Why are DNA sequences more similar in more closely related organisms?
In fact the organisms are closely related because the DNA sequences are more similar. DNA sequences are more different as the organism differs.
The more similar the DNA sequences of two species are the more closely related the species are?
Since all organisms have the same DNA, just different amounts and sequences, the more similar the sequences, the more closely related the organisms.
How does the variation in protein reflect changes in a species DNA?
As new species evolve they build up differences in the DNA from related species, as a result of mutation and selection. The role of DNA is to encode the structure of proteins. The DNA code defines the sequence of amino acids in each protein. So if the sequence of bases in the DNA changes, the sequence of amino acids in the proteins can also change as a result. If we compare closely related species there should be fewer differences in their DNA and so fewer differences in their proteins than between distantly related species. By comparing amino acid sequences we can therefore estimate how closely or distantly related two species are to each other. (see related links)

What kinds of evidence Indicate indicate how closely species are related?
The kinds of evidence that indicates how closely species are related are evidence of DNA and protein structure.
