Dafna11 [192]

Creationists criticize the idea of natural selection as a circular argument, or tautology, claiming "the fittest are those that survive, and survival is how fitness is defined. "

The definition of natural selection is not tautological because natural selection is measured by contribution to the next generation, not simply survival of an individual organism.

Tautologies or circular arguments are true at all times and therefore are not productive as theories since they cannot be disproved. A tautology is a statement which is true by necessity.

Natural selection is the prevalent theory which explains biological change by predicting the mechanism behind evolution.

Nevertheless, natural selection can be explained non-tautologically. It should be described as the theory which tries to speculate as well as retrodict evolutionary change by environmental forces affecting the organisms.

Consider the hypothesis below and answer the question that follows.
OverLord2011 [107]
<h2>Answer:</h2>

The correct answer is the option C.

Which is we add equal amount of salt in all the water samples.

<h3>Explanation:</h3>
  • As in experiment we have to indicate that the boiling point of water increases with the addition of salt.
  • Now we also know that water contains many salts as compared to the distilled water.
  • So the boiling points of simple water and distilled water would be bit different.
  • So we cannot choose one for our experiment. Instead we use all water samples of equal volume adding equal amount of salt in all samples.
  • Then we will compare results for a net answer/result of experiment.
