We are inescapably the result of a long heritage of learning, adaptation, mutation and evolution, the product of a history which predates our birth as a biological species and stretches back over many thousand millennia... Going further back, we share a common ancestry with our fellow primates; and going still further back, we share a common ancestry with all other living creatures and plants down to the simplest microbe. The further back we go, the greater the difference from external appearances and behavior patterns which we observe today.
If the resident zoologist of Galaxy X had visited the earth 5 million years ago while making his inventory of inhabited planets in the universe, he would surely have corrected his earlier report that apes showed more promise than Old World monkeys and noted that monkeys had overcome an original disadvantage to gain domination among primates. (He will confirm this statement after his visit next year but also add a footnote that one species from the ape bush has enjoyed an unusual and unexpected flowering, thus demanding closer monitoring.)stephen jay gould
Put away these frozenjawed primates and their annals of ways beset and ultimate dark. What deity in the realms of dementia, what rabid god decocted out of the smoking lobes of hydrophobia could have devised a keeping place for souls so poor as in this flesh. This mawky wormbent tabernacle.cormac mccarthy
I think that intelligence is such a narrow branch of the tree of life - this branch of primates we call humans. No other animal, by our definition, can be considered intelligent . So intelligence can't be all that important for survival , because there are so many animals that don't have what we call intelligence, and they're surviving just fine.
We freely acknowledge that there is room for differences of opinion on such problems as species formation and the mechanisms of evolutionary change. Nevertheless, we are convinced that masses of evidence render the application of the concept of evolution to man and other primates beyond serious dispute.
People may choose to ignore their animal heritage by interpreting their behavior as divinely inspired, socially purposeful, or even self-serving, all of which they attribute to being human, but they masticate, fornicate, and procreate, much as chimps and apes do, so they should have little cause to get upset if they learn that they act like other primates when they politically agitate, debate, abdicate, placate, and administrate, too.arnold m. ludwig
