BIO012- Evolution

    Cards (17)

    • What is evolution?
      Gradual change in living organisms
    • What does a phylogenetic tree represent?
      Evolutionary relationships among species
    • Who proposed the theory of natural selection?
      Charles Darwin
    • What are the steps of natural selection?
      1. Variation among individuals
      2. Overproduction of offspring
      3. Differential survival and reproduction
      4. Heritable traits passed to next generation
    • What is the first premise of natural selection?
      Heritable variation exists among individuals
    • What does overproduction of offspring lead to?
      Competition for limited resources
    • How does differential reproductive success affect evolution?
      Only certain individuals reproduce successfully
    • What is the significance of common ancestry in evolution?
      Species diverge from common ancestors
    • What is convergence in evolutionary biology?
      Unrelated species develop similar traits
    • How do species adapt to their environments?
      Through natural selection and evolution
    • What is the role of genetic variation in evolution?
      It provides the raw material for selection
    • What happens to species that cannot adapt?
      They may face extinction
    • How do environmental pressures influence evolution?
      They select for advantageous traits
    • What is the outcome of successful adaptation?
      Increased chances of survival and reproduction
    • How do genetic changes occur in populations over time?
      Through processes like mutation and selection
    • What is the significance of studying evolutionary patterns?
      It helps understand species adaptation and diversity
    • How do evolutionary biologists use phylogenetic trees?
      To trace evolutionary relationships among species
