Lack of fossils
‘Palaeoanthropologists seem to make up for a lack of fossils with an excess of fury, and this must now be the only science in which it is still possible to become famous just by having an opinion. As one cynic says, in human palaeontology [the study of fossils] the consensus depends on who shouts loudest.’
