Evolution

    Cards (21)

    • The theory of evolution is the unifying principle that explains all biological phenomena.
    • Evolutionary biology is the scientific discipline concerned with understanding how life has changed over time, including the mechanisms driving change and the patterns of variation among living things.
    • Darwin's finches are an example of adaptive radiation, where different species evolve from a common ancestor to occupy different niches within an ecosystem.
    • Variation refers to differences between individuals within a species, which can be caused by genetic mutations or environmental factors.
    • Evolutionary biology, also known as Darwinism or neo-Darwinism, is based on three fundamental principles: variation, inheritance, and natural selection.
    • Inheritance involves passing traits from parents to offspring through genes.
    • Adaptation refers to traits or characteristics that increase an organism's fitness (ability to survive and reproduce) in its environment.
    • Natural selection is the process by which individuals with advantageous traits have higher reproductive success than those without them, leading to changes in populations over generations.
    • Mutations are random changes in DNA sequences that can lead to new genetic variants in offspring.
    • Natural selection occurs when certain traits become more prevalent in a population due to their advantageous nature, leading to adaptation and survival.
    • Adaptation is the process by which organisms develop characteristics that enable them to better survive and reproduce in their environment.
    • Natural selection is the process by which organisms better adapted to their environment survive and reproduce more successfully than less well-adapted ones.
    • Adaptation is any trait that increases an individual's chances of survival and reproduction in its current environment.
    • Fitness is a measure of reproductive success, determined by the number of offspring produced relative to other members of the population.
    • Speciation is the process by which new species arise from existing ones.
    • Adaptation is the process by which organisms develop characteristics that enable them to survive and reproduce in their environment.
    • Natural selection occurs when certain traits become more prevalent in a population due to their advantageous nature.
    • Natural selection occurs when certain variations give individuals a better chance of survival and reproduction than others, leading to changes in populations over time.
    • The theory of evolution states that all living things have evolved over time from common ancestors through processes such as natural selection and adaptation.
    • Charles Darwin proposed the idea of evolution by natural selection in his book "On the Origin of Species" published in 1859.
    • The theory of evolution states that all living things share a common ancestry and have evolved over time through processes such as natural selection and adaptation.
