I love when we discover stuff. Really! I love science. We are such curious beings, yet, we fall into the trap of complacency so easily, don't we? One of the many conundrums of humanity.
Here is a Yahoo! story about a bunch of previously undocumented species (they call them "new") that reminds me of my favorite word when I read stories about how much we pretend to know: hubris.
"More than 1,700 new species have been described by science in the Greater Mekong since 1997. In 2011, 82 plants, 13 fish, 21 reptiles, five amphibians and five mammals were discovered."
We just don't know what we think we know, you know?
