Microevolution
Microevolution is the study of small-scale changes in the genetic makeup of populations over time.
Evolution
Evolution is the process of change in all forms of life over generations, driven by mechanisms such as mutation, natural selection, and genetic drift. This category covers the history of evolutionary thought, the mechanisms of evolution, and the diversity of life on Earth. From exploring the origins of species to understanding the evolutionary relationships between different organisms, learn about the science behind the history of life on our planet.
Oparin-Haldane Hypothesis
The Oparin-Haldane Hypothesis, also known as the primordial soup theory, proposes that life on Earth originated from simple organic compounds that formed in the atmosphere and oceans of the early Earth.
Theories of Evolution
Theories of evolution attempt to explain how species have changed over time and how new species arise.
Theory of Epigenesis
The Theory of Epigenesis is a scientific concept that seeks to explain the origin and development of organisms through the gradual differentiation of cells.
Macroevolution
Macroevolution refers to the long-term patterns and processes of evolution that occur over geological time scales, typically involving the formation of new species and the diversification of entire groups of organisms.
Theory of Isolation
The theory of isolation is a post Darwinian theory put forth by Moritz Wagner. Wagner believed that Darwin was not able to explain the concept of speciation completely.
Theory of Spontaneous Generation
The theory of spontaneous generation is the idea that living organisms originated from seemingly non-living beings, or even totally inorganic matter.
Molecular Evolution
Molecular evolution is the study of the changes that occur in DNA and protein sequences over time, and how these changes relate to the evolutionary history and relationships of different species.
Neutral Theory of Evolution
According to the neutral theory of evolution, the bulk of molecular variation has no influence on fitness, so random processes are the most likely cause of genetic variation.
Industrial Melanism
When artificial impacts on natural selection have caused a species' color to change, it is known as industrial melanism.
Theory of Mutation in Evolution
Hugo de Vries, a Dutch botanist and geneticist, first put out the theory of mutation stating that the new species emerge
Out of Africa Theory
In-depth inquiries into the ancestry of Homo sapiens, or modern humans, have been done throughout history. One method is the "multi-regional hypothesis of human evolution".
