An analysis of the theories of darwin and wallace

Notes and References Abstract Only a few years after the publication of Darwin's On the Origin of Species, Alfred Russel Wallace made public his opinion that natural selection was not an all-sufficient cause of the evolution of man--particularly, as regards the higher human faculties moral, artistic, and mathematical abilities, etc. Most workers have drawn the direct conclusion that Wallace "changed his mind" about the theory he originally set out--perhaps because of an inability to reconcile "the survival of the fittest" concept with his utopian social views, or in conjunction with his adoption of spiritualist beliefs. In the present work a different interpretation of the events is presented:

The following is the transcript of Professor H. James Birx In the middle of the last century, Charles Robert Darwin presented a scientific theory of organic evolution.

His view of life challenged traditional biology and represented a conceptual revolution that has altered forever how we interpret the universe, life on this planet, and the human being within nature. However, Darwin himself was disturbed by the philosophical implications and theological consequences of his discovery that species are, in fact, mutable.

Taking Darwin seriously, the entrenched static view of life forms is replaced by a dynamic conception of the living world throughout earth history. Furthermore, this naturalistic interpretation of reality holds far-reaching ramifications for the beliefs that humankind is both separated from but occupies a special place in nature.

Darwinian evolution has replaced the anthropocentric and theocentric cosmology with a universe that is utterly indifferent to the evolution of life in general, and the emergence of our own species in particular.

Among the ancient Greek philosophers, Aristotle argued that appearance is reality. He taught that nature is a ladder of forms or a great chain of being from minerals, through plants and animals, to the human being.

Grounded in teleology[1] and essentialism,[2] his biology maintained the eternal fixity of all species. In fact, the Aristotelian worldview claimed that nature had no beginning and will have no end. It ignored fossils, denied extinctions, and consequently rejected the idea of evolution.

Clearly, Aristotelian philosophy and Darwinian evolution are mutually exclusive interpretations of life on earth. Among the Romans, the philosopher Lucretius presented a materialistic view of this universe in his poetic work On the Nature of Things.

He held that the earth itself had given birth to plants and animals including the human being. Because they contradicted the prevailing Greek worldview, Lucretius' ideas were unacceptable to the Aristotelians.

Analyzing Wallace’s “Species Notebook,” Costa shows how Wallace’s methods and thought processes paralleled Darwin’s, yet inspired insights uniquely his own. Kept during his Southeast Asian expeditions of the s, the notebook is a window into Wallace’s early evolutionary ideas. Wallace had once briefly met Darwin and was one of the correspondents whose observations Darwin used to support his own theories. Wallace trusted Darwin’s opinion on the matter and sent him his February essay titled “On the Tendency of Varieties to Depart Indefinitely from the Original Type.”. Only a few years after the publication of Darwin's On the Origin of Species, Alfred Russel Wallace made public his opinion that natural selection was not an all-sufficient cause of the evolution of man--particularly, as regards the higher human faculties (moral, artistic, and mathematical abilities, etc.). Most workers have drawn the direct.

During the Italian Renaissance, Giordano Bruno argued that this universe is eternal in time, infinite in space and endlessly changing. Furthermore, advocating pantheism, he maintained that God and nature are one and the same thing. In doing so, his bold cosmic perspective challenged both the Thomists and Aristotelians.

The traditional theistic interpretation of this universe and the new Brunian cosmology were mutually exclusive views of the world. As a result, Bruno was condemned as a heretic. Inhe was burned alive at the stake in Rome. In astronomy, however, the subsequent discoveries by Kepler and Galileo among others helped to demolish the ancient and medieval conceptions of this universe.

Nevertheless, it still remained for a naturalist to replace a static view of life forms with an evolutionary interpretation of all species.Apr 30,  · He Helped Discover Evolution, And Then Became Extinct Charles Darwin is known as the father of evolution.

Darwin now wears the crown of convention and orthodoxy burdened by these persistent anomalies, so we would do well to remember on this centennial of Wallace’s passing (November 7th ) that the co-discoverer of natural selection remains Darwin’s heretical heir apparent.

On the Tendency of Species to form Varieties; and on the Perpetuation of Varieties and Species by Natural Means of Selection is the title of a joint presentation of two scientific papers to the Linnean Society of London on 1 July On The Tendency of Varieties to Depart Indefinitely from the Original Type by Alfred Russel Wallace and an Extract .

Wallace had once briefly met Darwin and was one of the correspondents whose observations Darwin used to support his own theories. Wallace trusted Darwin’s opinion on the matter and sent him his February essay titled “On the Tendency of Varieties to Depart Indefinitely from the Original Type.”.

Outline in detail Darwin’s idea of ‘natural selection’, and explain how this differed from previous evolutionary theories. Charles Darwin () was a British naturalist who is famously associated with the term ‘natural selection’ which he believed was the process that caused species to evolve.

In this essay I aim to explain Darwin’s theory of evolution through natural.
