History of representative democracy in USA

The correct answer to this open question is the following.

The concept of representative democracy in the United States started with the creation of the US Constitution during the Constitutional Convention in the city of Philadelphia, Pennsylvania during the summer of 1787. Delegates met to discuss the new form of government after the Articles of Confederation had left a weak central government that couldn't collect money through taxation or organizes an army.

Here, the founding fathers opted for the principle of Republicanism, in which the citizens can elect their representatives to create laws that help the nation to progress in peace.

America is a representative democracy in which its citizens are able to participate in elections to choose small groups of people to make laws and policies for them.

For that to happen, political parties choose their candidates that compete in elections.

in february 1787, congress decided that a convention should be convened to revise the articles of confederation, the nation’s first constitution. in may, 55 delegates came to philadelphia, and the constitutional convention began. debates erupted over representation in congress, over slavery, and over the new executive branch. the debates continued through four hot and muggy months. but eventually the delegates reached compromises, and on september 17, they produced the u.s. constitution, replacing the articles with the governing document that has functioned effectively for more than 200 years.

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.
