Options
- Aoverproduction, variations, constancy of population size, natural selection
- Bvariations, constancy of population size, overproduction, natural selection
- Coverproduction, constancy of population size, variations, natural selection
- Dvariations, natural selection, overproduction,constancy of population size
Correct answer
C. overproduction, constancy of population size, variations, natural selection
Step-by-step solution
Overproduction, variations, the constancy of population size, natural selection sequence was proposed by Darwin and Wallace for organic evolution. Overproduction: There is an overproduction of organisms due to high reproductive rate, even when the resources are limited. Even though the population increases enormously, the number of individuals in every generation remains constant. Variation: means differences, like you have black and white peppered moths, red, green capsicum and hundreds of colours of butterflies.
