Which of the following would be an example of a population that can show the potential for rapid speciation?
1. small in number but highly variable gene pool
2. large in number with large variations in the gene pool
3.sexual dimorphism amongst members
4.isolated inbred population

In modern terms, selection refers to :
1. inheritance of dominant characters
2. differential reproduction
3. a decrease in allele frequency in a population
4. differences in the contribution of various genotypes to the next generation

Adaptive radiations refers to 
1. Power of adaptation in an individual to a variety of environments.
2. Adaptations due to geographical isolation.
3. Evolution of different species from a common ancestor.
4. Migration of members of a species to different geographical areas.
 

What exactly does the nature act upon when selecting an organism?
1. dominant alleles
2. recessive alleles
3. phenotype
4. combined genotype

Darwin's in his natural selection Theory did not believe in any role of which one of the following in organic evolution?  
1. Parasites and predators as natural enemies
2. Survival of the fittest
3. Struggle for existence
4. Discontinuous variations 
 

Both Charles Darwin and A.R.Wallace were influenced by the:
1. writings of J.B.S.Haldane on the origin of life
2. findings of Urey and Miller experiments
3. findings on the Galapagos Islands
4. essay on human population by T.R.Malthus

The ‘phrase’ that will best describe ‘Natural Selection’ will be:
1. differential success in reproduction
2. differential mortality
3. assortative mating
4. descent with modification

Diversification in plant life appeared:

1. Due to abrupt mutations

2. Suddenly on earth

3. By seed dispersal

4. Due to long periods of evolutionary changes 

In Darwinian terms “fitness” can best be described as:
1. ability of organism, relative to others in the population, to pass its genes to next generation
2. the number of mates the organism has during its life time
3. its lifespan
4. its physical vigor
