Today is the 200th anniversary of both Darwin's & Lincoln's birthdays, a historical coincidence only rivaled by John Adams and Thomas Jefferson both dying on the 50th anniversary of July 4, 1776.
Unfortunately, while Lincoln's contribution of preserving the Union an abolishing slavery has caught on, Darwin's achievement is thought to be true by only 39% of Americans. Sigh. The good news is that, by age cohort, young folks are by far the most likely to believe in evolution, with over 50% 'buying' it.
It is amazing that Darwin was able to postulate evolution 100 years before anyone knew what DNA was. And it is further amazing that the widespread sequencing of many genomes over the past 10 years has provided the final proof that evolution is clearly occurring. Anyone who doubts this just a damn fool.
