Here are some interesting video clips of animal instincts. As you ponder these complexities, consider the impossibility of evolutionary mechanisms (random mutations and natural selection) to explain their existence.

The instinctive behavior of the Australian lyrebird cannot be explained through evolution.
Richard Dawkins explains that instincts are acquired through a mechanism that has been proven to be impossible; The hard-wiring of a genetic code through acquired behavior from parents.
