Incompleteness of the Fossil Record
▪ Fossilisation is an exceptionally rare occurrence that requires an unusual combination of special conditions
▪ Most living things tend to decompose rapidly (or be scavenged) following death
▪ Fossilisation tends to favour hard body parts (bone, teeth, shells, etc.) and exposed fossils will soon be weathered / destroyed
▪ Only a small percentage of fossils have been discovered - fossilisation favours species that were long-lived and widespread
Significance of Incompleteness of the Fossil Record
▪ Individual fossils may not be representative of species (e.g. Homo floresiensis - 'Hobbit' man)
· Very few complete skeletons have been discovered, and so paleoanthropology is an inductive (data-poor) science
· Many conclusions have been drawn on limited data and are frequently re-interpreted in the light of new discoveries
