Q.

Give an example of branching descent.

Q.

What is the relationship between speciation and adaptive radiation?

Q. According to Darwin, the organic evolution is due to

1. Interspecific competition
2. Intraspecific competition
3. Competition within closely related species
4. Reduced feeding efficiency in one species

1. A-genetics, B-evolution, C-ecology
2. A-physiology, B-evolution, C-ecology
3. A-population genetics, B-evolution, C-ecology
4. A-population genetics, B-evolution, C-morphology

Q. What are Eurythermal species?

Q. The process by which heritable variations enabling better survival, enable an organism to reproduce and leave greater number of progeny is called

1. Genetic drift
2. Mutation
3. Founder effect
4. Natural selection

Q.

What is said to be the end result of the capability to adapt and get selected by nature?

Q.

Who and when was the term ‘evolution’ used?

Q. Short term adaptations are though temporary changes but are inherited in the next generation - true or false.

Q. Analogous organs arise due to:

1. divergent evolution
2. convergent evolution
3. artificial selection
4. genetic drift

Q. Those who are better fit in an environment are hence selected by nature. This leads to the mechanism of evolution. Which theory suggests this?

1. Theory of natural selection
2. Theory of germplasm
3. Origin of species
4. Survival of fittest

1. Lamarck
2. Darwin
3. Wallace
4. Oparin

Q.

What statement describes natural selection?

Q. Darwin and Wallace’s theory of evolution by natural selection failed to explain how
Statement 1: Nature operates to reduce variations in a population every generation.
Statement 2: New genetic variations can appear in a population every generation.
Statement 3: Variations lead to evolution, useful variations are transmitted to the next generation and other variations are eliminated.

Choose the correct option

1. Statement 1 only
2. Statement 2 only
3. Statement 3 only
4. Statement 1 and 3
