Here’s a passage of scientific prose to savor:
It was widely thought that de novo evolution of genes was quite rare, because the proteins they code for are often large and complex — most fail to function properly if a single key component is out of place, so randomly evolving a working gene seemed implausible.
When an international team of researchers scanned the human genome for de novo genes, however, they putatively uncovered 60, three times more than once estimated.

- Evolution predicts X.
- We observe ~X.
- Well, go figure. Evolution predicts X and ~X.
