MODERN SYNTHESIS Meaning and
Definition
-
The "modern synthesis" is a term that refers to a major milestone in the field of biology, particularly in the study of evolution. It represents the integration of various disciplines within biology with the theory of evolution proposed by Charles Darwin. The modern synthesis emerged in the mid-20th century and sought to reconcile the mechanisms of inheritance, genetics, and evolution, thus creating a comprehensive understanding of how life evolves.
At its core, the modern synthesis recognizes that genetic variation, driven by mutation and recombination, is the raw material upon which natural selection acts. It acknowledges that the genetic information is stored in DNA molecules, and that changes in these molecules are responsible for variations in traits across generations. This perspective incorporates the concept of gradualism, highlighting that evolution generally occurs through a slow and steady accumulation of small changes over long periods of time.
The modern synthesis also recognizes the importance of population genetics, which studies the genetic composition and dynamics of populations. This field emphasizes factors such as gene flow, genetic drift, and population size in influencing the frequency of different genetic variations within a population. It also incorporates the idea of speciation, detailing the processes by which new species arise over time.
Overall, the modern synthesis is a comprehensive framework that provides a unified understanding of genetics, inheritance, and evolution. It has greatly influenced the field of biology, serving as the foundation for modern evolutionary biology and driving further research and discoveries in the field.
Etymology of MODERN SYNTHESIS
The word "modern synthesis" is a term coined in the field of biology in the 1940s to describe the merging of two previously competing theories: Darwinian evolution and Mendelian genetics. The etymology of the term can be broken down as follows:
1. "Modern": This word originated from the Latin word "modernus", which means "of the present time" or "recent". In this context, it signifies the merging of the ideas of Darwinian evolution and Mendelian genetics during the 20th century.
2. "Synthesis": This word derives from the Greek word "synthesis", meaning "combination" or "composition". It refers to the blending and integration of different ideas or theories into a unified whole.
Therefore, the etymology of the term "modern synthesis" suggests the combination of Darwinian evolution and Mendelian genetics into a unified theory of evolution, which has become the foundation of modern biology.
