Question

Consider lineages, such as our own, for which the fossil record is fragmentary and incomplete. What disadvantages does this confer upon scientists trying to fathom the history of our species? What useful things can be learned from one or a few fragments of bone?

Answer 1

Fossils tells us about the evolution of the species how they existed on the earth , their habitat, and how the got extinct and if incomplete fossils and records are obtained scientists will face a difficulty in recognizing about the ancestors of the organism.

The bone fragment can tell many things about the organism

Deposition of the material in bone tells about how long ago was it buried

The size of bones may help to determine the age the ephiphysealgrowth in long bin may also tell about the age the fragility can tell about the sex of the person the markings or trauma can tell about how the death occurred the parts which are evolutionary can be compared with the todays generation.
