Cause of variations: genetic combinations, chromosomes, DNA, genes; mutations

Formation of new species: allopatric speciation, phyletic gradualism, punctuated equilibrium

Evolutionary Patterns: divergent evolution, convergent evolution, parallel evolution

Compare the theories of natural selection and inheritance of acquired characteristics. How are they similar and how are they different? What causes the variations required in natural selection?

Describe three ways in which a new species may form. (allopatric speciation, phyletic gradualism, punctuated equilibrium)
