Evidences of Evolution

It is the change in the characteristics of a species over several generations

Any trace or remain of an organisms that has been preserved by natural processes

They are traces of organisms that lived in the past and were preserved by natural process or catastrophic events

A person who studied fossils

Shallow external molds left by animal or plant tissues with little or no organic material presented

The organic side with more organic material

A method used to determine the age of rocks by comparing them with the rocks in the other layers

Provides more specific origin of dates, time and numerical data range such as the range of specific fossils

Shows the major events in the Earth’s history

Measured in billions of years

The largest division of Geologic Time Scale

Measured in tens of millions of years to hundred million of years

The smallest unit and are usually to measured in million of years to tens of millions of year

The study of the similarities and differences in the structure of different species

Same structure, different function

Different structure, same function

No functions

The splitting of an ancestral population into two or more subpopulations that are geographically isolated from one another.

Analogous structures of unrelated organisms from different ancestors develop similar function
