Thus, interpreting the Ardipithecus - bearing sediments requires that we deduce the physical and biological conditions under which the fossils accumulated and the degree to which these biases operated at the time
of deposition — a practice called «
taphonomy.»
These include: 1) finding and describing new fossils in Precambrian strata, 2) using analytical tools to examine those fossils in order to determine taxonomic affinity,
taphonomy, functional morphology, and paleoecology, 3) using modern analogs to determine phylogenetic relationships and physiology
of early eukaryotes and animals, and 4) combining multiple sources
of data to create a timeline
of biotic and abiotic events in the Precambrian.
