Ateam of scientists is researching the relationship between the two subspecies of a. africanus and concludes that the subspecies were actually different species. which of the following would increase the reliability of this conclusion?
a. second group of scientists finding significant differences in the dna of the two different subspecies
b. providing a description of the methods used in their experiments that led to the conclusion
c. finding the two different subspecies of the species in different geographic locations
d. publishing their research in order to make their findings available to the public

The best response to this question about the subspecies of A. africanus being species and not just subspecies is Option A. A second group of scientists finding significant differences in the DNA of the two different subspecies. This would prove that the findings are repeatable and thus it increases reliability.

Explanation:

Reliability in scientific research is assured when the experiments are repeated and very similar results are achieved. Ideally, the experiment should be repeated on the DNA from different individuals in the sample of the two subspecies. Reliability is usually expressed as a percentage – if you get exactly the same results from the DNA testing every time then the test or experiment results are said to be 100% reliable.
