Answer:

Genetic drift

Explanation:

Genetic drift is the process which leads to the drift or shift of the evolving genes from one direction to another and directly affects the evolution.

The genetic drift changes the gene pool of the population is a short period of time due to a sudden event which is not controlled by nature therefore the process is considered a random process.

Since the natural event suddenly changes the gene pool, therefore, the event must act on the small population as the large population cannot be affected by the same natural event at the same time.

Thus, genetic drift takes place in the small population and thus genetic drift is the correct answer.

drift in the gene pool occur due to sudden events therefore the process must take place in tyhe

Answer:

genetic drift

Explanation:

Genetic drift is an evolutionary force that requires the presence of a small population. It is a random process that fixes one or other alleles randomly in the gene pool of a population. Genetic drift does not take account of survival fitness imparted by alleles to the individuals. Since random and chance events such as the death of all the individuals having a certain allele in a population affect the small population more intensely, genetic drift works on small populations only.

Do research about new hypothesis that has replaced an older explanation of something in the natural world
Gre4nikov [31]
I believe that what is meant with the phrase "older explanation" is none other that superstition. Therefore, I will give you one superstitious belief which is now explained by science.

In Southeast Asia, people used to believe that St. Elmo's fire appears in remote areas because a bloody battle occured in that place leaving disembodied souls of the dead wandering there in the night and even in sunshine!

For generations, many people believed that this is a fact and some even say that these apparitions are diabolical or demonic in nature. So often, caution is advised to people whenever a ball of fire appears out in the open. 

However, recent breakthroughs in the 21st century helped scientists to explain this mysterious phenomena. They found out that St. Elmo's fire is actually plasma, nothing special. Now, plasma is considered one of the states of matter! But mind you, it still does not explain why St. Elmo's fire seems to have a mind of its own!
