Scientists sometimes say that the more we know, the more questions there are to answer. Not only do advances in sciences produce new questions, such as working and workable theories in quantum mechanics in physics — there is also a vast trove of stuff to know in other areas.
For example, as humans more carefully explore Earth, we keep finding species previously unknown. We call them “new” species, but of course, they are not new. They are living populations which have simply escaped the notice of humans, or of humans who publish in science magazines.
I found this account of new monkey species at . . .free your imagination, a blog dedicated to such esoteric and up-to-date knowledge. (Found it through WordPress’s “tag surfing” feature.)
38 primate species have been described since 1990, and there are at least 20 more, known, but not yet described. This should excite kids who want to be scientific explorers.
And, true to form, anti-conservationists will point to this fact of “new” species, and argue that we have no need for the Endangered Species Act. Just watch.
What else do we not know?
