Explain, from the point of view of the laws of evolution, the appearance of a dissecting coloration in striped butterfly fish.

1) mutations occurred in the original population, leading to the appearance of a color that divides the contour of the animal;
2) the dissecting coloring made the animal invisible against the background of the environment and increased the chance of survival in the struggle for existence;
3) as a result of natural selection, the mutation is fixed, spread due to reproduction in the population, which led to a change in its gene pool.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
