The vessels that are going through the ocean waters are both very useful and damaging in the same time, depending on the perspective. From one side, lot of people use them as a mean of traveling from one side to the other side of the ocean, millions of people enjoy going on vacation on the ocean/sea cruises, and also millions of people are employed and make a living from those vessels. On the other hand, all of the sewage from those millions of people is released into the ocean waters, thus causing pollution of the waters, which effects the marine life and its well-being.

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
