Question

Based on fossilized evidence, there are scientific claims made about the evolution of certain species. If a scientist studying the fossils of a specific species had a hypothesis other than what was currently accepted, what steps should be taken to have the alternative hypothesis considered?
a. The scientist should publish the alternative hypothesis in a popular magazine to gain public support.
b. If an alternative hypothesis sounds plausible, it could be used in place of the original hypothesis.
c. It is useful to test alternative hypotheses and know that they are incorrect.

Answer 1

d. Since the original hypothesis is untestable given the circumstances, another one is more likely to be correct.

Answer 2

Are you guessing D?

Answer 3

no that is another choice

Answer 4

Which do you think it is?

Answer 5

i think is b

Answer 6

In the long term, that might happen.

But first I think the alternative hypothesis needs to be tested. Scientists are very conservative about theories: a new hypothesis is deemed 'incorrect' until it has been thoroughly tested and demonstrated to be better than the old one.

So I think the answer is probably C.

Make sense?

Answer 7

yea so first test it then if not make another hypothesis?

Answer 8

First test it.

If it doesn't pass the test - that is, if the data is not sufficient to reject the established hypothesis - then keep the old hypothesis. If it does pass the test, reject the established hypothesis in favor of the alternative hypothesis.

Answer 9

I understand, thanks
