The immediate reactions to On the Origin of Speciesthe book in which Charles Darwin described evolution by natural selectionincluded international debate, though the heat of controversy was less than that over earlier works such as Vestiges of Creation.

Darwin monitored the debate closely, cheering on Methods of stopping kinetic transesterification reactions biology essay Henry Huxley 's battles with Richard Owen to remove clerical domination of the scientific establishment. While Darwin's illness kept him away from the public debates, he read eagerly about them and mustered support through correspondence.

Religious views were mixed, with the Church of England 's scientific establishment reacting against the book, while liberal Anglicans strongly supported Darwin's natural selection as an instrument of God's design. Religious controversy was soon diverted by the publication of Essays and Reviews and debate over the higher criticism.

The most famous confrontation took place at the public Oxford evolution debate during a meeting of the British Association for the Advancement of Sciencewhen the Bishop of Oxford Samuel Wilberforce argued against Darwin's explanation. In the ensuing debate Joseph Hooker argued strongly in favor of Darwinian evolution.

Thomas Huxley's support of evolution was so intense that the media and public nicknamed him "Darwin's bulldog".

Charles Darwin

Huxley became the fiercest defender of the evolutionary theory on the Victorian stage. Both sides came away feeling victorious, but Huxley went on to depict the debate as pivotal in a struggle between religion and science and used Darwinism to campaign against the authority of the clergy in education, as well as daringly advocating the "Ape Origin of Man".

Background Darwin's ideas developed rapidly after returning from the Voyage of the Beagle in By Decemberhe had developed the basic principles of his theory. At that time, similar ideas brought others disgrace and association with the revolutionary mob.

He was conscious of the need to answer all likely objections before publishing. While he continued with research, he had an immense amount of work in hand analyzing and publishing findings from the Beagle expedition, and was repeatedly delayed by illness.

Natural history at that time was dominated by clerical naturalists who saw their science as revealing God's plan, and whose income came from the Established Church of England. Darwin found three close allies. The eminent geologist Charles Lyellwhose books had influenced the young Darwin during the Voyage of the Beaglebefriended Darwin who he saw as a supporter of his ideas of gradual geological processes with continuing divine Creation of species.

By the s Darwin became friends with the young botanist Joseph Dalton Hooker who had followed his father into the science, and after going on a survey voyage used his contacts to eventually find a position.

This was also a time of intense conflict over religious morality in England, where evangelicalism led to increasing professionalism of clerics who had previously been expected to act as country gentlemen with wide interests, but now were seriously focussed on expanded religious duties.

A new orthodoxy proclaimed the virtues of truth but also inculcated beliefs that the Bible should be read literally and that religious doubt was in itself sinful so should not be discussed.

Proud of our past, Excited about our Future

Science was also becoming professional and a series of discoveries cast doubt on literal interpretations of the Bible and the honesty of those denying the findings. A series of crises erupted with fierce debate and criticism over issues such as George Combe 's The Constitution of Man and the anonymous Vestiges of the Natural History of Creation which converted vast popular audiences to the belief that natural laws controlled the development of nature and society.

German higher criticism questioned the Bible as a historical document in contrast to the evangelical creed that every word was divinely inspired. Dissident clergymen even began questioning accepted premises of Christian morality, and Benjamin Jowett 's commentary on St.

Paul brought a storm of controversy. On 18 June he received a parcel from Alfred Russel Wallace enclosing about twenty pages describing an evolutionary mechanism that was similar to Darwin's own theory. Darwin put matters in the hands of his friends Lyell and Hooker, who agreed on a joint presentation to the Linnean Society on 1 July Darwin, as photographed in Publication of The Origin of Species Darwin now worked on an "abstract" trimmed from his Natural Selection manuscript.

The publisher John Murray agreed the title as On the Origin of Species through Natural Selection and the book went on sale to the trade on 22 November The stock of 1, copies was oversubscribed, and Darwin, still at Ilkley spa townbegan corrections for a second edition.

The novelist Charles Kingsleya Christian socialist country rector, sent him a letter of praise: First reviews The reviewers were less encouraging. Four days before publication, a review in the authoritative Athenaeum [5][6] by John Leifchildpublished anonymously, as was the custom at that time was quick to pick out the unstated implications of "men from monkeys" already controversial from Vestigessaw snubs to theologians, summing up Darwin's "creed" as man "was born yesterday — he will perish tomorrow" and concluded that "The work deserves attention, and will, we have no doubt, meet with it.

Scientific naturalists will take up the author upon his own peculiar ground; and there will we imagine be a severe struggle for at least theoretical existence. Theologians will say—and they have a right to be heard—Why construct another elaborate theory to exclude Deity from renewed acts of creation?

Why not at once admit that new species were introduced by the Creative energy of the Omnipotent? Why not accept direct interference, rather than evolutions of law, and needlessly indirect or remote action?

Having introduced the author and his work, we must leave them to the mercies of the Divinity Hall, the College, the Lecture Room, and the Museum. He would on no account burn me; but he will get the wood ready and tell the black beasts how to catch me.

Yet I infer from several expressions, that at bottom he goes immense way with us. It appears that Darwin had assured Owen that he was looking at everything as resulting from designed laws, which Owen interpreted as showing a shared belief in "Creative Power". Darwin had already made his views clearer to others, telling Lyell that if each step in evolution was providentially planned, the whole procedure would be a miracle and natural selection superfluous.

From Darwin discussed data with Andrew Ramsaywho had said "it is vain to attempt to measure the duration of even small portions of geological epochs.The kinetic analysis method using the non-isothermal technique was proposed to determine the kinetic parameters for the transesterification reaction of waste vegetable oil (WVO) in supercritical alcohols.

With an increasing search for new reactions at the microscale, or even improvement in the yields of well-established reactions, it is hardly surprising that some derivatization techniques originally developed for GC find an increasing use in mass spectrometry, high-performance liquid chromatography, laser spectroscopy, etc.
