Why most scientists support the theory of evolution

Mutations in these primary on/off switches are involved in such phenomena as the loss of legs in snakes, the change from lobe fins to hands, and the origin of jaws in vertebrates.HOX-initiated segment duplication allows for anatomical experimentation, and natural selection winnows the result. “Evo-Devo” — the study of evolution and development — is a hot new biological research area, but Wells implies that all it has produced is crippled fruit flies.

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

The Evolutionary Theory of Aging and Life History Theory

China could not now be described in any way as a liberal democracy. At present, no more than 20 percent of its economy has been marketized, and most importantly it continues to be ruled by a self-appointed Communist party which has given no hint of wanting to devolve power. Deng has made none of Gorbachev's promises regarding democratization of the political system and there is no Chinese equivalent of glasnost. The Chinese leadership has in fact been much more circumspect in criticizing Mao and Maoism than Gorbachev with respect to Brezhnev and Stalin, and the regime continues to pay lip service to Marxism-Leninism as its ideological underpinning. But anyone familiar with the outlook and behavior of the new technocratic elite now governing China knows that Marxism and ideological principle have become virtually irrelevant as guides to policy, and that bourgeois consumerism has a real meaning in that country for the first time since the revolution. The various slowdowns in the pace of reform, the campaigns against "spiritual pollution" and crackdowns on political dissent are more properly seen as tactical adjustments made in the process of managing what is an extraordinarily difficult political transition. By ducking the question of political reform while putting the economy on a new footing, Deng has managed to avoid the breakdown of authority that has accompanied Gorbachev's . Yet the pull of the liberal idea continues to be very strong as economic power devolves and the economy becomes more open to the outside world. There are currently over 20,000 Chinese students studying in the U.S. and other Western countries, almost all of them the children of the Chinese elite. It is hard to believe that when they return home to run the country they will be content for China to be the only country in Asia unaffected by the larger democratizing trend. The student demonstrations in Beijing that broke out first in December 1986 and recurred recently on the occasion of Hu Yao-bang's death were only the beginning of what will inevitably be mounting pressure for change in the political system as well.

Darwin's Ancestors: The Evolution of Evolution

In the evolutionary process, an increase in biological complexity does not represent a “free lunch” — it is bought and paid for, because random genetic variation is subjected to natural selection by the environment, which itself is already structured. In fact, researchers are beginning to use Darwinian processes, implemented in computers or in vitro, to evolve complex systems and to provide solutions to design problems in ways that are beyond the power of mere intelligent agents.

There is much erasure and correction, apparently made at the moment of writing, and the MS.
An eminent scientific contemporary, Thomas Henry Huxley, later recorded his own reaction to the emergence of the Theory of Evolution:-

Brief Essay on the Lamarck's Theory of Evolution

Three proponents of Intelligent Design (ID) present their views of design in the natural world. Each view is immediately followed by a response from a proponent of evolution (EVO). The report, printed in its entirety, opens with an introduction by Natural History magazine and concludes with an overview of the ID movement.

The geological discussion with which Part II begins corresponds to two chapters (IV and V) of the 1844 Essay.

By far the most important were the bird notes, for they contained the expansion of the brief account, written in the Galapagos in September 1835 of the three species of Mocking Birds (Thenca) found in the islands, into Darwin's realisation that these birds might provide the first example of island endemism, (or distinct specific type island by island), and hence of evidence that new species had been created.
