question 5(multiple choice worth 3 points) (05.03 - mc)
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 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:

To support the validity of a scientific conclusion (here, about hominids' common ancestor), independent replication by other teams arriving at the same result is key. Explaining procedures helps transparency but not direct validation. Addressing contradictory evidence defends the conclusion but doesn't prove it. Publishing in a popular magazine doesn't ensure scientific rigor. So independent teams' confirmation is best.

Answer:

A. Independent teams reviewing their work and arriving at the same conclusion
