Correct answer Carries: 4.

Wrong Answer Carries: -1.

Which of the following is incorrect?

Natural selection favors individuals with advantageous traits.
Coelacanth is an extinct species.
Embryological evidence supports common ancestry.
Industrial melanism is an example of natural selection.
2

Coelacanth is not extinct; it is considered a living fossil.

The theory that life originated from pre-existing non-living organic molecules is known as:

Theory of Special Creation
Panspermia
Chemical Evolution
Spontaneous Generation
3

Oparin and Haldane proposed the theory of chemical evolution, suggesting that life originated from non-living organic molecules.

Which of the following statements is correct?

Genetic drift is more significant in large populations.
Lamarck’s theory is based on natural selection.
Homo habilis was the first hominid to use tools.
Industrial melanism is unrelated to evolutionary biology.
3

Homo habilis, also known as the ‘handy man,’ was the first hominid to use stone tools.

Which of the following statements is correct?

Neanderthals had a brain size smaller than Homo habilis.
Hardy-Weinberg equilibrium is maintained when evolutionary forces act continuously.
Coelacanth is considered a living fossil.
Mutations always lead to evolutionary disadvantage.
3

Coelacanth is considered a living fossil, showing minimal evolutionary change over millions of years.

Which type of evolutionary evidence is provided by fossils found in different sedimentary layers?

Embryological Evidence
Biochemical Evidence
Paleontological Evidence
Anatomical Evidence
3

Paleontological evidence is provided by fossils found in different sedimentary layers, showing changes in life forms over time.

Which of the following is incorrect?

Genetic drift is more pronounced in small populations.
Mutation is the only source of genetic variation.
Adaptive radiation leads to the evolution of different species from a common ancestor.
Natural selection enhances the survival of advantageous traits.
2

Mutation is not the only source of genetic variation; genetic recombination also contributes to genetic diversity.

Which of the following is incorrect?

Fossils provide direct evidence of evolution.
Gene flow introduces new alleles into a population.
Analogous organs have similar structures but different functions.
Mutation introduces genetic variation in populations.
3

Analogous organs have similar functions but different structures and evolutionary origins.

Which of the following is incorrect?

Genetic recombination increases genetic diversity.
Industrial melanism is unrelated to environmental changes.
Mutation introduces new alleles into populations.
Fossil records provide evidence of extinct species.
2

Industrial melanism is related to environmental changes, such as pollution during the Industrial Revolution.

Which of the following is incorrect?

Industrial melanism is an example of natural selection.
Coelacanth is an extinct species.
Mutations can be beneficial, harmful, or neutral.
Fossils provide evidence for evolutionary relationships.
2

Coelacanth is not extinct; it is considered a living fossil, showing minimal evolutionary change.

Which species is considered the first to have exhibited bipedal locomotion?

Homo habilis
Australopithecus
Ramapithecus
Dryopithecus
2

Australopithecus is considered the first species to exhibit bipedal locomotion, a significant adaptation in human evolution.
