1.
There is a continuous uninterrupted line of descent from
the first organisms that arose ~3.5-billion years ago,
and all living organisms. |
|
|
2.
The spontaneous generation of organisms does not occur
in the modern world, but did occur on the early earth. |
|
|
3.
Based on a number of structural and molecular traits,
organisms can be divided into three distinct ‘kingdoms’: bacteria, archaea and eukarya. |
|
|
4.
All modern organism shared a common ancestor that lived
some billions of years ago. |
|
|
5.
Modern eukarya are hybrid organisms, formed by the combination
of a bacterial and a non-bacterial cell. |
|
|
6.
Modern multicellular plants (metaphyta), fungi,
and animals (metazoa)
arose independently from eukaryotic ancestors. |
|
|
7.
All metazoa appear to share a common ancestor that lived
around ~1.5 billion years ago. |
|
|
8.
The original hierarchical classification system of organisms,
the Linnaean system) was based on structural similarities,
not evolutionary relationships. |
|
|
9.
Evolutionary theory explains the relationships between
organisms, based on common ancestry. |
