The logic is laughable, and here's a funny example. Evolutionists are now concluding that laughter evolved in a common ancestor of the great apes and humans. And how do they figure this? First, they tickled 22 apes and three humans (your tax dollars at work). Then they discovered similarities. As the BBC reports:
Because the sounds of the most closely related apes matched most closely in the analysis of the laughter, the researchers believe the work is proof of laughter's shared evolutionary origin, followed by adaptation to its form in the species we see today.
Should we laugh or cry?
