The 8:00 minute video below captures the amazing abilities of a fish known as the Archerfish.
As you watch the video ask yourself how many structural and behavioral changes needed to occur in order for this fish to be able to do what it does. How many algorithmic changes had to be made in the neural wiring in the fish's brain just to enable it to adjust for the refraction of the light coming from the prey or to adjust the stream of water to adjust for distance?
Could all of the necessary mutations in the organism's genome have occurred by serendipity or does the Archerfish's incredible ability not point instead to intentional design?
Ask yourself as you watch which is a priori (that is, setting aside any prior commitment one way or another) a more plausible explanation for this phenomenal behavior, chance or intelligent engineering and programming:
