ORGANIC EVOLUTION Meaning and
Definition
-
Organic evolution is the scientific concept that refers to the gradual process of change, development, and diversification of living organisms over successive generations. This fundamental theory in biology posits that species undergo modifications in their traits and characteristics, which can lead to the emergence of new species over time.
The key mechanism driving organic evolution is natural selection, as proposed by Charles Darwin in his famous work "On the Origin of Species." Natural selection acts on individuals within a population, favoring those with advantageous variations that increase their chances of survival and reproduction. These favorable traits are then passed on to successive generations, gradually altering the composition and structure of the species.
Alongside natural selection, other factors contribute to organic evolution, such as genetic mutations, genetic drift, gene flow, and non-random mating. These processes introduce new genetic variations and facilitate their dissemination among populations, leading to further evolutionary changes.
Organic evolution encompasses both microevolutionary changes occurring within populations, such as changes in gene frequencies, and macroevolutionary changes that result in the formation of new species. The accumulation of small genetic changes over numerous generations can ultimately give rise to significant morphological, physiological, and behavioral transformations in organisms.
Understanding organic evolution is crucial as it provides a unifying framework for comprehending the immense diversity of life on Earth. It enables scientists to study the historical relationships between organisms, decipher their shared ancestry, and shed light on the processes that have shaped life as we know it today.

Etymology of ORGANIC EVOLUTION
The word "organic" in the context of biology and evolution comes from the Greek word "organikos", meaning "relating to an organ or instrument". It was first used in the 1770s by German naturalist and philosopher, Gottfried Große, to describe the study of living organisms. The term "organic evolution" itself was coined by British naturalist and biologist Charles Darwin in the mid-19th century to describe the gradual and orderly changes that occur in species over time. The word "evolution" is derived from the Latin word "evolutio", which means "unrolling" or "opening up", emphasizing the idea of gradual and unfolding change in species.
