The mothership asks
If you could shake the public and make them understand one scientific idea, what would it be?
I answer …
“There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved” (Charles Darwin, 1859)
A simple testable idea, but a powerful one, and one that can fruitfully both explain and predict phenomena. Irrespective of putative mechanism, and natural selection is just one, organisms are connected by common ancestry and continue to evolve.
