A scientist makes a claim that two hominid species have a common evolutionary ancestor. What 3 processes must happen to ensure this claim can be considered valid?

The correct answer is option D, that is, scientific evidence must be found, verified, and accepted by the scientific community.

A scientific claim is one, which totally relies on systematic observation and proof. It is created to be far more reliable than any other kind of claim one could make. However, unfortunately, not every scientific claim is not true. Some of the findings are precise and reliable, while others exhibit flaws.

There is a difficulty in finding out the difference between them. Although to consider the claim put forward valid, there is a need to find out the scientific evidence, then verification has to be done, and then finally it has to get accepted by the scientific community.

Answer D. Without peer verification, a claim isn't going anywhere.
