As a matter of biological science, biological science has disproved the age-old hypothesis of race which, we must remember, was never anything more than a hypothesis developed long before DNA was discovered. And so "race" was a hypothesis in search of proof rather than the result of an empirical search for truth. We have to remember that the hypothesis of race was born before doctors became aware of bacteria and began washing their hands before conduction surgical operations. So, it ought to be no surprise that a theory of genetics developed before genes could be seen and identified turned out to be, quite simply wrong. As the march of science progresses, we develop new tools for ever more minute analysis of human matter and these new tools have demonstrated the falsity of an old hypothesis.
That really ought not surprise anyone, since we all know that a guess as to the length and width of a piece of wood is rarely as good as measuring the wood with modern tools. And a guess as to the age of a statue is not quite as good as carbon dating. As our tools become better our knowledge increases.
Rarely, however, has a scientific discovery had so many important ramifications for the United States of America. For example, the US Constitution requires that a census be conducted every ten years. As the following citations show, the Census is an integral part of determining the representation that each state will have in the US House of Representatives, and the Fourteenth Amendment modified the Constitution to make it clear that Blacks could participate more fully in US electoral rights.
The US Constitution's Article 1, Section 2 originally provided that.
(Representatives and direct Taxes shall be apportioned among the several States which may be included within this Union, according to their respective Numbers, which shall be determined by adding to the whole Number of free Persons, including those bound to Service for a Term of Years, and excluding Indians not taxed, three fifths of all other Persons.) (The previous sentence in parentheses was modified by the 14th Amendment, section 2.) The actual Enumeration shall be made within three Years after the first Meeting of the Congress of the United States, and within every subsequent Term of ten Years, in such Manner as they shall by Law direct.The US Constitution as modified by the Fourteenth Amendment's Article I, Section 2:
2. Representatives shall be apportioned among the several States according to their respective numbers, counting the whole number of persons in each State, excluding Indians not taxed. But when the right to vote at any election for the choice of electors for President and Vice-President of the United States, Representatives in Congress, the Executive and Judicial officers of a State, or the members of the Legislature thereof, is denied to any of the male inhabitants of such State, being twenty-one years of age, and citizens of the United States, or in any way abridged, except for participation in rebellion, or other crime, the basis of representation therein shall be reduced in the proportion which the number of such male citizens shall bear to the whole number of male citizens twenty-one years of age in such State.
