Jeffrey H. Schwartz Quotes

From a succession of historians we learn of a particularly gruesome component of Carthaginian daily life: the routine and ritualized sacrificing of not just animals—animal sacrifice was a common religious activity of all Mediterranean cultures—but of infants and children. ...Greek and Roman historians were unanimous in their abhorrence of the Carthaginian practice...

The smaller the mammal, the more it is confined to smaller geographic areas. A small mammal is also more susceptible to subtle changes in climate and environment. ...On average, the absence or presence of smaller species provides more precise clues to past conditions in an area than does the information gained from study of the bone assemblages of the larger animals.

Becoming a rock does not ensure safety. ...The blasting of windblown sands, the pummeling of waves, the corrosive secretions of mosses and lichens, and even the steady rhythm of a stream can, in time, reduce a seemingly indestructible boulder to a grain of sand.

The processes of bone preservation are such that the farther back in time we go, the less there is.

There are always alternative interpretations of the same data. It is often the case, however, that the alternatives that are rejected are treated as if they don't exist. But they do. And we should be aware not only of their existence and potential viability, but of the possibility that the hypotheses that we might embrace so strongly today may very well be the rejects of tomorrow.

A "new" systematics will be forthcoming only when the urge to be "right" takes a back seat to the possibility that one is wrong.

The often heated and sometimes nasty debates that have taken place between gradualists and punctuationists, or between micromutationists and macromutationists, have been generated by the perception that there is only one evolutionary question, for which... there can be only one correct answer. ...But if we take a different approach, and assume that both sides of a typical evolutionary debate have something valid to offer, then the theoretical and methodological disagreements between different schools of thought may just be a matter of having the right answer to a different question.

Science, especially evolutionary sciences, can only proceed from learning about theories of hypotheses that do not stand the test of time.

A micromutation can produce what Goldschmidt would have described as macromutation leading to macroevolution. Since mutations in homeobox genes are inherited in the same way that earlier fruit-fly population geneticists understood the inheritance of the alleles for wing length or bristle number, we can appreciate that evolutionarily significant novelty—which, in turn, could result in the emergence of a new species—can be passed on from parent to child as easily and simply as eye color.

The Bodo skull and the Kaprina and Shanidar Neandertal skeletons raise the possibility that two distinct, non-spaiens species of Homo had had rituals and cultural practices that we have assumed are only within the capacity of members of our own species.
