Based on Scientific evidence, they're genetically closest to us. These Animals have already advanced into using tools to hunt, that was the first step that our ancestors took several hundred thousand years ago.
Marine dwellers. The manatee is a grazer descended from land-living herbivores and spends its entire life in the water. Near south-eastern America, there live dolphins that specialise in synchronically 'herding' fish on to the river banks before feeding and the tumultuous breeding habits of southern right whales are shown off the shores of Patagonia.
These bears are extremely well adapted to the cold and Ice. The white fur helps them to move stealthily and under their fur is 4 inches of blubber that insulates against the cold. Polar Bears are the largest land carnivores and they are found in the Arctic. Adult male can weigh up to 1500 lbs. in weight and the females up to 750 lbs.
Specialist hunting strategies demand particular adaptations of the body, from fearsome teeth to scimitar sharp claws and tusks. Witness the insidious nature of chemical warfare employed by many animals. All manner of snakes, spiders, lizards and marine life have developed venoms, either as weapons of attack or defense.In the competitive struggle for survival, less powerful animals have developed an ingenious array of strategies to find and kill their targets. Traps, lures and lies may be the best-known tricks to man, but are also skilfully employed by creatures in the animal kingdom.
What happens when one of these magnificent beasts dies in the wild? The documentary gives scientists the chance to watch close up, day and night, as animals from leopards, hyenas and vultures to flies and beetles take just days to reduce the largest land animal on earth to bare bones. This stunning film turns normal wildlife documentaries on their head to find out what happens after death, as a five ton adult elephant is transformed into six million calories worth of fat, meat and guts, feeding a whole new cycle of life.
