Answer:

For the answer to the question above, the genetic evidence of phylogenetic relationships proves that organisms that are different now shared common ancestors. 

The fossil record shows how organisms have evolved. 

You could use the example of how humans have significantly changed the form of many animals by selective breeding. 

There is evidence of adaptive radiation like the tortoises or finches of Galapagos. It also exists in the similarity of many species like all the different species of cats, horses, dogs

Answer:

Molecular biology. DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are.

Biogeography. The global distribution of organisms and the unique features of island species reflect evolution and geological change.

Fossils. Fossils document the existence of now-extinct past species that are related to present-day species.

Direct observation. We can directly observe small-scale evolution in organisms with short lifecycles (e.g., pesticide-resistant insects).

Identify a scenario where an experiment would be replicated
Vsevolod [243]

Answer:

If you did not follow the procedure as you should have.

Explanation:

You may have to repeat an experiment for several reasons. It can be because you need to be certain of the results so that you have to perform it several times. Or you need more precise results so that you can fine-tune the variables and repeat the experiment again.

The most common scenario where an experiment would be replicated would be in a situation where you did not follow the procedure that you have outlined exactly like you should have so that the results you got are not 100% reliable. In such a case, the experiment would need to be replicated for the correct results.

I hope this answer helps.
