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:
“By contrast with history, evolution is an unconscious process. Another, and perhaps a better way of putting it would be to say that evolution is a natural process, history a human one.... Insofar as we treat man as a part of nature—for instance in a biological survey of evolution—we are precisely not treating him as a historical being. As a historically developing being, he is set over against nature, both as a knower and as a doer.”
—Owen Barfield (b. 1898)
