Free Evolution MCQs with Answers

• A. Artificial selection
• B. Adaptation
• C. Variation
• D. Natural selection

Explanation: Darwin suggested that populations of individual species become better adapted to their local environments through natural selection.

• A. All were unique to individual islands
• B. Some were distributed on two or more islands
• C. Some were unique to individual islands
• D. Majority were unique to individual islands

Explanation: During his voyage on the Beagle, Charles Darwin collected 13 species of finches from the Galapagos Islands.

• A. Convergent
• B. Parallel
• C. Divergent
• D. Adaptive

Explanation: Analogous organs, like the wings of birds and bats, demonstrate convergent evolution because these structures serve similar functions but…

• A. Random mating
• B. Many mutations
• C. Frequent migrations
• D. Selected mating
• E. Random mutations

Explanation: Conditions for hardy-Weinberg equilibrium are as follows: No mutations (Crosses out E and B). No natural selection.

• A. Darker coloring of prepared moth near industrial areas
• B. Increased production of antibiotics by the fungus penicillium species
• C. Increased resistance of houseflies to the insecticide DDT
• D. Increased resistance of lichens to the heavy metals on tree bark around mine workings

Explanation: Artificial selection is an evolutionary process in which humans consciously select for or against particular features in organisms.

• A. I band II
• B. II and III
• C. I band III
• D. III and IV
• E. II and IV

Explanation: A. I is not right since a community involves different populations which may have different gene pool.B.

• A. Organisms produce more off springs than the environment can support
• B. Variation between individuals arises by gene mutation
• C. Only those individuals best adapted by environment survive and reproduce
• D. Individuals compete for scarce resources

Explanation: The idea that was not part of Charles Darwin's theory of evolution by natural selection is Option B: Variation between individuals arises…

• A. Convergent evolution
• B. Divergent evolution
• C. Co-evolution
• D. Artificial selection

Explanation: Due to different requirements or needs, some structures of the organisms have developed differently.

• A. Gene pool of the trait in the population
• B. Population density or total number of individuals in the population
• C. Tolal number of heterozygotes
• D. Total number of homozyotes

Explanation: The Hardy-Weinberg principle states that allele and genotype frequencies in a population will remain constant from generation to…

• A. Migration
• B. Mutation
• C. Selection
• D. Genetic drift

Explanation: Mutation is the most important factor in bringing about the origin of a new species.

• A. New Zealand
• B. New Guinea
• C. Galapagos Islands
• D. Australia

Explanation: Darwin finches (13 types) are found in the Galapagos islands, west of Ecuador.

• A. Darwin
• B. Lamarck
• C. Mendel
• D. Wallace

Explanation: Lamarckism, also known as Lamarckian inheritance or neo-Lamarckism, is the notion that an organism can pass on to its offspring physical…

• A. Vestigial Organs
• B. Comparative embryology organs
• C. Homologous organs
• D. None of the given options

Explanation: Homologous organs are referred to as the organs/traits that are inherited by two different organisms but from the same ancestry.

• A. Migration
• B. Genetic drift
• C. Mutation
• D. Non-random mating

Explanation: Genetic drift is the change in frequency of an existing gene variant in the population due to random chance.

• A. Regenerated organs
• B. Vestigial organs
• C. Saltatory organs
• D. Useless organs

Explanation: Vestigial organs are organs which are thought to be remnants of organs that once served some purpose but are now no longer functional or…

• A. Hairs
• B. Gill pouches
• C. Scales
• D. Fins

Explanation: Gill pouches were found to be present in the embryos of all vertebrates, even in air breathing reptiles and mammals.

• A. Cytochrome a
• B. Cytochrome b
• C. Cytochrome c
• D. Cytochrome d

Explanation: Cytochrome c: This option is the correct answer. Cytochrome c is a highly conserved respiratory protein found in a wide range of…

• A. Both artificial and natural selection
• B. Artificial selection
• C. None of these
• D. Natural selection

Explanation: Although Darwin discussed artificial selection to support his ideas, his core theory was built around natural selection, where nature, not…

• A. Comparative embroyology
• B. Distinct differences
• C. Vestigial organs
• D. Analogous structures

Explanation: Comparative embryology is the study of the similarities and differences in the embryos of different species to understand their…

• A. Homologous structures have similar structure but different functions
• B. Homologous structures have different structures but similar functions
• C. Homologous structures have neither similar structures nor similar functions
• D. Homologous structures have similar functions and similar external appearances

Explanation: Homologous structures are body parts that have a similar internal structure and origin but perform different functions, showing evidence…
