This series, Planet of Life, presents the history of evolution on this planet. Originally produced for the Discovery Channel, each episode covers a separate chapter in the biography of the world. This episode examines the evolution of humans with the use of computer animation. This video posits that one group of primates moved onto the plains where they evolved the ability to stand upright, in order to survive. These inhabitants of the …show more content…
swinging through the trees, chimps found breakiating was a more efficient form of locomotion.
Professor : we are the only animalsthat walk habitually on two lower limbs in a terrestrial niche on the ground and thats the best mark for locomotion. : we sacrifice speed and some of the agility of the african apes( our closest relatives) who can scrable up a tree. : bipeadality, for reasons we are not so sure even today, confered a selective advantage on early homonids about 4 to 5 million years ago. and walking on two legs, became a fashion, a hallmark of our species. ;To this day, the cause of this biological lift between african apes and humansremains unknown. : with few fossils more, solving the mystery with what transpired why humans and apes parted ways has challenged researchers acrossthe globe.
Dr. Satoshi Harahi of Japan's NAtional institute of genetics: compares genetic maps in search of clues. : as the number of generation increase so is the number of difference in genes in trhe animals that branch off our primate ancestors. : detailed examintaion of these differences can pinpoint when humans and chimpanzees split from their common lineage. : the humans and chimpanzees split off from one another, in the figures, during 4.9 million years ago. based on the total number of base sequence, so the margin of error is only about 200,000 years ( an extremely small margin). HUmans and chimps branched out about 5 million years ago.
