On Galapagos island, Darwin observed variation in beaks of birds (Darwin's finches) and he concluded:
1.  Inter species variation
2.  Intraspecies variation
3.  Natural selection according to food
4.  Inheritance of acquired characters

Homologous organs are:
1.  Wings of cockroach and wings of bats
2.  Wings of insects and wings of birds
3.  Air bladder of fishes and lungs of frog
4.  Pectoral fins of fishes and forelimbs of horse

Which evidence of evolution related to Darwin's finches:

1. Evidence from biogeographical distribution

2. Evidence from comparative anatomy

3. Evidence from embryology

4. Evidence from palaeontological

Similarities in organisms with different genotypes indicate:
1.  Microevolution
2.  Macroevolution
3.  Convergent evolution
4.  Divergent evolution

Which of the following are homologous organs:

1. Wings of Birds & Locust

2. Wings of birds (Sparrow) & Pectoral fins of fish

3. Wings of Bat & Butterfly

4. Legs of frog & Cockroach

Convergent evolution is illustrated by:

1. Rat and dog

2. Bacterium and protozoan

3. Starfish and cuttlefish

4. Dogfish and whale

Which one of the following describes correctly the homologous structures:
 

The age of fossils in the past was generally determined by the radio-carbon method and other methods involving radioactive elements found in the rocks. More precise methods, which were used recently and led to the revision of the evolutionary periods for different groups of organisms include:

1. Study of the conditions of fossilization

2. Electron spin resonance (ESR) & fossil DNA

3. Study of carbohydrates/proteins in rocks

4. Study of carbohydrates/proteins in fossils

Which of the following is the relatively most accurate method for dating fossils:

1. Electron-spin resonance method

2. Uranium-lead method

3. Potassium–argon method

4. Radio-carbon method
