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.

What is Speciation in Anthropology

Speciation

Speciation refers to the process by which new species arise from existing ones. It is a fundamental concept in evolutionary biology that explains the diversity of life on our planet.

Adaptive Radiation in Anthropology

Adaptive Radiation

Adaptive radiation is a biological phenomenon in which a single ancestral species rapidly diversifies into multiple new species, each adapted to a specific ecological niche or habitat.

Theory of Preformationism in Anthropology

Preformationism

Preformationism, also known as the theory of preformation, is a biological theory that originated in the 17th century and posits that all organisms develop from preexisting miniature versions of themselves, called "homunculi."

Miller-Urey Experiment in Anthropology

Miller-Urey Experiment

Stanley Miller and Harold Urey in 1953 tested the Oparin – Haldane Theory and were successful in producing the organic molecules from some inorganic

Modern Synthetic Theory of Evolution in Anthropology

Modern Synthetic Theory of Evolution

The modern synthetic theory of evolution is founded on the idea of genes, which are hereditary in nature and aid in passing down traits from one generation to the next. It combines the ideas of Mendelian genetics with Darwinian evolution.

Theory of Use and Disuse in Evolution

Theory of Use and Disuse

The ‘theory of use and disuse’ refers to the concept that all organisms physically adjust to their environment in ways that these new physical characteristics could be inherited by their offspring.
