Darwin and His Theory of Evolution | Pew Research Center

New features require new variations. In the modern version of Darwin’s theory, these come from DNA mutations. Most DNA mutations are harmful and are thus eliminated by natural selection. A few, however, are advantageous — such as mutations that increase antibiotic resistance in bacteria and pesticide resistance in plants and animals. Antibiotic and pesticide resistance are often cited as evidence that DNA mutations provide the raw materials for evolution, but they affect only chemical processes. Major evolutionary changes would require mutations that produce advantageous anatomical changes as well.

Erasmus Darwin's work includes the following acceptance of heritable evolutionary change:-

But since the present sketch is the germ of the Essay of 1844, it seemed best to preserve the identity between the two works, by using such of the author's divisions as correspond to the chapters of the enlarged version of 1844.

There is much erasure and correction, apparently made at the moment of writing, and the MS.

The automatic assumption that Russia shorn of its expansionist communist ideology should pick up where the czars left off just prior to the Bolshevik Revolution is therefore a curious one. It assumes that the evolution of human consciousness has stood still in the meantime, and that the Soviets, while picking up currently fashionable ideas in the realm of economics, will return to foreign policy views a century out of date in the rest of Europe. This is certainly not what happened to China after it began its reform process. Chinese competitiveness and expansionism on the world scene have virtually disappeared: Beijing no longer sponsors Maoist insurgencies or tries to cultivate influence in distant African countries as it did in the 1960s. This is not to say that there are not troublesome aspects to contemporary Chinese foreign policy, such as the reckless sale of ballistic missile technology in the Middle East; and the PRC continues to manifest traditional great power behavior in its sponsorship of the Khmer Rouge against Vietnam. But the former is explained by commercial motives and the latter is a vestige of earlier ideologically-based rivalries. The new China far more resembles Gaullist France than pre-World War I Germany.


Charles Darwin's theory of evolution: A .

For Kojève, as for all good Hegelians, understanding the underlying processes of history requires understanding developments in the realm of consciousness or ideas, since consciousness will ultimately remake the material world in its own image. To say that history ended in 1806 meant that mankind's ideological evolution ended in the ideals of the French or American Revolutions: while particular regimes in the real world might not implement these ideals fully, their theoretical truth is absolute and could not be improved upon. Hence it did not matter to Kojève that the consciousness of the postwar generation of Europeans had not been universalized throughout the world; if ideological development had in fact ended, the homogenous state would eventually become victorious throughout the material world.

In some circles, however, opposition to the concept of evolution has persisted to the present. The argument from design has recently been revived by a number of academics with scientific credentials, who maintain that their version of the idea (unlike Paley’s) is soundly supported by both microbiology and mathematics. These antievolutionists differ from fundamentalist creationists in that they accept that some species do change (but not much) and that Earth is much more than 6,000 years old. Like their predecessors, however, they reject the idea that evolution accounts for the array of species we see today, and they seek to have their concept—known as intelligent design—included in the science curriculum of schools.

Most biologists have concluded that the proponents of intelligent design display either ignorance or deliberate misrepresentation of evolutionary science. Yet their proposals are getting a hearing in some political and educational circles and are currently the subject of a debate within the Ohio Board of Education. Although Natural History does not fully present and analyze the intelligent-design phenomenon in the pages that follow, we offer, for the reader’s information, brief position statements by three leading proponents of the theory, along with three responses. The section concludes with an overview of the intelligent-design movement by a philosopher and cultural historian who has monitored its history for more than a decade.
