In the case of peppered moth (Biston betularia), the black-coloured form became dominant over the light-coloured form in England during industrial revolution. This is an example of

1. natural selection whereby the darker forms were selected

2. appearance of the darker coloured individuals due to very poor sunlight

3. protective mimicry

4. inheritance of darker colour character acquired due to the darker environment

The first organisms were

2. chemoheterotrophs

3. autotrophs

4. eukaryotes
