3. Saltation

4. Retrograde evolution

Which of the following would lead to deviation from Hardy-Weinberg equilibrium?

The now extinct reptile group that evolved into mammals was:

3. Thecodants

4. Sauropsids

Identify the correct statement:

1. Dryopithecus was more man like than Ramapithecus

2. Homo Habilis probably did not eat meat

3. Homo Erectus had a cranial capacity of around 800 cc

Most fossils are found in:

Darwin believed that certain parts of the body get larger and more complex through the generations because they :

1. are used more extensively than other parts 

2. contribute to greater reproductive success

3. are pre-determined to do so 

4. are most similar to God's perfection 

The wings of a bird and that of an insect are:

1. Analogous structures

2. Homologous structure

3. Vestigial structures

4. Useless structures

Genetic drift occurs when a few individuals of a species colonize an island. The particular phenomenon is known as:

(a) The bottleneck effect

(b) The founder effect

(c) Assortative mating

(d) Random mating 

Directional selection favours:

(1) Both extremes of a trait

(2) Intermediate form of a trait

(3) Environmental differences

(4) One extreme form over the other extreme form and over intermediate forms of the trait
