Question
Two nucleotide sequences found in two different species are exactly the same. This suggests that these species
- Are evolving into the same species
- Contains identical DNA
- May have similar evolutionary histories
- Have the same number of mutations
The correct answer is: May have similar evolutionary histories
Comparative biochemistry shows that the more similar the DNA of two species is, the more closely related they are, and the more recently they get evolved separately

Which of the following statements are incorrect?
I. Microbial experiment shows that when the pre-existing advantagoeus mutations are selected they will result in the observation of new phenotypes. Over few generations, this would results in speciation
II. Neanderthal fossils represents a human relative.
