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.
