Question

a group of scientists studying the dna of two hominids concludes the hominids have a common evolutionary ancestor. which of the following would best support the validity of their conclusion?

independent teams reviewing their work and arriving at the same conclusion
explaining their experimental procedures in detail
proposing explanations for evidence that contradicts their conclusion
publication of their research in a popular magazine

Explanation:

Analyze the question prompt

The question asks what would best support the validity of a scientific conclusion regarding hominid DNA and evolutionary ancestry.

Evaluate the options based on scientific methodology

• Independent teams reviewing their work and arriving at the same conclusion: This represents replication and peer review, which are fundamental to establishing scientific validity.
• Explaining their experimental procedures in detail: While necessary for transparency, explanation alone does not validate the conclusion without independent verification.
• Proposing explanations for evidence that contradicts their conclusion: This addresses anomalies but does not directly validate the primary conclusion as strongly as independent replication.
• Publication of their research in a popular magazine: Popular magazines are not peer-reviewed scientific journals and do not establish scientific validity.

Determine the best option

Independent replication and peer review by separate teams is the strongest support for the validity of a scientific claim.

Answer:

• Independent teams reviewing their work and arriving at the same conclusion (Correct answer)
• Explaining their experimental procedures in detail
• Proposing explanations for evidence that contradicts their conclusion
• Publication of their research in a popular magazine
