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.
