This influenced Darwin's theory of Evolution, because it shows, that things are constantly changing on earth (the enviorment) so why can't organisms?

• What is Lamarcks hypothesis of Evolution?

• What was Cuvies way of thinking about catastrophism?

  Cuvier thought that each boundary between strata represented a catastrophe which destroyed many lifeforms at that place but eventually species from other places would refill the areas.

• What was the theory of Cuvier?

  Cuviers theory was that extinctions must have been a common occurrence throughout history. Even though he saw different species in different strata, he denied the existence of evolution and introduced catastrophism.

• What did Darwin think of the classification system of Linneaus?

  Darwins idea of classification was that it should be based on evolutionary relationship, not by the patterns of their creation.

• Who is Carolus Linneaus?

  C. Linneaus was a Swedish scientist who sought to classify lifes diversity. He called it: For the greater glory of God.

• What were the Old Testaments: account of creation?

• What is the theory of Darwin?

  Darwins theory was that animals would adapt to their environment such as natural selection.
