No matter where we look in nature and no matter whether we look at whole organisms or at any system or part of an organism, down to the tiniest cells that make it up, we see evidence of intentional design.
The following short video gives us a glimpse into just a few aspects of the design that permits the Emperor penguin to survive and thrive in the harsh conditions in Antarctica. It's fascinating:
The Darwinian naturalist would have us believe that every single adaptation, whether structural or behavioral, in every single organism on earth, came about because of some fortuitous genetic mutation which was then seized upon by natural selection and promulgated throughout the population.
For the naturalist genetic mutation is a magic wand that has blindly and solely by random chance produced the trillions of adaptations we find in living things.
The faith it takes to believe in the efficacy of mindless, unguided processes in nature is truly impressive.
