Þróunarfræðinnin
Þróunarfræðinnin, often translated as evolutionary theory, is the scientific understanding of the origin and diversification of life on Earth. It proposes that all living organisms share a common ancestor and have changed over vast periods of time through a process of natural selection. This process favors individuals with traits that enhance their survival and reproduction in a particular environment, leading to the gradual accumulation of these advantageous characteristics within a population.
Key components of evolutionary theory include the concepts of variation, inheritance, and selection. Variation refers to
Evidence supporting evolutionary theory comes from a wide range of scientific disciplines. The fossil record provides
While the core principles of evolutionary theory have been established for over a century, scientific research
