weeeeeb [17]

Answer:

J. W. Tutt suggested that peppered moths were an example of natural selection.

Explanation: Before industrial revolution, the population of white peppered moth is high as compared to dark peppered moth because white peppered moth can't be seen at night by the birds. After industrial revolution, sooth is spread on the surface of the trees which make easy for the bird to see white peppered moth and feeds on them. Population of white peppered moth decreases while the population of dark peppered moth increased because they cannot be seen in the dark due to black color of sooth.

So if the trees are present there they will keep the soil firm and stop it from sliding. Therefore the erosion can probably occur in the land where there are no trees.
