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:
“What we think of as our sensitivity is only the higher evolution of terror in a poor dumb beast. We suffer for nothing. Our own death wish is our only real tragedy.”
—Mario Puzo (b. 1920)
