History
In the 19th century, some scientists such as Jean-Baptiste Lamarck and Ray Lankester believed that all Nature had an innate striving to become more complex with evolution. This belief may reflect then-current ideas of Hegel and Herbert Spencer that all creation was gradually evolving to a higher, more perfect state.
According to this view, the evolution of parasites from an independent organism to another parasite was seen as "devolution" or "degeneration", and contrary to Nature. This view has sometimes been used metaphorically by social theorists and propagandists to decry a class of people as "degenerate parasites". Today, "devolution" is regarded as nonsense; rather, lineages will become simpler or more complicated according to whatever forms have a selective advantage.

Famous quotes containing the word history:
“While the Republic has already acquired a history world-wide, America is still unsettled and unexplored. Like the English in New Holland, we live only on the shores of a continent even yet, and hardly know where the rivers come from which float our navy.”
—Henry David Thoreau (1817–1862)
“A man acquainted with history may, in some respect, be said to have lived from the beginning of the world, and to have been making continual additions to his stock of knowledge in every century.”
—David Hume (1711–1776)
“Let us not underrate the value of a fact; it will one day flower in a truth. It is astonishing how few facts of importance are added in a century to the natural history of any animal. The natural history of man himself is still being gradually written.”
—Henry David Thoreau (1817–1862)
