the specified examples. A study of creationism is not required.
- Compare two fictional explanations of a population changing: one says individuals developed a feature by use and passed it on; the other says inherited variants differed in reproductive success. Identify the mechanism rather than choosing by the scientist’s name alone. Place publication and later inheritance evidence on a timeline.

조건과 가정을 명시하면 다른 사람이 정확히 작업을 재현할 수 있으며, 근거 증거를 기록하면 결론을 검증할 수 있습니다. 반대되는 결과를 숨기는 것은 잘못된 결론을 반박할 수 있는 증거를 제거하는 것이며, 한 번의 측정으로는 더 넓은 주장을 입증할 수 없습니다.
Work from known quantities
- State the known values and their units. Choose the relation because its assumptions fit this case, then rearrange before substitution.
- Known: a classroom timeline marks 1859 publication and a supplied later evidence date of 1909. Interval = 1909−1859 = 50 years. The arithmetic illustrates the stated interval; it does not claim that one discovery on one day resolved every inheritance question.
A supplied historical comparison uses dates 1859 and 1909. Find the interval. Use the same sequence: known quantities → model → relation → substitution → unit and interpretation.

Check the conclusion and its limits
- Darwin did not know the modern molecular DNA mechanism. Missing that mechanism at publication does not erase later supporting evidence. Do not describe natural selection as organisms deliberately improving themselves or treat a historical controversy as current scientific uncertainty about every aspect of evolution.
- Return to the original observation. Explain what the result supports, which conditions it assumes, and one way to test a competing explanation.
Darwin explained selection using the modern structure of DNA. This claim is false: DNA's structure was discovered in 1953, almost a century after Darwin's publication. Darwin argued from variation, selection and inheritance without any molecular mechanism.
Darwin’s explanation and why acceptance took time: Acceptance was gradual. The ideas challenged widespread beliefs about separate creation, available evidence was initially insufficient to convince many scientists, and the inheritance mechanism was not yet understood. Lamarck’s explanation relied mainly on changes acquired during an organism’s lifetime being inherited; this is not how inheritance operates in the vast majority of the specified examples. A study of creationism is not required.

DNA의 구조가 발견된 시기는 다윈의 논문 출판으로부터 거의 한 세기 뒤인 1953년입니다. 다윈은 변이, 선택 및 유전을 근거로 논리했지만, 분자 기전은 전혀 고려하지 않았습니다.
유전적 변이로서 유전되는 것이 아니라 개체의 생애 동안 형성된 특징: 기술 용어를 쓰십시오.

적용된 특성(acquired characteristic)은 개체의 생애 동안 형성된 특징이며, 유전적 변이로서 유전되지 않는 것을 의미합니다.
