Question

A population of peppered moths is monitored over several generations. It is observed that the number of white moths compared to the number of black moths changes with each successive generation. This means that the population cannot be at equilibrium and the population is therefore evolving.

True
or
False

Answer 1

True

Step-by-step explanation:

Evolution is the change in the characteristics of a population over generations. This is caused by nature selecting out some disadvantageous traits and preserving advantageous traits over successive generations through natural selection pressures. In this case, the white moth is at a disadvantage in the environment compared to the black moth. The allele for white color is, therefore, ‘weeded out’ over time.
