Question

Describe is pre Darwin and post Darwin theory?

Answer 1

pre Darwin's theory
*.All aspects of nature were considered as fixed and change was inconceivable.
*.No new species had appeared, and none had disappeared or become extinct. The social and political context of the Middle Ages helps explain this world view:
*.shaped by feudal society - hierarchical arrangement supporting a rigid class system that had changed little for centuries
*.shaped by a powerful religious system - life on Earth had been created by God exactly as it existed in the present (known as fixity of species).This social and political context, and its world view, provided a formidable obstacle to the development of evolutionary theory. In order to formulate new evolutionary principles, scientists needed to:
*.overcome the concept of fixity of species
*.establish a theory of long geological time

Darwin's theory
the theory of evolution states that evolution happens by natural selection.
individuals in a species show a wide range of variation this variation is because of differences in their genes individuals with characteristics most suited to the environment are more likely to survive and reproduce the genes that allow these individuals to be successful are passed to their offspring.
