The number of species on island depends on the size of the island and its distance from mainland. This statement would most likely be made by _______________.

• a geologist

• an explorer

• a philosopher

• a biogeographer

The first comprehensive theory of evolution, which proposed that the mechanism was an inner drive for improvement, was proposed by _______________.

• Aristotle

• Lamarck

• Wallace

• St Hillarie

Presence of vestigial body parts in organisms like coccyx in human and leg bones in snakes _______________.

• challenge prevailing beliefs

• support idea on evolution

• add up naturalist confusion

• all of the above

Porpoise flippers, human arms, bat wings and elephat’s leg are different outwardly but have similar form internally. This shows they have_________________.

• common ancestory

• common eating behaviour

• common habitat

• all of the above

Organs of different organisms that have a similar form due to a common origin are ______________.

• Homoplastic

• Homologous

• Vestigial

• Analogous

These are inferences made in the Principle of Natural Selection except:

• Individuals with less adaptive traits cannot survive.

• Adaptive traits may make an individual better suited to an environment.

• Individuals that better suited to environment are better able to survive tend to leave more offsprings

• Frequency of adaptive tends to become more common in a population over time.

The first to propose that the mechanism for the evolution of organisms is by natural selection was _________________.

• Malthus

• Lamarck

• Darwin

• Wallace
