a. Humans who appear dissimilar in terms of size, colour, and appearance belong to the same species.
 
b. Reproductive isolation is a feature that distinguishes one species from another.
 
c. Humans who appear to be so similar in size, colour, and appearance are said to belong to the same species because their DNA sequences are dissimilar and not related through a common ancestor. They are unable to reproduce themselves.
