What is the body of the declaration of the independence about?

The body of the Declaration of Independence is made up of two sections.

The first section of the body of the Declaration gives evidence of the "long train of abuses and usurpations" heaped upon the colonists by King George III. The second section of the body states that the colonists had appealed in vain to their "British brethren" for a redress of their grievances. Having stated the conditions that made independence necessary and having shown that those conditions existed in British North America, the Declaration concludes that "these United Colonies are, and of Right ought to be Free and Independent States; that they are Absolved from all Allegiance to the British Crown, and that all political connection between them and the State of Great Britain, is and ought to be totally dissolved."

genetics is the study of how dna works, the methodologies defining the new recent technologies allow scientist to have a panoramic view of the entire dna landscape, especially how genomes interact with their environment, including off course, factors outside their organisms.

thus is very possible the existence of both scenarios, where populations of isolated individuals have different genetic traits, and share traits related to genetic mutation, due rats can easily travel overseas using human transport channels. so scientists could get a vast number of data, including human interaction, evolution of rodents, health development, spread of infections, development of new organisms, how genomes evolve in different environments and so on.
