With the passing of stringent laws and pollution control measures in Britain, there has been a decline in the frequency of melanic form of the Peppered moth. The most likely cause for this observation will be:
1. industrial pollutants turned the moths black
2. the selection pressure on the melanic and the non-melanic forms has reversed
3. genetic drift
4. assortative mating

What was the main point of difference between Darwin and Hugo de Vries regarding evolution?
| 1. | Darwin did not believe in the inheritance of acquired traits while Hugo de Vries did. |
| 2. | Evolution for Darwin was gradual while Hugo de Vries believed mutation caused speciation. |
