But what one should ask is whether the survival of these emperor penguins depends on natural selection, luck or something else? Say no to plagiarism.

This is a very important theory of evolution and holds true in many scenarios. Emperor penguins depend on natural selection to thrive in the Antarctic climate. There are many examples of this being true, where this is still happening. When a mother goes to look for food, the male and infant stay behind and wait for the mother to return. If it is not strong enough to make the journey and fails to return, the male will abandon the chick to get food. This ensures that the mother's weak traits are not passed on to the next generation when the chick dies. When the mother returns to feed the chick, the male goes to get food. Of course, if he cannot make the journey and dies, this prevents him from reproducing further and passing on his weak trait. When a storm approaches, only the strong chicks survive. Those unable to weather the storm are eliminated from the colony. There are examples of natural selection that has already occurred. How do penguins know where to find their breeding ground? My theory is that previous penguins tried to breed closer to the ocean and the ice wasn't strong enough to support the breeding group. Over generations, they could determine where the safest spot was (over 60 miles from the ocean), when other penguins lost their eggs, and the like if the ice broke and they fell.

Only the strongest penguins can make the journey back and forth between the water and fertile soil, and only the hardiest chicks can survive the storm. Over time, this makes penguins more hardy and resilient.
