C. Publish experimental results only if they agree with current theories or public opinion.
D. Continue the procedure of an experiment or investigation under all circumstances.
B. Analyze data that was truly observed, and not data that was expected or desired.
Explanation:
In the scientific method, scientists or researchers are expected to make fair assessments and analysis of data. This prevents, what we call bias. When making conclusions, scientists need to analyze the data as they are and what was observed even if it does not agree or come out the way they expected it. If one will manipulate the results just to justify their own reasoning, the results cannot be regarded as facts.
All organisms share one common ancestor in the beginning of life. Different species have branched at different times from common ancestors hence he evolutionary tree looks like tree called a cladogram. The nodes represent the common ancestry while branches depict divergence. Therefore even fruit flies and the fruit bats even though they do not belong to the same species shared a common ancestor at one time in history.
