    Which of the following provides most evident proof of evolution?

    • Fossils

    • Morphology

    • Embryo

    • Vestigial organs

    Correct Answer
    A. Fossils
    Explanation
    Fossils provide the most evident proof of evolution because they are the preserved remains or traces of ancient organisms. By studying fossils, scientists can observe the changes in species over time, documenting the transition from one form to another. Fossils also provide evidence of extinct species and the development of new species. This tangible evidence supports the theory of evolution and allows scientists to reconstruct the history of life on Earth.

    Which compound has very important role in prebiotic evolution?

    • SO2

    • NO

    • CH4

    • SO3

    Correct Answer
    A. CH4
    Explanation
    CH4, also known as methane, has a very important role in prebiotic evolution. Methane is a simple organic compound that can be produced by both geological and biological processes. It is thought to have been abundant on early Earth and may have played a crucial role in the formation of the first organic molecules. Methane can act as a precursor for the synthesis of more complex organic compounds, such as amino acids, which are the building blocks of proteins. Additionally, methane can serve as a source of energy for early life forms, making it an important compound in prebiotic evolution.

    According to Oparin, which one of the following was not present in the primitive atmosphere of the earth?

    • Methane

    • Oxygen

    • Hydrogen

    • Water vapour

    Correct Answer
    A. Oxygen
    Explanation
    According to Oparin, oxygen was not present in the primitive atmosphere of the earth. Oparin's theory suggests that the early atmosphere was composed mainly of methane, hydrogen, and water vapor. Oxygen was absent because it was primarily produced by photosynthetic organisms, which evolved later in the history of the earth. This lack of oxygen in the early atmosphere was crucial for the development of life as we know it, as it allowed for the chemical reactions necessary for the formation of organic molecules and the emergence of early life forms.

    Thoms of Bougainvillea and tendrils of Cucurbita are examples of

    • Analogous organs

    • Homologous organs

    • Vestigial organs

    • Retrogressive evolution

    Correct Answer
    A. Homologous organs
    Explanation
    Thorns of Bougainvillea and tendrils of Cucurbita are examples of homologous organs. Homologous organs are those that have a similar structure and origin but may have different functions in different organisms. In this case, both thorns and tendrils are modified structures that have evolved from the same ancestral structure. They may serve different purposes in Bougainvillea and Cucurbita, but their similarity in structure suggests a common evolutionary origin.

    The finches of Galapagos islands provide an evidence in favour of

    • Special creation

    • Evolution due to mutation

    • Retrogressive evolution

    • Biogeographical evolution

    Correct Answer
    A. Biogeographical evolution
    Explanation
    The finches of the Galapagos islands provide evidence for biogeographical evolution because they have adapted to different environments on different islands, resulting in the development of different beak shapes and sizes. This adaptation is believed to have occurred through natural selection and genetic variation over time, supporting the idea that species can evolve and change in response to their environment.

    What is common to whale, seal and shark?

    • Seasonal migration

    • Thick subcutaneous fat

    • Convergent evolution

    • Homeothermy

    Correct Answer
    A. Convergent evolution
    Explanation
    Convergent evolution is the process where unrelated species evolve similar traits or characteristics in response to similar environmental pressures. In this case, all three animals (whale, seal, and shark) have evolved similar adaptations for life in the water, such as streamlined bodies, fins, and blubber. This similarity in adaptations is a result of convergent evolution, as these species are not closely related but have independently evolved similar traits to thrive in their aquatic habitats.

    When two species of different genealogy come to resemble each other as a result of adaptation, the phenomenon is termed as

    • Divergent evolution

    • Micro-evolution

    • Co-evolution

    • Convergent evolution

    Correct Answer
    A. Convergent evolution
    Explanation
    Convergent evolution occurs when two species from different genealogical backgrounds independently evolve similar traits or characteristics due to similar environmental pressures or adaptations. This can result in the species appearing similar in appearance or behavior, even though they are not closely related. This phenomenon is different from divergent evolution, which involves the development of different traits in closely related species, and co-evolution, which refers to the reciprocal evolutionary changes between two or more species.

    The most apparent change during the evolutionary history of Homo sapiens is traced in

    • Shorting of the jaws

    • Remarkable increase in the brain size

    • Loss of body hair

    • Walking upright

    Correct Answer
    A. Remarkable increase in the brain size
    Explanation
    The most apparent change during the evolutionary history of Homo sapiens is the remarkable increase in brain size. This change is significant because it distinguishes humans from other species and has played a crucial role in our cognitive abilities and development of complex societies. The increase in brain size allowed for the development of advanced thinking, problem-solving skills, language, and cultural advancements. It also led to the expansion of the neocortex, which is responsible for higher cognitive functions such as perception, consciousness, and reasoning. This change in brain size is a defining characteristic of the Homo sapiens species.

    A baby has been born with a small tail. It is the case exhibiting

    • Retrogressive evolution

    • Mutation

    • Atavism

    • Metamorphosis

    Correct Answer
    A. Atavism
    Explanation
    Atavism refers to the reappearance of a trait that was present in earlier generations but had disappeared in more recent ones. In this case, the baby being born with a small tail is an example of atavism because the trait of having a tail is a characteristic that was present in ancestral species but was lost in humans over time. The reappearance of this trait in the baby suggests a regression to an earlier form, demonstrating atavism.

    Which one of the following in birds indicates their reptilian ancestry?

    • Scales on their hind limbs

    • Four-chambered heart

    • Two special chambers crop and gizzards in their digestive tract

    • Egg with a calcareous shell

    Correct Answer
    A. Egg with a calcareous shell
    Explanation
    The presence of an egg with a calcareous shell in birds indicates their reptilian ancestry. This is because reptiles, like birds, also lay eggs with a hard shell made of calcium carbonate. This similarity suggests a common evolutionary history between birds and reptiles, supporting the idea of reptilian ancestry in birds.

    Echidna and Ornithorhynchus are the connecting links between

    • Amphibians and aves

    • Mammals and amphibians

    • Reptiles and mammals

    • Reptiles and amphibians

    Correct Answer
    A. Reptiles and mammals
    Explanation
    Echidna and Ornithorhynchus, also known as platypus, are unique mammals found in Australia. They possess characteristics that are common to both reptiles and mammals, making them the connecting links between these two groups. These characteristics include laying eggs like reptiles and possessing mammary glands and producing milk like mammals. Therefore, Echidna and Ornithorhynchus serve as evidence of the evolutionary relationship between reptiles and mammals.

    Origin of life as a result of chemical evolution has been properly explained by or the most logical biochemical theory of origin of life has been given by

    • Stanley Miller

    • Darwin

    • A I Oparin

    • S Fox

    Correct Answer
    A. A I Oparin
    Explanation
    A.I. Oparin is credited with providing the most logical biochemical theory of the origin of life through chemical evolution. Oparin proposed that life on Earth originated from simple organic molecules that formed in the early atmosphere and oceans. He suggested that these molecules underwent a series of chemical reactions, eventually leading to the formation of more complex organic compounds and the emergence of life. Oparin's theory laid the foundation for our understanding of how life could have arisen from non-living matter through natural processes.

    Which one of the following is incorrect about the characteristics of protobionts (coacervates and micro spheres) as envisaged in the abiogenic origin of life?

    • They were able to reproduce

    • They could separate combinations of molecules from the surroundings

    • They were partially isolated from the surroundings

    • They could maintain an internal environment

    Correct Answer
    A. They could maintain an internal environment
    Explanation
    The incorrect statement about the characteristics of protobionts is that they could maintain an internal environment. Protobionts, such as coacervates and microspheres, were able to separate combinations of molecules from the surroundings and were partially isolated from the surroundings. However, they were not capable of maintaining a stable internal environment like living organisms do. This is because protobionts lacked the complex cellular machinery and regulatory mechanisms that allow organisms to maintain homeostasis.
