How does one go about testing a hypothesis? make a prediction that would (likely) occur if the hypothesis were true see if it agrees with what you preferred to be true reject the hypothesis if it disagrees with other research in the scientific literature?

The answer is make a prediction that would (likely) occur if the hypothesis were true see if it agrees with what you preferred to be true. Hypothesis is occasionally referred to as an educated guess based on expectations of an experimental research. Hypothesis can be proved (adopted) or disproved (rejected) by the result data after the research.

explanation:

the fossil record extends back to a dog-like ancestor some 55 million years ago, which gave rise to the first horse-like species 55 to 42 million years ago in the genus eohippus.
