Question

Which of the following statements proves that new discoveries can change the current understanding of scientific knowledge? Ötzi the Iceman changed the scientific idea of how matter are fossilized. Ötzi the Iceman gave information about the effect of ice on decomposed matter. The hadrosaur in North Dakota proved that information in fossils are unreliable. The hadrosaur, nicknamed Dakota, provided evidence about the correct dimensions of the hadrosaur.

Answer 1

The hadrosaur, nicknamed Dakota, provided evidence about the correct dimensions of the hadrosaur.

Answer 2

New discoveries can change scientific knowledge and this was shown when The hadrosaur, nicknamed Dakota, provided evidence about the correct dimensions of the hadrosaur.

Science is constantly evolving and a key reason for this is that while there is a lot of scientific theory about various topics, there isn't always hard evidence to prove it.

In the case of the hadrosaur, the discovery of the Dakota fossil:

• showed that scientists had not estimated the weight of their tails effectively as it was heavier than thought
• showed that the hadrosaurs were longer than previously thought
• allowed scientists to study skin samples as well because some skin had been fossilized

In conclusion, it isn't that science it wrong, it simply made conclusions based on the available data and when new data presents better evidence, scientific theory improves.
