The Future is Wild has been around for a while. It was first shown on Animal Planet as a 3 hour mini-series, but was then divided into several episodes for seperate viewing, adding supplemental material. Some of the ideas are nifty, but the CG is no Walking with Dinosaurs, and they reuse it often.
In summary, humans are pretty much gone. 5 million years from now, the world is a very hostile environment, mostly deserts both warm and cold. Gannets (seabirds) have evolved into walrus-y things, there are few true carnivores (cats, dogs, bears, etc) or primates left, and giant bats soar on thermals to catch prey. In 50 million years, there are giant turtles, amphibious octopi, and spiders that farm the last mammals for food. In 200 million years, the invertabrates rule. The most complex life with bones are "flish", as in winged fish. And the heirs to humanity emerge, and they are the squibbons- tree-dwelling, semi-sentient, tool using, socialist squid.
All in all, it's a little goofy, not nearly as good as After Man, but entertaining (especially squibbons). The worst part of the series are the terrible names of the future creatures. Sharkopath indeed (you guessed it, phosphorescent pack-hunting sharks).
Demiurge out.
