Darwin proposed that natural selection favors individuals that are best able to survive and reproduce. 3. Under certain conditions, change within a species can lead to new species. 4. Gradualism is a process of evolution in which speciation occurs gradually, and punctuated equilibrium is a process in which speciation occurs rapidly between periods of little or no change. Evidence of Evolution 5. Evidence of orderly change can be seen when fossils are arranged according to their age. 6. Differences in amino acid sequences and DNA sequences are greater between species
