• A. Vital Organs
• B. Homologous Organs
• C. Vestigial Organs

Explanation: Homologous organs are created in divergent evolution. Homologous organs refer to the organs with similar structures but having different…

• A. Analogous organs
• B. Homologous organs
• C. Autologous organs
• D. Anuclogous organs

Explanation: Organs that have the same internal structure but perform different functions are called homologous organs.Homologous organs result from…

• A. Fossil record
• B. Common ancestor organisms
• C. Vestigial structures
• D. None of these

Explanation: The correct answer is that none of the options provided are not evidence of evolution.

• A. The significance of minute variations
• B. Presence of vestigeal or useless organs
• C. The presence of over specialized organs
• D. All of the above

Explanation: 'Darwin's theory' was based on variations, struggle, natural selection, and differential reproduction.

• A. Taxonomic
• B. Phylogenetic
• C. Homologous
• D. Analogous

Explanation: The correct answer is " analogous." The wings of birds and beetles are considered analogous because they both serve the function of flight…

• A. Organisms ranged from simple to complex
• B. One type of organism gives rise to another type of organism
• C. Both A & B
• D. All living things were specially created by nature

Explanation: The correct answer is Both A & B. Aristotle recognized a natural order from simple to complex organisms, and while he did not propose a…

• A. Mammals
• B. Fishes

Explanation: Archaeopteryx is thought to be earliest bird whose fossils have been found from rocks 150 million years old.

• A. Insects
• B. Pisces
• C. Amphibians
• D. Reptiles

Explanation: With the exception of feathers, archaeopteryx showed resemblance to the dinosaurs (giant reptiles of past).

• A. Vestigial organ
• B. Domestication
• C. Mutation
• D. Homology

Explanation: Domestication means artificial selection in breeding provides evidence for evolution.Example: Vast diversity has been achieved in domestic…

• A. Nitrogen
• B. Potassium
• C. Sulphur
• D. Calcium

Explanation: Carnivorous plants live in environments where there is deficiency of nitrogen, in order to supplement their diet with nitrogen, they trap…

• A. "Survival in the struggle for existence is random"
• B. The fit individuals leave more off springs into their environment
• C. The unequal ability of individuals to survive and reproduce will lead to a gradual
• D. Accumulation over the generations thus leading to the evolution of a new species

Explanation: Survival in the struggle for existence is random: This statement is not correct for Darwin's theory of natural selection.

• A. Natural selection
• B. Evolution
• C. Genetic drift
• D. Artificial selection

Explanation: When humans purposefully apply selection pressure to populations, such as in breeding programs for plants or animals, it is known as…

• A. The genes were selectively advantageous.
• B. The genes were dominant.
• C. The genes were sex-linked.
• D. The population increased.

Explanation: The correct answer is that the frequency of a mutant gene in a population is likely to increase if the gene is selectively advantageous.

• A. Snake's legs
• B. Natural selection
• C. Muscle atrophy
• D. Movement of ear

Explanation: Natural selection: Correct, as the main point of Darwinism is the theory of natural selection, which explains how traits that are…

• A. 2.5 billion years ago
• B. 3.5 billion years ago
• C. 4.5 billion years ago
• D. 5.5 billion years ago

Explanation: Prokaryotes are believed to take origin around 3.5 billion years ago

• A. Vestigial organs
• B. Homologous organs
• C. Analogous organs
• D. Embryonic organs

Explanation: The type of organs that are supposed to be functional in ancestral species rather than in present-day species are Vestigial…

• A. Equus
• B. Python
• C. Archaeopteryx
• D. Dawn horse

Explanation: The correct answer is Archaeopteryx, which is a significant fossil in the study of evolution as it exhibits both avian and non-avian…

• A. All were unique to individual islands
• B. All finches were red-beaked
• C. Some were unique to individual islands, and some were present on many islands
• D. The majority were unique to individual islands

Explanation: Among the birds Darwin collected on the Galapagos were 13 types of finches that, although quite similar, seemed to be different species.
