DNA code to me is basically software program that ties virtually everything together in the Matrix of this God forsaken planet, heredity factors in this software program is what separates us from apes dogs cats yadda yadda.
Each species has a unique DNA sequence when looked at as a whole (complete DNA sequence of each species is called a genome). However, scientists see relationships between each species' DNA sequence and in the shape of each species, and then they factor in the geographic distribution of these species, both in the past and current distribution. When all of these factors are brought together, DNA and how the body is built, groups of species seem to form lines of heredity that span the species level. If each species were created individually, this type of relationship shouldn't exist.
The same DNA similarities that can tie Thomas Jefferson to his slave mistress many years later through comparing descendants DNA can also tie species to species through time. The fact is DNA sequences change over time, even if the species looks the same. When changes in DNA sequences change an aspect of a species that also changes its ability to have fewer or more offspring, that mutation is selected for or against by the environment. To be a bit clearer, DNA Mutation--->Change in Fitness (ability to have more offspring)------->Selection by the Environment in favor of the mutation. Also, if two groups of a species are separated (no gene flow between the two populations) small changes in the DNA build up between the two species. Over time, these changes are incompatible with interbreeding and two new species are born. Working backwards with the DNA sequence we can detect if two species are related in this fashion.
The first clue to this branching characterstic is seen in the fossil record, where species slowly look more and more like current species as you move up the geologic column. Before DNA was even discovered, people were creating tree like diagrams that showed the relatedness of different species. When DNA sequences were found in current species, they fit the already made diagrams to a tee. Why would this happen if creation were true?

Arguably every organism has a unique DNA sequence, even within clonal populations of bacteria you are likely to find some polymorphism somewhere.
To suggest that a genome is the complete DNA sequence of a species is misleading. The Genome is the complete DNA sequence of one organism what most genome projects with the pooled donor approach are trying to do is establish a representative reference genome for the species. A good example of this difference would be the Celera Genome which is in the most part derived from Craig Venter's DNA and the HGP genome which was from a large pool of anonymous donors.

Point taken. One can talk about an organism's genome and a specie's genome. I think genome can be used correctly in each sense but the two concepts are separate. Thanks for pointing this out. Perhaps gene pool is better understood in reference to a specie's genome.

Indeed i do think that we are living on the planet of the apes. Considering the very important fossil findings the anthropologists have made so far. as far as our evolution is concerned, i do strongly belive that our ''monkey'' ancestors had once walked this planet, and that some day, we will be refered to as apes too, by those into whom we will evolve during the next 40 million years!!
