how can fossils be formed?
parts of organisms that have not been decayed due to conditions needed for decay being absent
parts of organisms that have been replaced by minerals as they decayed e.g. bones
as preserved traces of organisms, covering in sediment & becoming rock
why are there few traces of early life forms left behind?
many were soft bodied which would decay
what can we learn from fossils?
how much or how little organisms have changed as life developed
