If you're on safari in Africa and spot a tiger, it's definitely something
to write home about. Tigers as we know them, you see, have never lived in
the wild in Africa. But there's still a chance you could see one there. Let
us explain.

Lions, leopards and tigers are all part of the Felidae family of cats,
which originated in Africa and share a common ancestor. At some point,
probably around 2 million years ago, one offshoot of Felidae migrated east
toward Asia, and those cats evolved into the orange-, black-, and
white-striped beasts we know today. Once established in Asia, however,
tigers never returned to Africa, although scientists aren't exactly sure
why.

"One can offer a series of speculations about why tigers did not get to
Africa, but they are all speculations," said J.L. David Smith, professor at
the University of Minnesota's department of fisheries, wildlife and
conservation biology. "The best explication is time."

Many wildlife researchers believe that, historically, tigers inhabited much
of Asia, and that various tiger subspecies naturally migrated and spread
out over time. Pleistocene glacial fluctuations and geographic boundaries,
however, probably made it too difficult for tigers to return to Africa.
According to University of Minnesota conservation biology researcher
Shu-Jin Luo, tigers did not disperse westward to India until 16,000 years
ago.

Now, although tigers are not indigenous to Africa, they can be found there
in zoos, special reserves and even

The *tiger* (/Panthera tigris/) is the largest cat species, reaching a
total body length of up to 3.3 m (11 ft) and weighing up to 306 kg
(670 lb). It is the third largest land carnivore (behind only the polar
bear and the brown bear). Its most recognizable feature is a pattern of
dark vertical stripes on reddish-orange fur with a lighter underside. It
has exceptionally stout teeth, and the canines are the longest among living
felids with a crown height of as much as 74.5 mm (2.93 in) or even 90 mm
(3.5 in).^[4] In zoos, tigers have lived for 20 to 26 years, which also
seems to be their longevity in the wild.^[5] They are territorial and
generally solitary but social animals, often requiring large contiguous
areas of habitat that support their prey requirements. This, coupled with
the fact that they are indigenous to some of the more densely populated
places on Earth, has caused significant
