• study of living things

• change over time

• study of non-living things

In 520 BC he speculated that life had a single origin and that it was simpler in the past and has become more complex.

• Erasmus Darwin

• John Ray

• Xenophanes

• Anaximander

• Aristotle

He published Zoonomia, in which he agreed that all living things were descended from a single ancestor and that they had diversified into the various forms seen today due to competition and social interaction

• Erasmus Darwin

• John Ray

• Aristotle

• Anaximander

• Xenophanes

Georges Cuvier believed what?

• Catastrophism causes extinction

• Catastrophism causes evolution

He proposed an early definition of a species and that individuals of a species are similar due to descent from a common ancestor in his book, History of Plants

• Erasmus Darwin

• John Ray

• Xenophanes

• Anaximander

• Aristotle

He proposed a hierarchical scheme that he felt revealed a divine order of living things in his book on classification

• Erasmus Darwin

• John Ray

• Xenophanes

• Carolus Linnaeus

• Plato

This developed from modeling of inheritance of multi-factorial phenotypes

• Molecular Biology

• Quantitative Genetics

• Orthogenesis

• Mutationism

• Population Genetics

This developed from modeling of evolution of genes in populations

• Molecular Biology

• Quantitative Genetics

• Orthogenesis

• Mutationism

• Population Genetics

This involves wealth of discoveries about genes and genomes integrated into genetic theory

• Molecular Biology

• Quantitative Genetics

• Orthogenesis

• Mutationism

• Population Genetics

Its concept focuses on new species originated when they mutated from pre-existing species, but this process was independent of natural selection, which only affected the composition of populations.
