True/False. A fundamental element of science that is needed to evaluate evolution?

True/False question.





A fundamental element of science that is needed to evaluate evolution is repeatable, testable and measurable evidence?True/False. A fundamental element of science that is needed to evaluate evolution?
One can apply these standards to evolution quite simply. While evolution is not repeatable, the examination of physical evidence can be quite repeatable. For example, one can repeat the sequencing of genomes or repeat the examination of other evidence that support evolution. The measure of the age of the universe and the earth can be repeated. The geological evidence can be repeatedly examined. Of course, most scientists add new evidence rather than repeating good experiments.True/False. A fundamental element of science that is needed to evaluate evolution?
Good answer. The important point ... it is not the phenomenon *itself* that needs to be repeatable, but the *evidence* and *observations* that support it.





(E.g. the birth of a star is not ';repeatable'; ... but that does not the study of the birth of a star non-scientific.)

While I agree with the other poster, I have to draw a distinction. You can't apply these to evolution itself, but you can apply this to the evidence for evolution. As more fossils are uncovered, as more specie's DNA is tested, the trends that have been found are tested, measured, and found to have repeated themselves again and again. Evolution itself is difficult to test in such a manner -- but the historical evidence for evolution can be evaluated in such a manner. So I would say that this is True, but your teacher will probably want to hear the answer is False.





It's the equivalent of studying gravity by watching videos of people falling over and over again, instead of actually jumping up and down to check.
Evolution by it's nature is neither repeatable, testable or measureable (in a definable way). It can be examined in the biological examination of variations within populations of animals or species or fossils but given the rules of the scientific method then evolution does not fit.
