evolution Chapter-Wise Test 1

Correct answer Carries: 4.

Wrong Answer Carries: -1.

Which process involves the selection of individuals with traits best suited for their environment?

Artificial Selection
Natural Selection
Gene Flow
Genetic Drift
2

Natural selection favors individuals with advantageous traits, allowing them to survive and reproduce.

Which of the following is incorrect?

Gene flow can introduce new alleles into a population.
Adaptive radiation results in species diversity from a common ancestor.
Coelacanth is considered a living fossil.
Hardy-Weinberg equilibrium describes continuous changes in allele frequencies.
4

Hardy-Weinberg equilibrium describes the stability of allele frequencies in the absence of evolutionary forces.

Which of the following is incorrect?

Darwin’s theory is based on natural selection.
Coelacanth is considered a living fossil.
Adaptive radiation is also known as convergent evolution.
Mutation introduces new genetic variations into populations.
3

Adaptive radiation is not convergent evolution; it refers to the diversification of species from a common ancestor.

Which scientist disproved the theory of spontaneous generation?

Stanley Miller
Charles Darwin
Louis Pasteur
Hugo de Vries
3

Louis Pasteur demonstrated that life does not originate spontaneously but comes from pre-existing life.

What does the presence of vestigial gill slits in human embryos suggest?

Common ancestry with fishes
Evidence of convergent evolution
Adaptation to terrestrial life
Result of genetic mutation
1

Vestigial gill slits in human embryos suggest common ancestry with aquatic organisms like fishes.

Which evolutionary concept is demonstrated by the variety of finches observed by Darwin on the Galapagos Islands?

Convergent Evolution
Adaptive Radiation
Parallel Evolution
Co-evolution
2

Adaptive radiation is demonstrated by Darwin’s finches, where species evolved from a common ancestor to adapt to different ecological niches.

Which of the following is an example of genetic drift?

Industrial Melanism
Bottleneck Effect
Natural Selection
Gene Flow
2

The bottleneck effect is an example of genetic drift, where a population’s size is drastically reduced, altering gene frequencies.

Which of the following experiments demonstrated the synthesis of organic molecules under primitive Earth conditions?

Pasteur’s Swan Neck Flask Experiment
Miller-Urey Experiment
Hardy-Weinberg Principle
Griffith’s Transformation Experiment
2

The Miller-Urey experiment simulated early Earth conditions and led to the formation of organic molecules like amino acids.

Which of the following is incorrect?

Paleontology provides evidence for evolutionary relationships.
Industrial melanism is an example of natural selection.
Hardy-Weinberg equilibrium describes changes in allele frequencies over time.
Oparin and Haldane proposed the theory of chemical evolution.
3

Hardy-Weinberg equilibrium describes the stability of allele frequencies in a population in the absence of evolutionary forces.

Which species is considered the first to walk upright in human evolutionary history?

Homo sapiens
Australopithecus
Homo habilis
Ramapithecus
2

Australopithecus is considered the first species to walk upright in human evolutionary history.
