Genetics and Evolution
Analysis of DNA is consistent with the hypothesis that Sumatran tigers have been isolated from other tiger populations after a rise in sea level that occurred at the Pleistocene to Holocene border (about 12,000-6,000 years ago). In agreement with this evolutionary history, the Sumatran tiger is genetically isolated from all living mainland tigers, which form a distinct group closely related to each other.

Famous quotes containing the word evolution:
“The more specific idea of evolution now reached is—a change from an indefinite, incoherent homogeneity to a definite, coherent heterogeneity, accompanying the dissipation of motion and integration of matter.”
—Herbert Spencer (1820–1903)
