G. H. R. von Koenigswald, in "Early Man: Facts and Fantasy", p. 67:
When I say 'our science' I mean what is called the science of Early Man or Palaeoanthropology, of which one quarter is anthropology, another palaeontology, another archaeology, and the last quarter is composed of fantasy, intuition, hard work and good luck, because our early ancestors really are elusive. What in more than a hundred years has been discovered of Neanderthal Man, fills but a small churchyard. What is known of pre-Neanderthal Man can be placed on two middle-sized tables, and what might belong to our Tertiary ancestors I can put on the palm of my hand. You can expect traces of Early Man practically everywhere, in caves, sand pits, and Chinese drugstores, but the hunt is still difficult, you have to be hunter and dog in one person.

Ann Miller in On the Town:
Yes, you see there are not too many modern males who can measure up to the prehistoric.
"Instapundit" Glenn Reynolds, contrasting the idea of trans-fat bans with the infamous fast food rat problem in NYC:
Before they start with their bureaucrat-empowering agenda of 21st-century health initiatives, maybe they should get a handle on the 19th-century health problems first.
Last words of the real-life Bat Masterson, found "in his typewriter in the column he had been writing":
There are those who argue that everything breaks even in this old dump of a world of ours. I suppose these ginks who argue that way hold that because the rich man gets ice in the summer and the poor man gets it in the winter things are breaking even for both. Maybe so, but I'll swear I can't see it that way.
J. B. S. Haldane, first line of "A mathematical theory of natural and artificial selection" (1924, Trans Camb Phil Soc 23:19-41):
A satisfactory theory of natural selection must be quantitative.
