The similarity of bone structure in the forelimbs of many vertebrates is an example of:

1. Homology
2. Analogy
3. Convergent evolution
4. Adaptive radiation

1. Forelimbs of man, bat and cheetah
2. Heart of bat, man and cheetah
3. Brain of bat, man and cheetah
4. Eye of octopus, bat and man

Genetic drift operates in:

1. small isolated population

2. large isolated population

3. non-reproductive population

4. slow reproductive population

The chronological order of human evolution from early to the recent is?

Which is the most common mechanism of genetic variation in the population of a sexually reproducing organism?

Variation in gene frequencies within populations can occur by chance rather than by natural selection. 
This is referred to as:

1. Genetic drift

2. Random mating

3. Genetic load

4. Genetic flow

Darwin's finches are a good example of:

1. industrial melanism

2. connecting link

3. adaptive radiation

4. convergent evolution

Given that the frequency of children homozygous for the recessive allele for cystic
fibrosis is about 0.0016. What is the frequency of heterozygotes in the population? [Cystic fibrosis is inherited as an autosomal recessive disorder].

1. 0.960

2. 0.077

3. 0.040

4. 0.923

Peripatus is a connecting link between:

1. Ctenophora and Plantyhelminthes

2. Mollusca and Echinodermata

3. Annelida and Arthropoda

4. Coelenterata and Poriphera
