Correct answer Carries: 4.

Wrong Answer Carries: -1.

Which of the following is incorrect?

Mutation can be beneficial, harmful, or neutral.
Genetic drift can lead to significant changes in large populations.
Embryological evidence supports the theory of common ancestry.
Adaptive radiation leads to the formation of diverse species from a common ancestor.
2

Genetic drift has a significant effect in small populations, not large populations.

Which of the following statements is correct?

Coelacanth is an extinct species that links fish and amphibians.
Genetic drift is more significant in large populations.
Homologous organs provide evidence for convergent evolution.
Homo erectus used tools and fire during its existence.
4

Homo erectus used tools and fire, marking an important stage in human evolutionary development.

Which era is known for the dominance of dinosaurs?

Paleozoic Era
Mesozoic Era
Cenozoic Era
Proterozoic Era
2

The Mesozoic Era is often called the ‘Age of Reptiles’ due to the dominance of dinosaurs.

Which evolutionary concept explains the development of similar features in species with no common ancestry?

Divergent Evolution
Convergent Evolution
Parallel Evolution
Co-evolution
2

Convergent evolution refers to the development of similar traits in species with no common ancestry due to similar environmental pressures.

What led to the rapid increase in the population of melanic moths during the Industrial Revolution?

Increased pollution
Habitat loss
Predation on white moths
Climate change
3

Predation on white moths increased due to pollution darkening tree trunks, favoring melanic moths' survival through camouflage.

Which geological period marked the first appearance of vertebrates?

Cambrian
Ordovician
Devonian
Silurian
1

The Cambrian period marked the first appearance of vertebrates, as part of the Cambrian Explosion.

Which of the following is incorrect?

Embryological evidence supports evolutionary relationships.
Darwin’s finches are an example of convergent evolution.
Reproductive isolation can lead to speciation.
Mutation is a source of genetic variation in populations.
2

Darwin’s finches are an example of adaptive radiation, not convergent evolution.

Which of the following statements is correct?

Homo sapiens appeared before Homo habilis.
Mutation introduces genetic variation in populations.
Adaptive radiation is also known as convergent evolution.
Hardy-Weinberg equilibrium is maintained when evolutionary forces act continuously.
2

Mutation introduces new genetic variations, contributing to evolutionary change.

Who proposed that giraffes evolved long necks by stretching to reach higher leaves?

Charles Darwin
Jean-Baptiste Lamarck
Hugo de Vries
Alfred Wallace
2

Jean-Baptiste Lamarck suggested that giraffes developed long necks through the use and disuse of organs, though this idea has been rejected.

Which of the following is incorrect?

Fossils provide evidence for evolutionary history.
Mutation always leads to harmful genetic changes.
Gene flow reduces genetic variation between populations.
Homo habilis is known as the ‘handy man’ for using tools.
2

Mutations can be beneficial, harmful, or neutral depending on the context and environment.
