How does the use of molecular data such as DNA and protein sequences compare to the use of anatomical evidence? What are the pros and cons of each type of evidence?

There are different evidences for evolution that includes anatomy, fossils, molecular biology and biogeography.

Molecular biology uses DNA and protein sequences that the genetic code reflect the shared ancestry of life. DNA comparisons used for the anatomical evidence.

All living cells are organized in the same basic DNA and use the same genetic code. Proteins derived from genes, all originate from the same set of amino acids.  Comparing parts of DNA in various species has shown that even very different organisms still have significant parts of similar DNA. For example, in chimpanzees and humans have some precent of same genetic structure. In the amino chain, chimpanzees and humans have only one position, while humans and moths have 31 different positions.

There are different advantages and disadvatages of each type of evidences are:

Advantages:

Disadvantages:

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
