Darwin got the idea of ‘common descent with modification’ as evolution initially from his observations on:
1. geographic distribution of species
2. fossil records
3. comparative embryology
4. comparative biochemistry

During which period of the geological time scale did the first seed plants evolve?
1. Carboniferous
2. Triassic
3. Jurassic
4. Cretaceous

The dominant plants during the Jurassic period were:
1. Bryophytes and Ferns
2. Gymnosperms
3. Monocots
4. Dicots

Which of the following will not counter natural selection?
1. genetic drift
2. gene flow
3. mutation
4. Unlimited resources

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

The fossils of Homo erectus were discovered in _____ and it existed about ____ mya.
1. Tanzania; 2
2. Java; 1.5
3. Ethiopia; 1.5
4. Australia; 2

Adenine was synthesized by Orgel, using the Miller apparatus, when he used the gas :
1. carbon dioxide
2. hydrogen cyanide
3. hydrogen sulfide
4. nitrogen

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

Identify the incorrectly matched pair:
1. Cretaceous period : dinosaurs became extinct
2. Carboniferous period : origin of reptiles
3. Silurian period : origin of vascular plants
4. Cambrian period : first vertebrates (jawless fishes)

de Vries based his “Mutation Theory” on his observation on :
1. Pisumsativum
2. Drosophila melanogaster
3. Oenotheralamackiana
4. Coenorhabditiselegans
