Imprints

Absolute dating
Shows the major events in the Earth’s history
Geologic Time Survey
Measured in billions of years
Eon
The largest division of Geologic Time Scale
Era
Measured in tens of millions of years to hundred million of years
Periods
The smallest unit and are usually to measured in million of years to tens of millions of year
Epochs
The study of the similarities and differences in the structure of different species
Comparative Anatomy
Same structure, different function
Homologous Structure
