Humans and chimps each have some 3 billion base units of DNA in their genomes, differing by only 1.2 percent when compared in this way. Other methods of comparison estimate a genetic difference of at most 4 percent.
"We're not that different," Waterston said.
But we have language, cars, espresso machines and psychotherapy. How could all that result from just a comparatively small number of genetic changes in the overall blueprint?
Waterston acknowledges that scientists are a long way off from answering such questions. But we're getting closer, he says. He noted one gene, known as FOXP2, that may help explain why we talk and chimps don't. An earlier study of a British family with an inherited, severe deficit in speech discovered the cause of the disorder -- an altered form of FOXP2.
"It turns out chimps have the same (genetic) sequence as that family with the speech deficit," Waterston said. Comparing the human and chimp genomes, he said, shows that the speech-friendly form of FOXP2 really took hold in humans some 150,000 years ago.
The Nature report written by the UW scientist and his team ends: "We hope that elaborating how few differences separate our species will broaden recognition of our duty to these extraordinary primates who stand as our siblings in the family of life"

Moreover, "fact" does not mean "absolute certainty." The final proofs of logic and mathematics flow deductively from stated premises and achieve certainty only because they are not about the empirical world. Evolutionists make no claim for perpetual truth, though creationists often do (and then attack us for a style of argument that they themselves favor). In science, "fact" can only mean "confirmed to such a degree that it would be perverse to withhold provisional assent." I suppose that apples might start to rise tomorrow, but the possibility does not merit equal time in physics classrooms.

Why are they so certain of such nonsense when it isn't rational to automatically think that the human race is flawed because of religion?
