The caterpillars of the butterfly of the turnip whitewash have a light green color and are invisible against the background
The caterpillars of the butterfly of the turnip whitewash have a light green color and are invisible against the background of cruciferous leaves. Explain, on the basis of evolutionary theory, the appearance of a protective coloration in this insect.
1) Cruciferous leaves have a light green color.
2) The material for selection is hereditary variability accumulated in populations. Butterfly white butterfly populations have adapted to changing external conditions due to the accumulation of mutations of light green color.
3) In the process of natural selection, insectivorous birds destroy caterpillars of a different color, therefore green ones are selected. His descendants who inherit this coloration will be more numerous. Their share in the population will become larger.
Thus, due to the interaction of the driving factors of evolution (hereditary variation and natural selection), a light green masking color appeared in the caterpillars.
