Is Darwinism The Same As Evolution?

No, they are not the same. Evolution is often mistaken for Darwinism on the whole when they are just closely related to each other.

Evolution is not progressive, reproducing “good quality” organisms, but it only seeks to design adaptations. It is the gradual development of living entities believed to have developed from earlier forms of life on earth.

Depending upon the context, the meaning of evolution can vary. It does not necessarily have to refer to Darwinism, which is only a theory stating that eventual changes in a species led to a shift in their appearance through the natural selection process. A species is a living entity that is capable of reproduction with its own kind. Through natural selection, species are able to transfer genetic attributes from one generation to another, so as to better adapt to their surroundings, hence the survival of the fittest. Most scientists apply to the term Darwinism when they refer to evolution, but in fact, they are two separate concepts and need to be addressed carefully. Charles Darwin proposed a theory after observing changes through generations. Many scientists have tried to put forward theories related to evolution but did not succeed. Darwin’s theory still stands as the theory of evolution. It has two main aspects that shape the inheritance of alleles within a particular population – Natural Inheritance and Adaptations. He observed the following:

  • Population size would increase exponentially if all the individuals that take birth reproduce successfully
  • Except for seasonal fluctuations, populations usually tend to stay stable in terms of size
  • Limitation in environmental resources
  • A population varies extensively in their traits or characteristics which influences their ability to reproduce and survive
  • Variations can be inherited as they are genetic

Differences Between Darwinism And Evolution

Listed below are a few differences between Darwinism and evolution that would help us understand better.

 

Darwinism Evolution
Proposed by Charles Darwin, is a theory of evolution of species through natural selection Over successive generations, it is the change in the heritable traits of biological populations
It is a theory of evolution It is the changes observed in a particular population with time
Natural Selection Gene flow, inbreeding, genetic drift, hybridization, natural selection
Noticeable changes take place in a short period of time Noticeable changes take place over millions of years
Through means of sexual reproduction such as crossing over and mixing alleles, genetic variations arise Takes place through genetic variations, overproduction, struggle for existence, natural selection and survival of the fittest
Example – Light brown deer mice, short neck and long neck giraffes. Example – Shortening of the external ear pinna, the disappearance of tail bones in humans
