Some discriminators don’t get us very far in deciding which is the better explanation between blind evolution and intelligent design.
Spiders are another of nature’s master engineers. About half of known spider species (order Araneae) construct webs made of silk.
How can a trigonometric mathematical computation be programmed into the brain of an ant through a neo-Darwinian process of genetic mutation and natural selection?
It typically takes up to three generations of butterflies to make the complete journey. This means that the navigation information is genetically programmed.
While these theories may appear reasonable, given the complexity of the behavior it is unclear how a Darwinian process can be a plausible explanation.
