Extinction or Evolution

Every species experienced a hard period. Only small number of mutated animals could survive, and they became new species, replacing the old ones. Other species died out, becoming extinct species.

 The difference between extinct species and evolving species is variation; the evolving species changed and adapted themselves to the hard environment, but most extinct species never change.

However, not all variation is good for animals; some variation will make animals weaker. In the history of evolution, many mutated species also die out. Although variation is dangerous, it is the only way to survive from some hard period, such as ice age.  

Although we do not need to care about evolution, we still can learn a lesson from extinction and evolvement. Today, many people do not want change the situation they are familiar with; though they feel bored about the invariable life, they think they are safe in the familiar situation even the situation gets worse. However, profits always stay with risks. People, who are brave to make changes or even to lose their wealth, have more chances to earn more money. It is good for people care less about their wealth, when they have already cannot give up their wealth. Letting the wealth become the obstacle on development is not a right choice.

Making a change is not an easy thing; people do not want to give up what they already have and are afraid of what they might lose. Therefore, we need to force ourselves to get the courage of sacrificing our comfortable situation. Otherwise, we can never get advancement.
