Correct Answer - Option 1 : Adaptation

The correct answer is Adaptation.

  • The reason for large-scale diversity among the organisms is Adaptation.
  • Adaptation:
    • The meaning of adaptation implies how a species changes its body and behavior to better suit its natural environment.
    • There are an estimated 8.7 million species currently living on earth.
    • They are found across a wide and diverse natural environment, ranging from frozen and desolate Arctic to the sweltering sands of the Sahara.
    • The natural environment is an ever-changing feature of planet earth.
    • The process of adaptation ensures that the species which adapts the most, survive.

  • Polyploidy:
    • It is a condition in which the cells of an organism have more than two paired sets of chromosomes.
    • Polyploidy, the condition in which a normally diploid cell or organism acquires one or more additional sets of chromosomes.
    • In other words, the polyploid cell or organism has three or more times the haploid chromosome number. Polyploidy arises as to the result of the total nondisjunction of chromosomes during mitosis or meiosis.
  • Mutation:
    • Any change in a gene that is heritable is known as Mutation.
    • Mutation, an alteration in the genetic material (the genome) of a cell of a living organism or of a virus that is more or less permanent and that can be transmitted to the cell’s or the virus’s descendants.
    • Mutation in the DNA of a body cell of a multicellular organism (somatic mutation) may be transmitted to descendant cells by DNA replication and hence result in a sector or patch of cells having an abnormal function, an example being cancer.
    • Mutations in egg or sperm cells (germinal mutations) may result in an individual offspring all of whose cells carry the mutation, which often confers some serious malfunction, as in the case of human genetic diseases such as cystic fibrosis.
  • Cooperation:
    • It is the process of groups of organisms working or acting together for common, mutual, or some underlying benefit, as opposed to working in competition for selfish benefit.
    • Many animal and plant species cooperate both with other members of their own species and with members of other species.
