Neither Pasteur, nor any other post-Darwin researcher in this field, denied the age of the earth or the fact of evolution.
A recurring theme in antievolution literature is that if science cannot account for the origin of life, evolution is false, and that "spontaneous generation" was disproven, so therefore evolution is false.
In the "So with animals, some spring from parent animals according to their kind, whilst others grow spontaneously and not from kindred stock; and of these instances of spontaneous generation some come from putrefying earth or vegetable matter, as is the case with a number of insects, while others are spontaneously generated in the inside of animals out of the secretions of their several organs." "As a general rule, then, all testaceans grow by spontaneous generation in mud, differing from one another according to the differences of the material; oysters growing in slime, and cockles and the other testaceans above mentioned on sandy bottoms; and in the hollows of the rocks the ascidian and the barnacle, and common sorts, such as the limpet and the nerites." "Other insects are not derived from living parentage, but are generated spontaneously: some out of dew falling on leaves, ordinarily in spring-time, but not seldom in winter when there has been a stretch of fair weather and southerly winds; others grow in decaying mud or dung; others in timber, green or dry; some in the hair of animals; some in the flesh of animals; some in excrements: and some from excrement after it has been voided, and some from excrement yet within the living animal, like the helminthes or intestinal worms." "Other animalcules besides these are generated, as we have already remarked, some in wool or in articles made of wool, as the ses or clothes-moth.
And these animalcules come in greater numbers if the woollen substances are dusty; and they come in especially large numbers if a spider be shut up in the cloth or wool, for the creature drinks up any moisture that may be there, and dries up the woollen substance. A creature is also found in wax long laid by, just as in wood, and it is the smallest of animalcules and is white in colour, and is designated the acari or mite.
All these accounts rely on the innate (or natural; the Greek word is phusis, from which we get "physics") properties of the elements of the universe. In (384-322) we get the most sophisticated of all these Greek views.Then we will look at the modern - post-Pasteur and post-Darwin - developments in Origins of Life research.The first western thinker to suggest that life arose spontaneously was probably , a Milesian philosopher (in what is now Turkey) who wrote in the 6th and 5th centuries before Christ (611-547 BCE).In this assertion they are mistaken, for the female of the fish is found provided with spawn, and the male with milt.However, there is a species of mullet that grows spontaneously out of mud and sand.
He too held to a spontaneous generation of fully formed plants and animals under the influence of the sun.
