"DNA analysis for chimpanzees and humans reveals striking differences in genes for smell, metabolism and hearing." Cornell News.The genes involved also affect long-bone growth, hairiness and hearing - the last of which is closely connected to the development of speech. Researchers suggest that a dietary change brought on by sudden climate change may be the key catalyst behind the explosions in evolution that separated humans and chimps from our most recent common ancestor. Chimps are only surpassed in meat consumption by humans. The hierarchy also exists when you look at meat consumption among primates. Obviously, humans are the most evolved primate species on the planet, with chimps coming in second. The Cornell team found hundreds of gene sequence changes in areas related to, among other things, smell and digestion. In comparing genetic differences between humans and other apes, scientists at Cornell University reached a theory that the split between humans and chimps might have very well come down to issues of scent and taste. Then, 2 million years ago, a similar genetic burst splintered humans off from the rest of the apes. Scientists believe that an explosion of just such genetic changes caused the lineage of the great apes to branch off from the lesser, tailed primates 10 million years ago. In other words, it's not just what the genes are, but how they're expressed. Mojo Risin.'" Among humans, copy number variation can distinguish one identical twin from another and have also been associated with various diseases, such as AIDS. If we were to compare it to something as simplistic as human names, on one hand you have the name "Jim Morrison," which is different from "Jim Jim Morrison," Morrison Jim" or the Doors front man's anagram pseudonym, "Mr. These include code repetitions, deletions and backward sequences. While human and chimps share similar gene sequences, copy number variations can differ greatly. Such differences depend on often slight genetic details. Chimps, on the other hand, have separate male and female hierarchies.
Human males and females, however, share a deeper conjugal bond, creating family-based society. Our two species still share such bloody traits as male kin bonding and lethal territorial aggression. The consensus is that although humans have evolved socially from our last common ancestor, chimps have remained largely the same. Under "social emotions," you'll find a whole Pandora's box of human characteristics, including empathy, guilt and embarrassment. We also share between 94 and 99 percent of the same genes, depending on the study.
In fact, go back 5 or 6 million years and you'd find a common ancestor that both humans and chimps share. Among the apes, humans have the most in common with chimps. We're all tailless primates, belonging to either the Hylobatidae family (in the case of gibbons) or the Hominidae family, which encompasses chimpanzees, bonobos, orangutans, gorillas and human beings. And unlike kittens or distant constellations, we actually have a great deal in common with apes. It's not surprising then that we stare at gorillas and chimpanzees and see aspects of ourselves: the bestial, the innocent, the savage and the adorable. We've even gazed into the night sky and marked the shape of our own ephemeral bodies against the timeless spill of stars. It's nearly impossible for us to mark two dots on a sheet of paper without seeing a pair of eyes staring back at us. We establish emotional connections to animals with facial features resembling our own infants. Human beings see themselves in everything. What really separates a human child from the beloved chimp?
